To maintain straight and level flight when thrust changes, what is required?

• A. Elevator trim
• B. Coordinate AOA
• C. Rudder input
• D. Flaps setting

Answer: (B)

Maintaining straight and level flight as thrust changes relies on adjusting the angle of attack to keep the lift equal to the weight at the current airspeed. When power changes, the aircraft tends to speed up or slow down, which would change the lift produced for a given configuration. By coordinating the angle of attack (through pitch adjustments), you modify the lift to match the weight again, keeping the flight path steady and the aircraft from climbing or descending. If thrust increases, you would adjust attitude to lower the angle of attack enough to prevent excess lift; if thrust decreases, you would raise the angle of attack to increase lift. This is the key way to stay straight and level without relying on fixed trim alone or other controls like rudder or flaps.
