Emergency Descents

But as @dmspilot indicated, the expectation of the ACS still isn't a spiraling descent. The bank angle is only required to "maintain positive load factors" during the initial pitch down...in other words, get the nose down quickly without negative g's. Once the nose is down, the expectation is wings level or normal turns, as clearly indicated by the AFH.
Yeah. They aren't trying to squeeze every last FPM they can out of the manuever. Probably best that way for PPL.
 
So how did you do it? You dont have flaps, right? Is it an RG? Straight ahead or bank? How much?

Straight ahead. No flaps. Can't maintain that angle for long though. Maxed out at 160 in the pullout. A more shallow pitch angle with a bank would probably be the best approach.
 
An emergency descent also comes in handy when passengers had bad Mexican food the night before.

Emergency Venting procedure is a little further back in the POH:D

My instructors exact words were "this airplane has failed you. It's trying to kill you right now. You owe it nothing."

That or "Insurance just purchased your aircraft - only concern now is no injuries"
 
how about a controlled spin to 1000ft agl and than proceed at just under vne to your determined landing area than flaps slip and pray
 
Not quite steep enough. The steeper you bank, the faster you come down. May have affected your comparison numbers. When I teach the spiral-down, full flaps, Vfe method, I'm looking for at least 45 degrees of bank. The rate of descent increases dramatically over the last 10 or 20 degrees. >2500 fpm down is not unusual in a 172 or 182.
True. We didn't want to go overboard on the first try so we'll need to revisit with a steeper bank.

Oh wait, spins...we don't teach that anymore...sigh.
Neither do they teach stalls. Cuz spins and stalls are the most frequent killers. So we eliminate them. What becomes the #1 killer now? Landings. So we should logically eliminate practicing those too, right? :D
 
Just adding a minor note about retracts... know your gear system... and why Vle is at that speed.

In a lot of aircraft, Vle is set at a speed that either the hydraulics can’t overcome to get the gear down and locked, or a speed that’ll rip things like doors off, but the gear is just fine.

In a real emergency descent, if the system you have and have studied is limited because say, the nose gear can’t come down against the force of the air above Vle, and you’ve got the gear down and solidly locked... exceed Vle! As long as you know it’s not a locking pin or mechanism limit.

Or if it’s just going to rip the doors off, get on with it. Get down.

Reasons to study your systems for $500, Bob... ;)

Obviously in the training world, don’t be ripping doors off. People won’t like that. :)

But THINK about what the actual aircraft can accomplish ahead of time if you need it to, to survive.

If you’re not bore sighting an airport and you’re landing out in the weeds anyway, no point in saving the gear doors to make it all look pretty when it’s towed out of the field. :)

This is true, and why many larger airplanes have a separate Vle vs Vlo.
