A.R_MAJOR EXAM.3

If a single-rotor helicopter is in forward horizontal f light, the angle of attack of the advancing blade is

• more than the retreating blade.
• equal to the retreating blade.
• less than the retreating blade.

What is the purpose of the free-wheeling unit in a helicopter drive system?

• It disconnects the rotor whenever the engine stops or slows below the equivalent of rotor RPM.
• It connects the rotor whenever the engine stops or slows below the equivalent of rotor RPM.
• It disconnects the rotor whenever the engine go or slows below the equivalent of rotor RPM.

If a pilot reports that an airplane flies left wing heavy, this condition may be corrected by

• increasing the angle of incidence of the left wing, or decreasing the angle of incidence of the right wing, or both.
• increasing the angle of incidence of the right wing, or decreasing the angle of incidence of the right wing, or both.
• increasing the angle of incidence of the left wing, or increasing the angle of incidence of the right wing, or both.

The angle of incidence is that acute angle formed by

• a line parallel to the wing chord and a line perpendicular to the longitudinal axis of the aircraft.
• a line parallel to the wing chord and a line parallel to the longitudinal axis of the aircraft.
• a line parallel to the wing chord and a line parallel to the lateral axis of the aircraft.

If the right wing of a monoplane is improperly rigged to a greater angle of incidence than designated in the manufacturer’s specifications, it will cause the

• airplane to be off balance both laterally and directionally.
• airplane to be on balance both laterally and directionally.
• airplane to be off balance or laterally and directionally.

The vast majority of aircraft control cables are terminated with swaged terminals, that must be

• checked with a go-no-go gauge after, to show compliance with the manufacturer’s requirements after the swaging operation.
• checked with a go-no-go gauge before and after, to show compliance with the manufacturer’s requirements before the swaging operation.
• checked with a go-no-go gauge before and after, to show compliance with the manufacturer’s requirements after the swaging operation.

When inspecting a control cable turnbuckle for proper installation, determine that

• the safety wire ends are wrapped a maximum of four turns around the terminal end shanks.
• the safety wire ends are wrapped a minimum of five turns around the terminal end shanks.
• the safety wire ends are wrapped a minimum of four turns around the terminal end shanks.

Where does the breakage of control cable wires occur most frequently?

• Breakage usually occurs where cables pass over pulleys and through fairleads.
• Breakage usually occurs where cables pass through pulleys and over fairleads.
• Breakage usually occurs where cables pass over pulleys and over fairleads.

Which statement concerning the 100-hour inspection of an airplane equipped with a push-pull tube-type control system is true?

• The threaded rod ends should be checked for the amount of thread engagement by means of the inspection patch provided.
• The threaded rod ends should not be checked for the amount of thread engagement by means of the inspection hole provided.
• The threaded rod ends should be checked for the amount of thread engagement by means of the inspection hole provided.

During inspection of the flight control system of an airplane equipped with differential-type aileron control, side-to-side movement of the control stick will cause

• each aileron to have a greater up travel (from the streamlined position) than down travel.
• each aileron to have a greater up travel (from the streamlined position) than up travel.
• each aileron to have a greater down travel (from the streamlined position) than down travel.
