Initial Maneuvers Training (IMT) 1 Practice Exam

Bank angle in a turning maneuver is chosen to achieve the intended turn rate while keeping the turn smooth and coordinated. The bigger the bank, the faster the turn and the tighter the radius, so you set the bank to match the desired rate of turn. Airspeed does affect how much bank is needed for a given rate (faster speed generally requires more bank), but the primary factor you’re responding to is how fast you want to turn and how you’ll keep the turn stable. Altitude and outside air temperature influence aircraft performance (power, stall speed, climb), not the immediate intention of the turn, so they’re not the main factor in selecting bank. For practice turns, you focus on the target rate of turn (and maintain a stable, coordinated input), which is why the factor described is the best choice.
