AOA for Landing

[arriflex]

What AOA should I be aiming for on approach?

** depends on speed, and once BLC works, AoA can be reduce by 2-2.5 deg

Note that the MiG-21 does not make its approach to the runway at a constant speed or AoA. Russian procedure is to keep reducing speed from the turn to final or so, all the way to touchdown. When you get to the runway, pull the stick to stop your descent just above the ground, throttle not to IDLE, but to MIN (if you retard the throttle more than that, you will lose a lot of lift because of the BLC), and let your airspeed go down. Keep on pulling gently on the stick to touchdown with the stick very much aft and at 260-280 km/h.

 

That's what the manual says.

Thanks!

I didn`t knew BLC looses lift od idle..

 

It should be noted in the manual with big,red letters.

 

Maybe that`s why I`m landing 20% of times without damaging the AC...

There's actually a label on the throttle for landing power setting (LND in English pit).

9-10 degrees AoA with BLC, 11-12 without. Page 54 of the real manual IIRC.

BLC takes bleed air off the engine, so the engine must be producing sufficient thrust for it to function correctly.
