3 things that cause a stall?

[wmuflyguy]

Came across this question on AviationInterviews.com.

What are the 3 things that cause a stall?

Am i missing something here?

A stall occurs when the ccritical Angle of Attack had been exceeded. I can't think of anythig else that causes a stall.

I guess i'm not sure what they are looking for with the question.

Maybe they are looking at a deeper level... like deenergized boundary layer, adverse pressure gradient, etc.

 

[mattpilot]

perhaps they are looking for simple obvious things...?

Like Low air speed, Abrubt control maneuvers, and ...whateveryacanthinkof

 

[qmaster3]

They are not looking for departure, approach, and trim? Too me those are types, but maybe they need to re-phrase the question.

 

[mattpilot]

Maybe its a trick question. Perhaps they want to find out if you BS your way through the answer by coming up with wierd stuff.

If i were at an interview and i got that question, i'd probably go "I'm sorry, 3?" and then go with the explanation wmuflyguy gave. Then say, "Unless you ment three flight conditions.... then yadaya".

 

[qmaster3]

It's a comair question I believe. You should post something on regionals, and see if any Comair guys bite.

Stalls

A stall occurs when the critical Angle of Attack had been exceeded. I can't think of anythig else that causes a stall.

Nor can I. Exceeding the critical AOA is the only cause for a stall that I learned and taught.

You can stall at any airspeed and at any attitude. Its all about the Angle of Attack

 

[mattpilot]

yes i know that.... but things that can cause you to exceed the AoA are some of the conditions i listed....


Edit: i still think its a trick question

I'm with Vnugget, they must be looking for more detailed aerodynamic explainations -- the flow seperation moving forward as the critical angle of attack is reached, causing the low pressure effect above the wing to go away.. good question to study up on
