Can you change the four forces in flight in any way?

Answer 1

Of course. That's exactly how you steer an airplane.

-- Running the engines faster increases the thrust, which increases the airspeed.

-- Increasing the airspeed or the angle of attack increases the lift, which makes the plane climb.

-- Increasing the drag causes the airspeed to decrease, which causes the lift to decrease.

-- Decreasing the airspeed or the angle of attack decreases the lift, which can be used to lose altitude.

-- Using control surfaces to increase the lift of one wing while decreasing the lift of the other wing

causes the airplane to bank toward the wing with less lift.

-- Increasing the angle of attack during a bank causes the plane to be 'lifted' around a turn.

-- Extending flaps increases both lift and drag. If thrust is maintained at the same time, the airplane

loses airspeed but maintains altitude.

Anything you want the airplane to do is accomplished by manipulating the four forces in flight.

Answer 2

The four fundamental forces (lift, weight, thrust, and drag) in flight cannot be changed, as they are essential components governing an aircraft's motion. However, pilots can adjust the thrust and control surfaces to manage these forces effectively and control the aircraft during flight.
