PTS standards for accelerated stalls?

[AirBadger]

Anyone know what the PTS standards are if any for an accelerated stall? I can't seem to find any.

I don't believe accelerated stalls are demonstrated stalls.

"maintains a specified angle of bank not to exceed 20 degrees, +/-10 degrees, in turning flight".

Not accelerated a lot, but technically an accelerated stall.

Fly safe!

Where does that come from? Not in any current PTS that I know of.
Oh! You are quoting the part under normal stalls about turning. Duh, I get it.

Accelerated stalls are trained but not tested for certification. The nearest thing to an accelerated stall is on the CFI ASE test "Secondary Stalls" (Demonstration) A/O XI, Task F.

Accelerated Stalls could also be tested orally under A/O II, Task I: FARs and Publications. This is because they are described in the Airplane Flying Handbook (page 4-9).

A CFI applicant should have knowledge of material in the FAA publications, especially the Airplane Flying Handbook, and be able to locate that information for reference.

That was easy, push the button.

Rubbish - as pointed out above, any stall with bank angle is an accelerated stall. The PTS includes information on stalls in the turn.

Yeh - not very exciting accelerated stalls, but accelerated none the less....

I think the commerical requirments (could be wrong) require the CFI only demonstrate an accelerated stall to the applicant. Something like doing a steep turn and begin pulling back until you get a drop. They may aslo ahve to show the applicant a cross-controlled and elevator trim stall as well. I dont think any are called for specifically during the checkride.

All the accelerated stall does is demonstrate to the student that a stall can occur at speeds higher than published 1G stall speeds. That stalls can occur at much higher speeds than you might normally associate with slow flight.

Rubbish - ..

Rubbish?!!...I've heard that tone before, old folks use it when some young whippersnapper starts talking like he knows what he's saying when he really doesn't have a clue.

Well, how 'bout this one, sonny: The mere fact that an airplane is banked does not, in and of itself, create an accelerated stall.

A normal stall (published stall speeds) is achieved when the angle of attack is increased at the rate of 1 degree per second or a rate that produces 1G.

When you are in a level turn holding altitude, you are increasing back pressure (or angle of attack), creating an increase at a greater rate than 1 degree per second or greater than 1G. That's what causes the stall speed to increase.

An accelerated stall is with a greater load than 1G. That's why a rapid increase of angle of attack in a steep bank, an abrubt pullup, or other "abrubt" maneuvering is the way it is described in the Airplane Flying Handbook.

When you make a climbing turn, do you abrubtly increase back pressure? No, you probably don't; you probably lower the nose slightly to maintain airspeed, so it wouldn't be appropriate to say merely banking causes an accelerated stall.

It's all about the back pressure - the rate of back pressure that causes the accelerated stall, not the bank.
