Question

raspet flight research laboratory, housed at mississippi state university, supports the university’s goals of teaching, research, and service. one of the aircraft used by the lab is the owl, an ultralight sailplane designed to be an optionally piloted aircraft (opa). the owl is a single-place, all-composite sailplane. a single person can guide this plane while flying or remotely. soaring flight, maintaining or gaining altitude rather than slowly gliding downward, is the reason most glider pilots take to the sky rather than flying remotely. soaring flight relies on the pilot finding thermals in the atmosphere that carry the sailplane up. these thermals help with what force while soaring in the owl? a drag b lift c thrust

Explanation:

The problem is about the forces acting on an aircraft (the Owl sailplane) during soaring flight. Thermals help carry the sailplane up, which relates to the force of lift. Lift is the upward force that opposes weight and allows an aircraft to stay aloft. Thrust is forward force, drag is backward/resistive, and weight is downward. Thermals provide the upward movement needed for lift to keep the sailplane soaring.

Answer:

B. lift
