Adding Trailing Edge Flaps, with or without gear

[Tchalla]

Can't find anything in previous topics, did they change the pitch characteristics when flaps are added? Seems like when you are at high or low speed the pitch up and down authority is reduced since 2 updates ago.

How (and why) do you extend the trailing edge flaps manually?

 

The ~50% reduced pitch and roll authority due to the extended gear (which is incorrect since it should depend on the gear lever position) is there since the first release version.

How do you extend the trailing edge flaps manually?

 

 

Flight Control Panel (back left) Alt Flaps switch to Extend.

Landing Gear failure to extend for whatever reason to assure you are getting the flaps down for lower stall speed in case you have to land with gear up.

Thanx for the info. But this only applies if there's no approach end arrestment is available.

 

The FLCS takeoff and landing gains are in this case correct since the triggers are:

 

landing gear lever DN

alternate flap switch EXTEND

air refuel switch OPEN

To be exact...with gear HANDLE up. When the handle is down the Flaps will come down.

They will only extend below 400 knots for alternate flap switch EXTEND and air refuel switch OPEN

If all gears do not come down an approach end arrestment is not recommended. Just land gear up, and if the handle remains up you have to select ALT flaps.

Just re-read the procedure and you are of course correct.

No other reason other than what's been said above. But the real fun begins when you lock the leading edge flaps with malfunction.. noticed the damage model has included instability with them missing.

Well asymmetry brakes "should" handle that for you automatically if it is a really bad malfunction but yeah if something happens to the LE Flaps best to lock them out and just deal with whatever position they are in less it gets worse.
