Question !
How can we determine the stalling speed for the aircraft
(regardless of checklist or manual,I want express the calculation by formula)

we can determine it by use this formula :

VSA = VS √N

* where :

- VSA is accelerated stall speed
- VS is unaccelerated stall speed
- N is the Load Factor ( In G's)
forexample
an aircraft with an stall speed of 55Kts is flown in a 60 degrees bank, as mentioned earlier, a 60 degrees bank results in a 2 G's load factor

VSA = VS √N
VSA = 55 √2 = 55 X 1.41 = 77.55

the result shows that an aircraft with unaccelerated stall speed of 55kts will actually stall at 77kst at a 60 degrees bank.

that's it .

hope to be clear & understandable for all
