Power-on stall occurs at lower airspeeds in shallower banks.

Power-on stall occurs at lower airspeeds in shallower banks.

• A. Power-on stall occurs at lower airspeeds in steeper banks.
• B. Power-on stall occurs at lower airspeeds in shallower banks.
• C. Power-on stall occurs at higher airspeeds in shallower banks.
• D. Power-on stall occurs at the same airspeeds regardless of bank

Answer: (B)

Power-on stall speed is governed by lift needed to balance weight, which increases in a turn. When you bank, the airplane must generate more lift to stay level, because the load factor rises with bank angle (approximately n = 1/cos(bank)). Stall happens when the wing reaches its critical angle of attack, so the airspeed at which stall occurs increases as the load factor grows. In a steeper bank, you need more lift and therefore a higher airspeed to avoid stalling. In a shallower bank, the required lift is less, so you reach the stall at a lower airspeed. In a power-on stall, where power and pitch are used to produce the stall condition, this same relationship holds: the stall airspeed is lower in shallower banks and higher in steeper banks. That’s why the statement about power-on stalls occurring at lower airspeeds in shallower banks is the best description.
