What is the relationship of lift drag thrust and weight when the airplane is in straight and level flight?

constant airspeed, thrust and drag must remain equal, just as lift and weight must be equal to maintain a constant altitude. If in level flight, the engine power is reduced, the thrust is lessened, and the aircraft slows down. As long as the thrust is less than the drag, the aircraft continues to decelerate.

What is the maximum altitude of an airplane?

Answer: The highest commercial airliner altitude was 60,000 feet by Concorde. The highest military air-breathing engine airplane was the SR-71 — about 90,000 feet. The highest airliner flying today reaches 45,000 feet. The highest business jet flying today reaches 51,000 feet.

How does a plane lift?

How Wings Lift the Plane. Airplane wings are shaped to make air move faster over the top of the wing. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.

What is the relationship of lift drag thrust and weight when the airplane is in straight and level flight quizlet?

What is the relationship of lift, drag, thrust, and weight when the airplane is in straight and level flight? Lift=weight and thrust=drag. One of the main functions of flaps during approach and landing is to? Increase angle if descent without increasing the airspeed.

How does thrust affect an airplane?

Thrust is the force which moves an aircraft through the air. Thrust is used to overcome the drag of an airplane, and to overcome the weight of a rocket. Thrust is a mechanical force, so the propulsion system must be in physical contact with a working fluid to produce thrust.

Do all planes fly at the same altitude?

Q: Do different airlines fly at different altitudes on the same routes? A: No, altitude is not based on the airline. Assigning altitude is first-come, first-served.
