In steady, level flight, how must lift relate to the weight of the UA?

In steady, level flight, for a UAV (unmanned aerial vehicle) to maintain its altitude, the lift generated by the wings must be equal to the weight of the vehicle. This balance ensures that the upward force (lift) counteracts the downward force (weight), allowing the UAV to fly straight and level without climbing or descending.

If lift were greater than the weight, the UAV would ascend. Conversely, if lift were less than the weight, the UAV would descend. This principle is fundamental to the mechanics of flight and is essential for understanding how to control a UAV effectively. Therefore, the correct relationship between lift and weight in steady, level flight is that they must be equal.
