Q:

How does a helicopter remain stationary in the air?

A:

A helicopter remains stationary by balancing the external forces. There are no horizontal forces, as the helicopter is not moving left or right, so there is no drag or horizontal thrust. The blades generate a vertical lift, and when this is exactly balanced with the force of gravity, the helicopter remains stationary. This is due to Newton's Second Law
