Cross control on Airbus
 

Is it possible or is it just not recommended to do cross control on airbus fbw?

If so, can anyone tell what is the reason behind it?

Thanks.

Yes it is possible. As for why it is not reccommended, I don't know.

Greetings,
Theoratically you cannot cross the controls, however, like someone pointed out you can by ordering a roll, release the joy stick then apply opposite rudder, the problem is that there will be too much stress on the fin :ok:

If you're trying for a wing-down method crosswind landing you don't need hardly to cross control. Add downwind rudder and the upwind wing will miraculously and proportionally come down without pilot intervention. I don't know why it works, but it certainly seems to. Ask Toulouse :)

Hi Aikon,

It may be that the control laws have been modified since I last flew the A320 in 2001, but I never experienced the automatic sideslip that Cardinal describes above.

See if this − and posts from many contributors on the same thread − make any sense:

I’m referring particularly to the paragraph “Crosswind Landing”. Prolonged flight in sideslip may not be practicable or desirable on FBW Airbuses, probably because of the roll-yaw coupling feature.

Hmm, I seem to recall Airbus changing certain regs and advisories following an accident involving crossed controls and a damaged tail fin? That's about all I can remember, can anybody shed more details?

Thanks guys. It is much clearer to me now. This is such a wonderful forum where a lot can be learned from each other.

And a special thanks to Chris for pointing me to an excellent thread with so much info.

Well done guys!
