Stalling

[mstram]

"B) Can we find an angle of attack at which the airplane will not stall below stalling speed? (If I am correct, the answer is "no". Because if such angle existed, it would exceed 15 degree, right?)"


The answer is yes - if you allow the aircraft to descend. You can fly below the stall speed (as defined above) provided you reduce the angle of attack = reduced lift = descending

Ok ...

But can you actually get a plane to fly below descending 1g stall speed while making it descend?

C) What is load factor? and how can it affect the indicated stalling speed?
