Aileron into the wind question.

Recommended Posts

Hi,

i´d like to know until which speed i should set ailerons into the wind on a, let´s say, 20 knots crosswind. I think it should be until 100 knots ground speed on landing, and from 120 kts on takeoff.

Thanks!!

Use aileron into the wind to keep wings level- as your speed increases, you'll need less correction. Just keep the wings level :)

You will need a little bit of into wind Aileron through out the whole Take-Off, the amount you need decreases as the speed increases. The idea is that you keep the wings in a level attitude and use the Rudder to counteract the Yaw effect.

Or C: Begin the roll with the ailerons "approximately centered" and then ADD as necessary to keep the wings level.

 

The spoilers come up if you displace the yoke about 2 units. I don't really notice much roll until rotation and liftoff.

 

Don't do a Cessna takeoff with the ailerons fully into the wind and then gradually removed.

Obviously put some aileron in the wind to keep the wings level. Don't go beyond 2-3 units due to the fact that the spoilers will deflect. This makes the probability of a tail strike even higher (the spoilers creates drag thus needing more elevator input upon rotation and decreasing tail clearance). After rotation gradually increase the aileron input to keep the wings level! (ofcourse this is real world practice, but this might be adding in the "as real as it gets" thingt...)
