Falcon 7X landing characteristics
 
can anyone tell me what the 7X is like to land, especially in a strong crosswind, compared to say a Citation X or Sovereign both of which can be a bit of a bitch.

Thanks

Its very easy to land in normal conditions.
I've not tried strong crosswind landings yet(new on type).
there is a software upgrade that increases the crosswind limit, the rudder is rather small and the rudder steering is getting used too(back to the C152 days).
Will keep you informed.

like all the Falcon type, wings straight and upon landing opposite rudder and little stick in the wind to compensate the induced roll (if you've seen the main landing fairings I'm sure you undersand)..

The 680/750's are well reported as being a handful in a xwind. Cant comment on the 750 but as far as the 680 is concerned compared to the "wider stance" 500's it can be a bloody handful more so when gusty rather than a stiff x-wind.

HD - you skygod you!!! :ok: :}

Hmmm.
Not sure about that "like other Falcons" JR.

The CODDE 2 actually states in the Normal Operations - Special Procedures - Weather - Crosswind:

Note: When the nosewheel is on the ground, the sidestick roll command should not be positioned into the wind.

and

Commanded roll into the wind would increase adverse "weather vane " effect.

If you look at the FCS synoptic page on the ground and command a roll, you will see the rudder deflect in the direction of the commanded roll to keep the turn the system assumes you are making coordinated. However if you're on the runway, it just weathervanes the aircraft. At max crosswind, directional control may become difficult. Its not the best feature of the aircraft. It'll get fixed eventually, as its a software fix.

It also says max bank angle 5 degrees down to touchdown.

Counter-intuitively its the wing tip which will hit first, not the gear door. That is caused by the pitch attitude at touch down which puts the tips closer to the ground.

whatever...just giving you a 500 hours on type practical point of view...for the fairings we've seen what it does trust me...but like other I don't sleep with codde 2 !:ugh:

HD - you skygod you!!!
Thought you would never recognize it.

Honestly now, I think the airplane is quite controlable even in very gusty winds.

Sorry for the thread drift.

Thanks Max, makes sense, no crosssed controls then?
