Forces in Flight

Flight Review

Newton's has 3 laws

• 1st Law - object will stay at rest until an unbalanced force moves it; an object will stay in motion until a force stops it.

• 2nd Law - force is equal to mass x its acceleration

• 3rd Law - for every action there is an opposite and equal reaction

Which of Newton's laws does the picture depict?

Which two arrows show the equal and opposite forces that demonstrate Newton’s Third Law that causes liftoff? Select two letters.

Each of the following causes a movement of the plane.

• Yaw - moves the plane vertically with the stabilizers

• Roll - moves the plane longitudinal (left or right) using the wings

• Pitch - moves the plane horizontally with the horizontal stabilizers

Multiple Choice

Which action creates a difference in the lift on each wing, causing the plane to roll?

• Moving the rudder left or right.

• Raising or lowering the elevators.

• Decreasing engine thrust.

• Raising one aileron (wings) and lowering the other aileron (wings)

Open Ended

When would be the best time for the pilot to lower the ELEVATORS on the back of the horizontal stabilizers?

Forces of Flight

• Lift

• Drag

• Weight/Gravity

• Thrust

Multiple Choice

What happens when there is less thrust and more drag on a plane?

• It will slow down.

• It will accelerate.

• It rises.

• It will descend.

Open Ended

A military cargo plane is loaded with the maximum weight allowable for the flight. The cargo is heavier than what the pilot usually carries. What will the pilot need to do to be able to take off without any issues?

Multiple Choice

The parachutes in this diagram are slowing down the capsule using what force?

• Thrust

• Lift

• Drag
