[QUOTE="Adam106, post: 133032, member: 7932"] Yeah thanks, I've seen the first of those flight global articles, but not the second. Interesting. I was typing from memory with the FIN 1010 thing, so I'm not surprised I got that one wrong. Zoom into the picture of the HUD control panel in the first link you gave and you can see that the HUD modes are listed as: V/STOL, Lnch, Gen, A/A, Toss and Rev. I guess [i]Lnch[/i] is missile (Aim-9) launch, [i]Gen[/i] - General (navigation??), [i]A/A[/i] - Air to Air - Guns mode maybe, with Continuously Computed Impact Line, since missiles would presumably be fired in Lnch mode? [i]Rev[/i] - HUD would maybe show reversionary data, ie basic heading and attitude information from the master gyro without NAVHARs processing (or a from standby attitude indicator?) [i]Toss[/i] - Toss Bombing - Can we differentiate between TOSS and LOFT? Are they one and the same? [i]V/STOL[/i] - Provides a turn and slip ball type indicator for hovering and transitional flight at the bottom of the HUD, with maybe nozzle position? There also seems to be a standby sight option – just a reticule, probably depressible in the event of HUD computer failure. Alas no CCIP or ‘planned’ mode is evident here – I think you’re assessment of the Sea Harriers intended role and original numbers (3 operational Squadrons with 5 aircraft each, I think) might mean the Attack capabilities were indeed limited, at least in the early eighties. The only way to know for sure would be first hand evidence from air crew or an engineer I guess. There's not much else out there..... [/QUOTE]
