If you manage to use Google translate that is definitely better. My experience with translation of the whole document was moderate. But this is for sure faster.

Great results Overscan!
One remark according to page I put link, (Maybe it is obvious, If yes - sorry for such low level of remark ;-) )
It is possible to download ppt file . In preview of file on that page - formatting of all diagrams in ppt is not correct.
Personally I download all content of those lectures B)

Interesting. so the N019 has 6.5 kW instead of 4 kW of peak power. and 960 doppler filters. It also interesting to see the detection and tracking criteria being related to probability (detection is 0.5/50% while tracking is 90%)

Great find LukaszK and nice translation Overscan.

Yes, I'm using the PPT version. I will upload the PPT version if you want to correct it :)

Having done machine translation before on this very subject, I know some of the trickier terms and can tidy up the translation somewhat.

Hi there,

I have some dumb situation to solve.

I come from another forum. We debate the performance of MiG-29 radar. I am generally satisfied with the level of understanding several other members debating this issue display, and yes, we have the manual. Back in my days I had no problem with the manual, yes it demands some knowledge prior to reading, but nothing too demanding.

Currently we are having an exchange with some troll, who claims that MiG-29 radar after launching R-27R performs both scanning (search) of airspace for other targets while guiding R-27R on attacked one. As crazy as it sounds, but picture this - manual never says explicitly that radar lock have to be maintained until missile impact and that while that lock is maintained all other targets disappear (writers believe we already know that). Further manual is rather liberal in using terms such as "lock", tracking, automatic tracking, etc and *very liberal* in using word "regime" (eng. "mod") they describe a wide array of terms from real, selectable mods like "V" or "D" to some sub operations which system performs "behind the scene" i.e. invisible to the pilot and not shown anywhere like "mod" DNP. Add to this a host of people who are unsure what to believe and it is a perfect stage for an ambitious troll to do all kinds of logical and linguistic aerobatics. At one moment he used some data from "overscan's" avionics to support his claims which led me here.

I know the first thing you might say is that we are on poorly moderated forum - no doubts about that. I am sure "our" troll wouldn't last 24h here.

However things are, as they are, so I ask if there's any assistance you are able to provide? If not, a clear statement from Paul (Overscan) that such thing is impossible could also be of some help.

We have mostly used as "ammunition" "HUD" pictures from the manual and also "HUD" shots from some youtube videos. Cretin stated that HUD and HDD (IPV) show different pictures i.e. (while target is locked on HUD, radar searches on HDD :-X ;D :eek:)

Thanks

It can't be done.

The technical training documents posted on the last page (https://www.secretprojects.co.uk/forum/index.php?action=dlattach;topic=102.0;attach=598409) clearly distinguish between:

1) Finding, detecting and determining the coordinates of targets, maintenance "on the pass" up to 10 targets with the continuation of air space search.
2) Continuous tracking of one target with accurate measurement of its coordinates without overview of the air space.
3) Discrete-continuous illumination of the attacked target with the formation and transmission of radio correction commands.

When you engage tracking mode, you designate the target (or it is autoselected for you), then the radar stops scanning for targets, and focuses purely on the single target. The "on-the-pass" mode simply doesn't give enough detail quickly enough to accurately calculate launch parameters or formulate course correction commands for the R-27R missile.

Now, it's possible that the Ts100 processor could continue predict the other, non-tracked targets motion based on the last known direction and speed, but again the accuracy of these measurements in "on-the-pass" mode is quite low so it would probably not be terribly accurate. The only way to 100% disprove this would be testimony of a MiG-29 pilot or a video showing the radar in operation. I don't think it's likely - I would expect tracking the target gives it quite enough to do for such a relatively crude computer.

Thanks :)

SNP - the closest English equivalent is "escort while pass" - it gives rough position (up to 4 km error as you have said), but deals with closure dynamics - ie: If you have A-10 flying towards you at 500km/h at the distance of 22km and 5km after it B-1B flying at 1020km/h, system shall conclude B-1B shall "surpass" A-10 and shall recommend B-1B for locking up.

"Now, it's possible that the Ts100 processor could continue predict the other, non-tracked targets motion based on the last known direction and speed"

That's the feature of the Foxhunter, I would love very much if you can re-upload mode photos on its page.

The basis of the OEPrNK complex is the S-31 BCVM, which performs mathematical and logical processing of information when solving combat missions, navigation tasks to ensure the combat regimes of the complex and control tasks. It performs the following basic operations: determining the data and conditions necessary for launching guided and unguided missiles, as well as the moment the bombs are dropped during bombing; determination of corrections when firing a cannon at air and ground targets; information processing E502-20; performing calculations related to solving navigation problems for combat modes; providing a mode of interaction with the RLPK complex; control of the complex in flight and at all stages of preparing the aircraft for flight. Communication of the BCVM S-31 with on-board analog devices, systems and multifunctional remotes is carried out through the input / output device UVV20-31, which, in addition, digitally encodes the commands received from the control panels. For communication and conversion in the type and scale of signals and commands that provide communication between the OEPRNA complex and other aircraft systems, the communication and distribution unit BSR-31 is used.
Optoelectronic sighting system OEPS-29 includes a quantum optical positioning station (KOLS) - ed.13C and a helmet-mounted target designation system (NSC) - ed.-Shchel-ZUM "(Щ-ЗУМ). KOLS station, in turn , consists of a survey-tracking heat direction finder (TP) and a laser range finder (LD). The KOLS station provides search, detection, capture and auto tracking of air targets by their thermal radiation in the infrared region of the spectrum, measuring the angular coordinates of an air target, as well as the distance to an air or ground target. KOLS station measures the angular coordinates of the line of sight of an air target relative to the building axis of the aircraft and the absolute angular velocity of the line of sight, as well as the distance to the target at the time of sounding. - Other parameters necessary for aiming, in particular angular accelerations of the line of sight, the current value of the distance to the target, speed rendezvous with the goal, are calculated by the computer S-31.
The NSC helmet-mounted target designation system is designed to determine the angular coordinates of the line of sight of a visually observable target, accompanied by a turn of the pilot’s head, in conditions of close air combat. The NSC system issues to the S-31 digital computer the primary angular coordinates of the line of sight of an air target, according to which the S-31 digital computer calculates the angular coordinates of the line of sight in the aircraft and other coordinate systems and provides target designation.
The navigation system SN-29 is designed to solve navigation problems, continuous automatic detection and delivery to sighting systems, the SAU-451-02 system and other airborne devices and flight-navigation parameters at all stages of an airplane’s flight. Flight and navigation information is displayed and displayed on the indicators of the SEI system and indicator devices - a planned navigation device of the PNP-72 type and a flight control device of the gearbox that are part of the SAU-451-02 system. The structure of the SN-29 system includes: an information system for the vertical and course IK-VK-80-4 (publ. Ts-050), a radio technical system for short-range navigation and landing RSBN with a digital navigation computer (NEC) - on-board radio navigation equipment - BRNO-29 (ed. A-323); system of air signals SVS-II-72-3-2; switching unit BK-55.
The SEI system is designed to indicate and display overview, sighting, tactical and flight-navigation information in all operating modes of the SUV system. The SEI system consists of two indicators: the ILS-31 collimator sight-navigational indicator “on the windshield” and the IPV navigational-tactical indicator of direct vision.
The weapon control system SUO-29M2 provides direct preparation for use and ensures the use of all types of weapons used on aircraft.
Unified multifunctional control panels ПСР-31. PUR-31, PU-47, PU-S-31-1, PVK-31, PK-31 are designed to control the operating modes of sighting systems RLPK and OEPrNA, and the SUV system as a whole.
The PSR-31 special modes console provides: selection of the operating mode of the SUV system, switching on the instrument guidance mode according to the data of E502-20; switching of operation modes of indicators ILS-31 and IPV; management of switching search zones of the RLPK complex and the KOLS station; selection of the launch mode of guided and unguided missiles or the discharge of bombs and other cargo setting the size of the target for external base range measurement and performing a number of other operations.
The PUR-31 control panel is designed to select the operating mode of the RLPK complex. It provides: switching of the RLPK operating modes, control of the radar transmitter; the inclusion of the compensation channel radar; turning on and off the SORT mode; selection of the operating mode of the RLPK complex under the influence of interference; the task of exceeding the target over the fighter.
The PU-47 control panel is designed to select the modes of bombing, the mode of operation for air or ground targets; operating modes of the device FKP-EU; selection of emergency bomb drop.
The PVK-31 input and control panel provides manual input of ballistic data of bombing into the S-31 digital computer, as well as control of the entered information, input and output information from the S-31 digital computer. The control panel PK-31 is designed to control the integrated control system of the OEPrNA complex and its devices and systems. The KU-31 button is used to control the strobe and field of view of the RLPK complex or KOLS station.
Blocks BDLU-31 and BDUS-31 provide measurement, respectively, of the absolute acceleration components along the axes of the aircraft coordinate system and angular . aircraft speeds relative to construction axes.
The FKP-EU photocontrol device is designed to control the accuracy of aiming and documenting the results of firing at air and ground targets. It provides simultaneous and combined photographic recording of targets visually observed in the field of view of the ILS-31 indicator (external space), and parameters displayed on this indicator.
As part of the SUV BTsVM S-31 system, other systems and devices of the OEPrNA complex are functionally interconnected with each other and with the RLPK complex both along the code lines of communication and along the chains of analog signals. Reception and transmission of information over code lines of communication in the S-31 digital computer is carried out in the form of a bipolar 32-bit serial binary code. Information on the following lines is received in the S-31 digital computer: on A2 - from the KOLS station, on A4 - from the NSC system according to the READY signal; on A5 - from the navigation system SN-29; on A6 - from E502-20-04 at the signal 'READINESS I; on A7 - from BCVM N019; on A8 - from UVV20-31; on A9- from the LMS system; A18, A16 - from the SEI system, A17 - from the PVK-31 remote control.
The issuance of code information from the S-31 digital computer to the interacting digital computer, systems and devices is carried out along the following lines: along B1 - to the KOLS station; on B2 - to the NSC system; according to the BZ - to block Н001-25 (left) and then to the SUO-29M system; on B4 - to block Н001-25 (right); according to B5, B6, B13 - to the CEI system; on B7 - in the BCVM N019; on B9 - to the PVK-31 console; according to B14 - in UVV20-31; for B11 - for TESTER, for B10 - for OSVKiPE.
2.1. Quantum optical location station KOLS-29
.
The KOLS quantum optical-location station is part of the OEPS-29 optical-electronic aiming system. The KOLS station is an integrated system consisting of an OSTP survey-tracking heat direction finder and an LD laser range finder. OSTP provides search, detection, capture and auto tracking of an air target in the air traffic control system by its thermal radiation. LD is designed to measure range to an air or ground target.
KOLS measures the angular position of the line of sight of the target (φ y , φ z ), the absolute angular velocity of the line of sight of the target (ω y , ω z ) relative to the construction axis of the fighter and the instantaneous distance to the target. These measured parameters through the block of digital converters BTSP are issued in BTsVM S-31 (Ts100.02-02).
Other parameters necessary to solve the aiming problems (angular accelerations of the line of sight, current values of the range to the target and its derivatives) are calculated in the digital computer S-31 (Ts.100.02-02).
The use of KOLS as part of OEPS-29 makes it possible to effectively carry out targeted firing from a cannon, launch guided aerial maneuvers and short-range missiles, as well as launch unguided rockets and drop bombs to destroy ground targets. Combat application of KOLS is provided at all altitudes of a fighter’s flight, including against the background of the earth, day and night, in conditions of optical visibility, and also in the presence of organized interference.

KOLS station (see Appendix 2) consists of three main functional blocks:
- the head of the target (GV);
- block tracking systems (BSS);
- electronics unit (BE).
All main elements of the OSTP and LD are located in the main body. Structurally, the GW is made in the form of a monoblock, which includes an optical-mechanical unit, as well as receiving and transmitting LD units. The transmitting unit LD consists of a radiation unit (the laser itself), a control unit that provides laser operation in a pulsed mode, and a laser power supply. The receiving unit is designed to receive a laser pulse reflected from the target and convert it into an electrical signal.
Optical-mechanical unit (OMB) consists of the following functional units:
- a coordinator designed to measure the angular coordinates and angular velocities of the line of sight of the target; it includes an optical antenna (scanning mirror), a mirror motion control device, an optical system and a photodetector of the IR channel of the heat finder;
- a scan unit consisting of line and frame scan generators that provide control of mirror scanning in azimuth and elevation in viewing mode;
- a reference voltage shaper intended for generating reference pulses, which are used in calculating the coordinates of the target in the tracking mode;
- a collimator designed to generate radiation of the target simulator in the built-in control mode;
- a block of built-in control of the TLS, which ensures the operability of the angular velocity sensors.
The electronic unit ensures the operation of the LD in different modes with the help of a converter, as well as measuring the distance to the target using a time interval meter.
The block of tracking systems includes:
- a control unit that solves the problems of switching station blocks, passing signals and commands, highlighting mismatch signals in various operating modes, checking the station in the built-in control mode;
- a block of video amplifiers designed to amplify the signal from the output of the photodetector of the heat finder;
- a sawtooth voltage generator, which is used in power amplifiers to obtain voltages that control the operation of executive motors, which ensure the rotation of the scanning mirror in the overview operating modes of the station;
- power amplifiers designed to amplify the voltages that control the operation of executive motors;
- AGC block, which performs automatic gain control by noise and signal; the automatic control device constructively enters the AGC block, which transfers the heat direction finder to tracking mode;
- extrapolator, which generates the mismatch signals that control the operation of the Executive motors in tracking mode.
Functional communications of the KOLS station with the SEI and BTSVM S-31 unified indication system are carried out through the digital converters block, which is not part of the KOLS.
KOLS station has three operating modes: viewing mode, guidance and capture mode, tracking mode
2.2. Helmet targeting system NSC
The NSC is designed to determine the angular coordinates of an aerial visually observable target as part of OEPS-29, followed by a rotation of the pilot's head. The angular coordinates of the target are determined by the spatial position of the line of sight (LV) (line that connects the pilot’s eye with the target). The angular coordinates of the position of the drug with the NSC will be transferred to the “BCVM S-31, where they are converted from the NSC coordinate system to the KOLS coordinate system, and then they are used for preliminary target designation of the RLPK, KOLS and the homing guided missiles.
The principle of the NSC is as follows. On the helmet of the pilot on the helmet-mounted sighting device (NVU) at three points spaced apart from each other at certain distances are the emitting diodes ID1, ID2, ID3. The wavelength of the radiation of the diodes lies in the near infrared (IR) region of the spectrum of the optical range and is invisible to the human eye. Emitting diodes form a plane, the coordinates of the location of the diodes determine the position of the plane in space (Fig. 1). The NVD, on which the emitting diodes are located, is mounted on the pilot's helmet so that the target LV is perpendicular to the plane formed by the three IDs. Obviously, to determine the direction to the target in this case, it is enough to determine the spatial position of the plane, determined by the position of the pilot's head. Therefore, this plane is a reference (reference).
The spatial position is determined in the NSC equipment by the direction finding method of its radiation by two spaced photodetector devices located in scanning devices (SKAB-A and SKAB-B), which are located above the instrument panel of the aircraft cabin. Photodetector devices have radiation patterns that are narrow in the horizontal plane (along the Z axis of the aircraft) and wide in the vertical (along the Y axis of the aircraft).

Fig . one

Fig .. 2
These radiation patterns (MD) rotate towards each other in the horizontal plane (Fig. 2, top view).
When the bottom of the photodetector passes through the ID, its radiation enters the photodetector, the output of which in this case is the signal from this ID. Since the scanning speed of the bottom of the receiving antennas is known, then, knowing the time of the start of scanning and the time of arrival of radiation from the ID, it is possible to determine the angle (bearing) at which the emitting diode is "visible" to this photodetector. The bearing on the second ID and another photodetector is determined similarly. As a result of the direction finding of the ID by two photodetectors, a line directed parallel to the Y axis of the aircraft on which this ID lies is determined. The length of this line is determined by the width of the bottom of the receiving devices in the vertical plane and the distance between the ID (pilot’s head) and SCAB. Direction finding of the other two IDs will also produce two lines parallel to the Y axis of the aircraft. In this way, as a result of direction finding by two photodetectors of three IDs, three lines are obtained parallel to the Y axis of the aircraft, the spatial position of which is determined by the spatial position of the ID, i.e. turning the pilot's head (Fig. 3). These lines are the geometric location of the ID location points. Since the distances between the ID location points on the NVD are known, then regardless of where the ID will be on the line, they will form planes parallel to each other, and the direction of the perpendicular, i.e. LP of the goal will be one and the same. Since the distances between the ID location points on the NVD are known, then regardless of where the ID will be on the line, they will form planes parallel to each other, and the direction of the perpendicular, i.e. LP of the goal will be one and the same. Since the distances between the ID location points on the NVD are known, then regardless of where the ID will be on the line, they will form planes parallel to each other, and the direction of the perpendicular, i.e. LP of the goal will be one and the same.
The NSC provides, under conditions of visual visibility of the target, the delivery of drug coordinates in the area corresponding to the cone (Fig. 4) with a flat angle at apex of 60 ° in an aircraft coordinate system, limited in elevation to - 15 °.
The NSC's operability is ensured by moving the NVU unit (pilot’s head) in the zone shown in Fig. 5.

Fig.5
The maximum error in calculating the coordinates of the spatial position of the drug is 45 ". Power consumption on the DC circuit +27 V is not more than 150 W; power consumption on the AC circuit 115 V frequency 400 Hz is not more than 250 VA. Weight of the DUT is not more than 0.35 kg; the mass of the NSC is not more than 10 kg, the time the NSC is ready for operation from the moment it is turned on does not exceed 3 minutes, the time of continuous operation is 3 hours, the minimum break between cycles of continuous operation is 25 minutes.


The NSC includes 4 blocks:
- Helmet sighting device NVU;
- scanning device - SKAB-A scanning unit;
- scanning device - SKAB-B scanning unit;
- electronics unit (BE).
In the NVU block are located: emitting diodes IDi (i = 1,2,3), which form a reference plane; sighting device consisting of a collimator device and a reflector (retractable translucent mirror); photodetector of the device for automatic brightness of the luminance of the aiming and signal brands.
IDi emit energy in the form of a continuous sequence of pulses of duration I μs and with an interval between pulses of 9 μs. The pulse sequence emitted by one diode is shifted relative to the pulse sequences of the other diodes by 3 μs. The shift is necessary for the selection of pulses of various diodes in the BE. The radiation patterns of IDi are so wide that the radiation of each IDi falls on SCAB-A and SCAB-B.
The collimator device included in the sighting device is intended for the formation of sighting and signal marks. The aiming mark (Fig. 6) consists of two concentric rings, which are formed by illuminating the aiming grid with an incandescent lamp (L1). The signal mark (Fig. 7) is a crosshair with a gap in the center, which is formed by illuminating the signal grid with an L2 incandescent lamp. The radiation of the lamps L1 and L2 pass through the grid and enters the input of the collimator. Aiming and signal marks are highlighted in yellow. Combinations of illumination of the aiming and signal marks form one-time commands for the pilot.
Fig. 6 Fig. 7
The reflector (retractable translucent mirror) is designed to enter sighting and signal marks into the pilot's eye. The reflector is reclined (introduced into the field of view of the eye) by the pilot by pressing the reflector input button in the SUV-29 HELMET operating mode. The position of the reflector in the tilted state is adjusted so that the target's LV (the line connecting the pilot’s right eye with the target) passes through the center of the aiming mark.
The photodetector for automatic brightness control is a background light level sensor. Depending on the illumination of the background, the brightness of the glow of the aiming and signal brands changes (power supply of the lamps L1 and L2). The higher the background light level, the brighter the lamps L1 and L2 should glow, and vice versa.
SCAB blocks are identical. SKAB includes an instantaneous field of view (MPZ) driver, an optical monoblock, an amplifier of the main channel, a tracking device, an amplifier of reference (single-degree) and reference (thirty-six-degree) pulses. The instantaneous field of view (radiation pattern) of the photodetector (FP) is formed by a ten-sided mirror prism, the rotation of which by the motor (D) through a gearbox with a reduction coefficient i provides scanning of the photodetector MPZ, and an optical monoblock (lens). The scanning period of MP3 by each face of the prism is 10 ms ± 20%.
To determine the spatial position of the MPZ in the scanning area, a tracking device is used. The tracking device consists of a movable upper limb, mounted on the same axis with a ten-sided prism, and a fixed limb, rigidly fixed in the SCAB housing. Transparent strokes are applied to the limbs, following after one degree and after 36 degrees. The limbs are set so that the 36 ° strokes correspond to the moment of the beginning of the MPZ scanning by each face of the prism. Photodiodes (PD) are fixed above the movable limb. When the strokes of the rotating and stationary limbs coincide, light pulses will arrive at the PD. At the moments of the PD, voltage pulses appear, which through the amplifier of one-degree and thirty-six-degree pulses arrive in the BE, where they are used to determine bearings on the emitting diodes IDi (i = 1,2,3).
2 . 3. Brief description of the BCM Ts.100.02.
BTsVM Ts100.02 is executed on the main module principle. The operation of the computer blocks is carried out at two levels - software (operator) and microprogram.
Element base of a digital computer: main (silicon integrated circuits of the 134, 133, 136, 130, 106 series, which are potential systems of elements with transistor-transistor logic (TTL), which are based on the AND-NOT / OR-NOT logic circuit); special elemental base, providing communications both between the elements of the digital computer, and between the digital computer and external devices and systems.
Cooling of the ЦВ100 TsTSVM is carried out by forced ventilation with a cooling air flow of 10 kg / h at a temperature of T = 20 ° C and an ambient temperature of 20 ° C from an air conditioning system that is not part of the BTsVM.
The composition of the digital computer Ts.100.02 includes: A09.030.02 device, designed to perform computational and logical operations in a program or circuit way and exchange information with external sources and consumers of information; unstabilized rectifier 09.084 (VN) and harness 09.086-01. The device A09.030.02 can operate without forced ventilation for no more than 10 minutes at an ambient temperature of no higher than 60 ° C. Unstabilized rectifier 09.084 allows continuous continuous operation in conditions of natural cooling at an ambient temperature of no higher than 60 ° C. With the cooling system turned off, i.e. in conditions of natural convection, a digital computer can work for a strictly limited time (see table 2.).

4. Product C-31 - troubleshooting.
Troubleshooting of the S-31 product on board is carried out using the integrated control system of the complex without connecting test equipment.
In flight, information about complex failures generated by the built-in control system with the participation of a digital computer is transferred to the Ekran product and stored. Separate failures are indicated to the pilot on the Ekran product in the form of frames with the names : CBC, TWO CURSOVERTIK, CALCULATE NAVIGATS, BASIC CURSORVERTIC, RESERVE COURSEVERTIC, SUA, GUN, HELMET, S-31.
The information on failures stored in the flight after the end of the flight is documented on the screen of the Ekran product in the form of numbers assigned by the fixed failure and the time of their formation in flight. Documentation on the film of the Ekran product is allowed; numbers 206 (БЦ0), 207 (БВЦ), 211 (ИЛС), 214 (УВВ), 235 (ШИНА1) are not complex failures. In this case, in the absence of the pilot's comments on the operation of the complex in flight, their analysis is not performed.
In the case of receiving comments on the operation of the complex in flight and in the presence of recorded failures of the S-31 product on the film of the Ekran product, the operation of the S-31 product in the ground-based control modes is checked and troubleshooting is performed.
Checking and troubleshooting of the complex, including its communication lines with the on-board equipment E-502-20, A-037, (A-031) blocks H001-25 and product H019, is carried out using the product "Screen" in pre-flight preparation mode (software control ) object

When troubleshooting and troubleshooting the complex (without covering the communication line with the on-board systems), it is checked in the "VSK S-31" mode
When conducting troubleshooting and troubleshooting of product 915, the complex is checked using the Ekran product.
After checking the complex in the "VSK S-31" mode, if the system detects integrated failures and malfunctions, the READY display on the PC remote control does not appear. Further troubleshooting is carried out using the remote control PVC. To do this, after the end of the “VSK S-31” mode (cessation of the READY display flashing on the PC), the following are installed on the PVC: switch S-31 - SK-1-SK-2 to position S-31, the MODE switch to the ENTER position. Moreover, on digital indicators No. 1-8, shown in the figure

Thanks Overscan for sharing this manual.
Actually I manage to read this in Russian language somehow (I am from Poland. Polish language has some small similarity, and fortunately I was forced to learn Russian when I was child - (this side of curtain ;) ). At least now I can read cyrillic

Anyway, this post enhance me to find another manuals online.
I found forum with many links:
https://www.mycity-military.com/Avijacija-i-PVO-2/MiG-29-Fulcrum-tehnicka-dokumentacija.html

So I dig further:

There are many known references from airwar.ru etc. Also manual for EKRAN - onboard diagnostic system used in Mig-29 (and in Su-27?)

But I found the whole book from 91 year for Mig-29 electronics. Of course in Russian. Maybe Too much for translation..
