What is the stall speed of a training airplane with flaps up in a 60-degree bank?

The stall speed of an airplane increases as the angle of bank increases, due to the increased load factor on the aircraft. In a 60-degree bank, the load factor is approximately 2, meaning that the aircraft experiences twice the normal forces acting on it.

To calculate stall speed in a banked turn, you can use the formula:

Stall Speed in a Turn = Stall Speed in Level Flight × √(Load Factor)

For most training aircraft, the stall speed in level flight with flaps up is typically around 60 to 70 knots (roughly 69 to 81 mph depending on the aircraft). Given that the increase in stall speed due to a 60-degree bank makes it approximately 1.414 times higher than the stall speed in level flight (since √2 is approximately 1.414), this adjustment leads us to a stall speed around the higher end of the typical range when in a banked turn.

In this case, if the stall speed in level flight is roughly 60 to 70 mph, then applying the load factor would lead to a stall speed of around 78 mph, supporting the choice for a training airplane with flaps up at a 60-degree bank being 78 MPH. This aligns with
