Why is it important for there to be no ice on the wing of an airplane? Select all that apply.
Ice makes the wings slippery.
Ice makes the airplane heavier.

Fabrics used in the construction of modern aircraft have improved when compared to vintage aircraft because:
they are stronger, more durable, and resistant to weathering.
they are heavier and less flexible than vintage fabrics.
they are made entirely from natural fibers like cotton.
they require more frequent maintenance than vintage fabrics.
The danger of an airliner becoming depressurized at a very high altitude is that:
Passengers can lose consciousness due to lack of oxygen.
The airplane will immediately explode.
The engines will stop working instantly.
The airplane will automatically land safely.
Weight is an important consideration when designing a drone because:
it affects the drone's ability to fly efficiently.
it determines the color of the drone.
it controls the drone's camera quality.
it decides the brand of the drone.
Anti-torque pedals are used to change the direction a helicopter points while it is in flight by:
controlling the pitch of the tail rotor blades to counteract torque and yaw the helicopter
increasing the speed of the main rotor to turn the helicopter
adjusting the landing gear to shift the helicopter's direction
moving the cyclic stick to tilt the helicopter sideways
Identify which component of a rotorcraft creates lift.
Main rotor blades
Tail rotor
Landing skids
Cockpit
