What is the landing speed of a A380?
An A380 crosses the landing threshold at a docile 140 knots and touches down, depending on its landing weight, at a speed as slow as 130 knots, about the same touchdown speed of some corporate jets that weigh 1/50th as much as the world’s biggest airliner.
Do passenger planes have air brakes?
Virtually all jet-powered aircraft have an air brake or, in the case of most airliners, lift spoilers that also act as air brakes. Many early jets used parachutes as air brakes on approach (Arado Ar 234, Boeing B-47) or after landing (English Electric Lightning).
What is a speed brake on a plane?
Speedbrakes are high drag devices that are fitted to almost all high performance military aircraft as well as to some commercial aircraft types. In most cases, speedbrakes are fuselage mounted panels which, when selected by the pilot, extend into the airstream to produce drag.
What do the ailerons do on an Airbus?
The ailerons, along with the spoilers are configured to act as lift dumpers on touchdown in most of the newer Airbus aircraft. This was introduced in the Elevator Aileron Computer ELAC standard L96, where, Aileron up deflection at ground spoiler extension becomes basic function.
Do you only deflect the ailerons up for landing?
Steve is right on. Only deflect the ailerons up for landing. You will likely need just a bit of up elevator mix. Note that you do want the nose up slightly to bleed off the speed. Always test at altitude first. Ideally, you want to use the flap stick or other variable input so you have full control over the landing.
Can you put both ailerons up in an elevator?
You can put both ailerons up which will act as brakes but DO NOT put both down, this will result in it a tip stall pretty quickly. As for how much elevator compensation that’s something you’ll need to try for yourself as it will vary according to your set up but for starters I’d try adding a little up elevator.
When to use ailerons up or down on a F5D?
Ailerons up will cause nose down requiring some up elevator, and oppisite for flaps. Spoilerons are very effective to slow down my very slippery F5D airframe. As was said, don’t use them in a turn, only on straight, final approach.
