To maintain level flight during a bank, which two factors must increase?

In level flight during a bank, the aircraft experiences a change in the load factor due to the angle of bank. As the angle of bank increases, the load factor also increases. This is because a banked turn generates a vertical component of lift that must not only support the weight of the aircraft but also provide the horizontal component necessary for the turn. Thus, to maintain level flight and counteract the increased load factor, thrust must also increase.

In this situation, maintaining altitude requires that the increase in lift needed due to the load factor be matched by a corresponding increase in thrust. As the bank angle increases, the aircraft needs to produce more lift to counteract the increased demands, which is why thrust must increase as well—to compensate for not only maintaining level flight but also ensuring that the aircraft can overcome any additional aerodynamic drag created by the bank.

The other factors, while critical during flight, do not pertain directly to the scenario of banking and maintaining level flight. For example, altitude remains constant in level flight, and while speed can influence performance factors like drag, it does not directly relate to the necessary adjustments in load factor and thrust during a banked maneuver. Thus, selecting the pair of factors related specifically to maintaining level flight during a bank highlights
