## Q: How does the thrust affect the weight of a plane?

Categories: Forces of Flight

## Q: You claim that to maintain level flight, "lift must equal weight and thrust must equal drag." If thrust equaled drag, wouldn't the aircraft be stationary? Doesn't thrust always have to exceed drag in order for the aircraft to move forward?

## Q: I assume that a jet engine reaches maximum thrust at take-off and lift to cruising elevation and reduced thrust while landing. At what percent of maximum thrust at ideal flight conditions does the engine deliver?

## Q: Since Newton`s first law of motion can be derived from the second law of motion, what is the relevance of the first law of motion?

Categories: Forces of Flight

## Q: If lift=weight and thrust=drag in a steady level flight, what provides the acceleration at that instant?

## Q: How does weight, thrust, lift, and drag help the airplane fly?
