X. PRECAUTIONS AND TECHNOLOGY piloting aircraft MiG-17P
440. The MiG-17P is a modification of the production aircraft MiG-17, and differs mainly in that the MiG-17P radar scope RP-1, which provides execution of tactical tasks day in bad weather and at night and adverse weather terms.
441. Preparation and testing of aircraft and engine flying in front of the sequence set forth for the MiG-17. You also need to look mount and check for cracks on the fairings and the sighting survey station antenna RP-1.
CHECKING radar sight RP-1 BEFORE FLYING
442. pilot test use of RP-1 on the ground in the following cases:
- If at gunpoint to remedy the faults detected in the previous flight;
- If the flight was preceded by a 100-hour maintenance work with the removal of the main blocks of sight from the plane.
In other cases, the pilot checks the units sight only by inspection.
443. before checking on the ground radar scope RP-1 is necessary:
- Make sure that the switch is "Day and Night", located on the cable box in the upper section of the forward fuselage, placed in the position corresponding to the time of day;
- Check the network connection aircraft external power supply;
- Make sure that the "Station-off", located on the remote control is set to "Off", and the handle brightness "Bright", located in the lower right corner of the indicator housing, is set to the left (the brightness has been removed).
444. To test the RP-1 pilot must:
1) Turn on the sight. 2-3 min. after turning on the display screen appears raster line noise and electronic attitude indicator.
2) To secure control handles "Bright" and "Fok" get on the screen of a weak, but clearly the presence of background noise from luminance noise in the failure zone of 2 to 5.6 km.
Start noise should be at a distance of 0.2 km, and the upper limit should be placed on their range of 12 km and more. Noise azimuth should be restricted zone of 60 ° to both sides of the zero azimuth.
After turning on the scope of RP-1 needle on the control panel should initially vary between 0-200. After 3-4 minutes. after the arrow should be set to between divisions 60-220, making variations of not more than 10 divisions, and in sight with a new scheme AFC hand 3-4 minutes. without hesitation is immediately between divisions 50-300.
3) Check the current 1 crystal and the pressure in the waveguide system, for which the switch "Current 1 cristae. - Pressure" set to "Current 1 cristae." Needle in the normal current of one of the crystal must be between 60-220 divisions, then switch "Current 1 cristae. - pressure" switch to the "pressure", with needle should be between 80-140 divisions.
4) Check the sighting of the RP-1 by pressing the "Control", with intact its work should observe the following:
- The overview display at a distance 600 m mark appears as a horizontal objective stroke, and below it - in the form of line capture bright line, mark targets smoothly moves to the right and stops at the right edge of the square area of sight;
- On the reflector unit data appears artificial light target image, whose brightness increases as you move it from the initial position to the right upwards, with an artificial target image size increased to a size corresponding to the range of 600 m;
- After releasing the "Control" for a second artificial target image retains its size and brightness, and then returns to its original position, reducing its size and brightness.
Make sure the Internet sight, turn it off.
WORK pilots with radar sight RP-1 IN FLIGHT
445. Enabling the radar scope of RP-1 and prove that it works in the air produced in the same sequence as in the verification on the ground.
After 3-4 minutes. after the crosshair on the display screen at a distance corresponding to the height of the flight, the signals appear altimetrovye land in the form of bars and spots. With increasing altitude terrestrial interference decrease; at 7000 m , they almost disappear.
At altitudes below 3000 m observation marks goal against interference from the ground is difficult, resulting in operational use is limited scope minimum height of 2500 m
After 5-6 minutes. after the scope and level flight mode to check the position of electronic artificial horizon line guidance with respect to the line of banks and if necessary adjust their relative positions, mode and level flight at the same check on the flight and navigation instruments. Small aircraft evolutions make sure that the operation of the electronic artificial horizon.
446. Continuous monitoring of sight in the air is by the presence of noise in the overview display and the current one, as indicated by the crystal. Off sight RP-1 is performed before planting.
447. After turning sight RP-1 to the moving part of the indicator tube to remove from itself the way.
