What are the forces

Question

A helicopter accelerting downward. Diagram all the forces acting on the helicopter 

Answer 1

Hey Mike.

Any aircraft always has 4 forces acting on it.

-upward is lift

-downward is weight

-forward is thrust

-rearward(aft) is drag

Pilots control aircraft by managing these four forces. In your example the pilot would be allowing thrust and weight to increase causing the helicopter to accelerate and descend.
