| Hey,
|
| Some of you may have heard of Air Canada 143 [http://www.youtube.com/
| watch?v=dfJIpA2gv1g] which ran out of fuel in mid air and had to make
| an emergency descent at velocities way above the normal limits. The
| pilot's makeshift technique was to engage a sideslip to decelerate the
| aircraft (which by then had no flaps, and only minimal hydraulics).
|
| Now I thought that sideslips (and crabs--whatever the difference
| between the two is...) were only to be used to handle crosswinds.
|
| They're different and they aren't just used for crosswinds.
|
|
| I
| didn't read anywhere that they could be used to bleed excessive speed,
| although it makes sense from an aerodynamics perspective. Anyone out
| there used sideslips for anything other than crosswind approaches?
|
| PS: I have read about many cases of jetliners that had to make
| emergency descents at abnormally high speeds, but the AC143 seems the
| only one to have used the sideslip.
|
|
|
| it isn't.

Didn't think so.
