Alfa Posted January 20, 2007 Posted January 20, 2007 Maybe they are just for testing. LSO's screen is black and white anyway. No, like Black_Hawk mentioned, the Su-33 has them too :) : They serve an operational purpose in connection with the carrier line-up system. - JJ. JJ
Kusch Posted January 27, 2007 Author Posted January 27, 2007 You have a point Jens, I just haven't actualy gone to deep into this. I'm interested whether the 311 is airworthy. It has much more naval experience on Kuz than the 312 but only the second prototype is shown on airshows and is known to take part in different weapon and system tests. From these pictures we see some upgrade of the 312 is going on, while the 311 seems to be unused. I suppose the 312 takes major part in the indian MiG-29K developement but it sounds trange when they have two prototypes of the same airframe they use only one. May be there's a good reason why the 311 doesn't fly(or may be it flies but we just don't know that), I would like to know more about this. Yeah that is a good question Tito - I haven't seen any pictures of the 311 flying recently either, while there are lots(including videos) of the 312 flight displays :) . I wonder if the 312 has the new digital fly-by-wire control system installed - I suppose it would have to if test flying it should make much sense in connection with the development of the new 9-41 version for India. As you can see the 312 has been re-fitted with a newer "SMT-style" cockpit, while the 311 retains the old one, so perhaps it also retains the original analogue FBW system. But it doesn't explain why the 311 doesn't seems to be used for tests.......maybe MIG feel they only need one prototype for the purpose :hmm: . - JJ.

Force_Feedback Posted January 27, 2007 Posted January 27, 2007 The lights are there because the onboard laser/radar system compares its current glideslope with that one for the carrier landing pattern, so when doing an automatic approach, the light should be green most of the time, but when doing a mnaual, the LSO can see wether the plane is on, below or above glideslope. And according to that he can decide wether to bolter or not. Creedence Clearwater Revival:worthy:

That makes more sense- testing new flight and engine controls(may be the new digital FBW and FADEC) and aircraft performance on one plane and new avionics/weapons on another. But it still odd why there haven't been any photos of the '311' flying, it doesn't fly at airshows neither. "See, to me that's a stupid instrument. It tells what your angle of attack is.
