During level, unaccelerated flight, which statement is true about lift and weight?

Explanation:
In level, unaccelerated flight the vertical forces must balance. Lift acts upward from the wings, while weight pulls downward due to gravity. To have zero vertical acceleration, the net vertical force must be zero, so the lift produced by the wings equals the aircraft’s weight. This balance keeps the airplane at a constant altitude. If lift were greater, the aircraft would climb; if lift were less, it would descend. In steady level flight, pilots trim and adjust speed to maintain lift equal to weight.
