• Class B, C, and D

• Class A, B, C, D, and E

Hyperventilation can lead to

• A lack of oxygen

• Profuse sweating

• Light-headedness

(Refer to Figure 2, Load Factor Chart) If an unmanned airplane weighs 33 pounds, what approximate weight would the airplane structure be required to support during a 30° banked turn while maintaining altitude?

• 34 pounds

• 47 pounds

• 38 pounds

When are the four forces that act on an airplane in equilibrium?

• During unaccelerated flight.

• When the aircraft is accelerating.

• When the aircraft is at rest on the ground.

What is the relationship of lift, drag, thrust, and weight when the airplane is in straight-and-level flight?

• Lift equals weight and thrust equals drag.

• Lift, drag, and weight equal thrust.

• Lift and weight equal thrust and drag.

Which of the following will increase load on the wings of a fixed-wing UAV?

• Decreasing thrust

• Anytime the aircraft is subjected to maneuvers other than straight-and-level flight

• Increasing thrust

You see a manned aircraft in the distance while flying your drone at night. On the left, you're seeing a green light. On the right, you're seeing a red light. Which direction is the aircraft headed?

• it’s heading towards you

• it depends how bright the lights are

• it’s heading away from you

An aircraft announces, "left downwind for runway two six". This means that the aircraft is on a heading of

• 80 degrees.

• 160 degrees.

• 340 degrees.

Answer explanation

Runway 26 is positioned toward 260 degrees, meaning that when airplanes are taking off or landing, they're doing so at a heading of 260 degrees. In a normal left-hand traffic pattern...if a plane is midfield left downwind RWY 26, it means that the plane is flying parallel to the runway, in the opposite direction (downwind) of the runway, at a heading 180-degrees opposite of the runway. So in this case, the plane is flying 180 degrees opposite of 260 degrees, which is 80 degrees!
