SIFT Aircraft Components and Controls 2

Question 1

What is the primary function of the horizontal stabilizer on a helicopter?

Accepted Answer

Controls pitch attitude at cruise speeds

Answer

The horizontal stabilizer on a helicopter helps control pitch attitude at higher cruise speeds, reducing pilot workload.

Question 2

Which component of a fixed-wing aircraft is responsible for roll control?

Accepted Answer

Ailerons

Answer

Ailerons are the primary roll control surfaces located on the trailing edge of each wing, working differentially to bank the aircraft.

Question 3

In a conventional helicopter, pushing the cyclic stick forward causes the aircraft to:

Accepted Answer

Pitch nose-down and move forward

Answer

Pushing the cyclic forward tilts the rotor disk forward, which pitches the nose down and propels the helicopter in the forward direction.

Question 4

What does the 'collective' control on a helicopter primarily regulate?

Accepted Answer

Overall pitch of all rotor blades simultaneously

Answer

The collective changes the pitch angle of all main rotor blades simultaneously, controlling the total lift produced and vertical movement.

Question 5

What is the purpose of trim tabs on a fixed-wing aircraft?

Accepted Answer

Reduce required control force to maintain a desired attitude

Answer

Trim tabs reduce the control pressures a pilot must exert by creating small aerodynamic forces that hold the primary control surface in a desired position.
