Well, I don't know the examiner who would ask such a thing.
STALL means STALL = Loss of speed and control.
Holding 75 kts is not going to get you anywhere "near" stall in a C-172 unless you are willing to pull the wings off the thing. => High "G" load.
And then, with Flaps. . Come on . . . Max "G" load with flaps is 2 G.
Flaps + holding 75 kts? => You can fly the tanks dry without ever getting "ANYWHERE" close to stalling.
You are AT LEAST 15 kts ABOVE a possible stall.
Add some power to that and you are 20 kts ABOVE stalling.
We used to fly a C-172 right into the stall, add power, add more power till at FULL power and cruise along at 30 kts indicated.
With only 2 on board and light on fuel, we could get to 27 kts IAS. Yeah, yeah, that poor horn blaring like a stricken goat. LOL.
It' called flying on the back side of the stall speed. Transfer weight from the wing to the powerplant.
Less weight for the wing to carry and the stall speed drops off to ridiculous values.
BALL centered at ALL times. That's the only "must do".
