100-200 part 2

In the majority of helicopters, the thrust generated by the gas generator is absorbed by the.(Level 1)

• L.P turbine.
• Free power turbine.
• H.P turbine.

An A.P.U start cycle is completed at.(Level 1)

• 100% RPM.
• 75% RPM.
• 95% RPM.

An A.P.U power lever is located.(Level 1)

• behind the throttles.
• at the Flight Engineer Station.
• An A.P.U is fully automatic and does not require a power lever.

An A.P.U consists of.(Level 1)

• a power compressor and load compressor.
• a power compressor and directly connected turbine.
• a load compressor and free turbine.

Frequently, an aircraft's auxiliary power unit (A.P.U) generator.(Level 1)

• is identical to the engine-driven generators.
• has a higher load capacity than the engine-driven generators.
• supplements the aircraft's engine-driven generators during peak loads.

Fuel scheduling during A.P.U start and under varying pneumatic bleed and electrical loads is maintained.(Level 1)

• automatically by the A.P.U fuel control system.
• manually through power control lever position.
• Jeppesen A&P Technician Propulsion Textbook 3-37.

An A.P.U is usually rotated during start by.(Level 1)

• a pneumatic starter.
• a turbine impingement system.
• an electric starter.

For an A.P.U to run 'unmanned' it must be equipped with.(Level 1)

• an automatic fire extinguishing system.
• both an audible fire warning and an automatic fire extinguishing system.
• an audible fire warning.

An aircraft has a heavy landing and on inspection of the engine mounting bolts the bolts torque loading has reduced, you should.(Level 1)

• add washers to take up any gap or slackness and re-torque to correct value.
• remove bolt and carry out inspection as the bolt may have increased in length due to heavy landing.
• re-torque bolt up to correct torque value.

Forward engine mounts take which loads?.(Level 1)

• Thrust, vertical and shear loads.
• Centrifugal, thrust and axial.
• Thrust, vertical and impact.
