The four forces of flight are also referred to as...

• friction, power, gravity, and lift

• power, push, pull, and lift

• friction, power, pull, and gravity

While balancing the forces of flight, when thrust equals drag...

• Gravity = Lift

• Drag = Weight

• Lift = Pull

Bernoulli's principle is related to which of these statements?

• For every action, there exists an equal and opposite reaction

• The upward force generated over the lower surface of the wing deflects air downward

• Air travelling faster over the curved upper surface of an airpoil causes lower pressure on the top surface

Which of these forces of flight has a vertical axis downward through the center of gravity?

• Thrust

• Lift

• Weight

How must a sUAS fly in order to balance the forces of flight?

• Straight-level-unaccelerated flight

• Straight ahead flight

• Vertically and Horizontally balanced flight

Improperly loaded or overloaded fixed-wing UAS will NOT result in...

• needing a longer run for takeoff

• having a pitched up nose and stalling

• being controllable at full power

When an airflow/wing stalls, the angle of attack will...

• increase the center of gravity

• remain the same regardless of gross weight

• change when there is a slight increase in the gross weight

Prior to every flight operation, the remote pilot should always ensure that...

• the flight operation is approved

• the load of the sUAS has been checked by the ATC

• any load put on the sUAS is fully secured
