Stick Pushers
 

I have heard some conflicting reports on the reasons why some manufacturers choose to outfit their aircraft with stick pushers. I am aware that some aircraft have pushers while others don't. Does anyone have background information as to the certification process, and/or requirements that mandate some aircraft to have them (Gulfstream) while others do not (Falcons)? I'm curious to hear your thoughts on this subject, and specifically, if an aircraft has a stick pusher, does that mean it has an inherant design flaw if allowed to approach a deep stall condition? Thanks in advance.

Falcons dont stall.

I certainly wouldn't say "design flaw"....swept-wing jets don't tend to aerodynamically react well to a wing stall, and my guess is how a particular wing & aircraft behave in full stall is how some end up with pushers while others do not.

My understanding is that with Transport Category aircraft with T-tails require a stick pusher due to the possibility to enter "deep stall conditions."

When they put delta fins on the 55C which morphed into the LR60 they realized that the deltas helped to pitch the nose down and they took out the stick pusher. They also took away one yaw damp and allow us to dispatch without it at all, unlike the LR series.

Can't comment on other T-tails

Fly By Wire and stop worrying about that 1980 crap.

:)

Yea... hey, just engage the autopilot and forget about it. Good answer :rolleyes: Or pretend you're flying and the wire is not there... hmmm.... good ol days when we used to fly.... back in the crap 80's...

Who said anything about Autopilots?

I hand fly a brand new FBW plane far more than I ever flew a 1980s POS
Learjet....
