Could it be that the MiG flaps control has been affected? I notice that they cannot be released to their pre-set limit. instead, you can only fully retract them by setting the pre-set to zero. If, for example I set the limiter to 60 degrees, and try to retract them, they stay down. if I adjust the limiter to 30 degrees, they fully retract while adjusting, and then drop to 30. pressing retract does nothing. Can anyone else verify?

The limiter only stops them extending past a certain point.  It does not stop them while retracting but you should not be able to go past the limiter anyway. 

If you set 30 degrees then a single press on 'Lower Flaps' will drop them to 30.   If you want to go to 60 then you must hold the 'Lower Flaps' button to move the limiter to 60 but the flaps should stay at 30 until you hit the 'Lower Flaps' button once.      If you want to fully raise the flaps while they are at 60 then a single key press should raise them all the way.  If you want to change from 60 to 30 then you hold the 'Raise Flaps' ket to move the limiter to 30 and the flaps will move at the same time.     I will check if something has changed. 

 

 

 

EDIT 2
It looks like this changed around July 2019 and was deliberate.

 "MiG-3 flaps have been corrected - any change of the flaps limiter position retracts them first and then extends to a new position;""

 

I am a little confused as that seems to make them work no differently to any other flaps i.e you must hold the key to lower the flaps to the required position.  The only difference is that they don't retract smoothly and instead go full closed then drop again.  That sounds stupid and potentially dangerous. Why would they want that?

I've checked right now. It works as it should:

 

Flaps limitercan bhe adjusted only when flaps valve is set to "retract".

So you can move your limiter up or down only if flaps are pressed up.

 

Due to this it looks like:

 

Flaps are retracted, limiter at 0%. You want to extend flaps to 50%:

- Holding F key. Flaps are pressed up. Limiter wheel is rotating, limiter is extending gradually to 50%.

- When limiter reaching 50% you releasing F key. Limiter wheel stops, flaps valve sets to extend position, flaps are pressing down. If speed is low and flaps are not pressed bi airflow than flaps are pressing down to the 50% limit.

 

Flaps are extended and at 50% limiter. You want to extend them more to 100%:

- Holding F key. Flaps valve set to retract, flaps are pressed up. Now limiter can be adjusted, it rotates down to 100% position.

- Limiter reaching 100%, releasing F key: flaps valve set to extend, flaps are pressed down to 100% limit.

 

Flaps are extended and at 100% limiter. You want to retract them till 50%:

- Holding LShift+F key. Flaps valve set to retract, flaps are pressed up. Limiter rotating up to 50% position.

- Limiter reaching 50%, releasing LShift+F key: flaps valve set to extend, flaps are pressed sown to 50% limit.

 

So once again - while at real plane the operations with flaps limiter wheel were prohibited while flaps are not pressed up - this kind of flaps operation algorythm is valid.

 

Somebody please be kind to an old man and explain what Han is saying.

I have tried what I *think* he is saying and it makes no sense.  For brevity I will use 'Up' & 'Down' for lowering & retracting flaps.

 

Starting with flaps up and limiter at 0.

If I hold 'UP' then hold 'Down' at the same time the flaps stay up while the limiter moves to 30 then when I let go of 'Down' the flaps drop.

If I *don't hold 'UP' I get exactly the same result.

 

Now the limiter is at 30 and I want to full extend my flaps to land

I hold 'Up' and press 'Down' and the flaps fully retract while the limiter moves then when the limiter has gone as far as it can I let go of the key and the flap drop all the way.

Do the same without holding 'Up' and you get exactly the same result.

 

Now the flaps are fully out and the limiter is at maximum but I only want 30

If I hold 'Up'  the flaps fully close while the limiter goes to 30 then when I let go of 'Up' the flaps drop to 30.

 

This cannot be how it is supposed to work.  It is crazy. 

You are on finals with half flaps and decide to lower them further and the plane raises your flaps fully while you move the limiter then drops them suddenly!!

Alternatively you are on finals with full flaps and decide that is too much and you only need half flap,  the plane takes away all your flaps then drops them half way.

Either scenario could cause a disaster on finals.

 

Am I being stupid?
