Review phase 4

How is the AU protected during startup to avoid high temperature?

• by a sequence computer who controls the fuel

• by a computer that controls the air mass

• due to a reduction in spark intensity

The out flow valves will open due to

• Hi air pressure through automatic control

• Low air pressure through automatic control

• By a torque motor that drives the mechanism

Of the following, which faults will automatically shut down the APU?

• HI oil temperature, low oil press, over speed. low fuel flow

• HI oil temperature, low oil press, over speed. low speed, apu fire

• HI oil temperature, low oil press, low speed. ambient tempersture

The main difference between engine and APU extinguisher systems is

• The contents of the fire extinguisher bottle

• the test, because the apu FWCU test requires protection to prevent self-discharge

• The wiring is data buses

HOW THE SPRAG CLUTCH OF THE APU IS LUBRICATED?

• By oil into its own sump

• By the same APU oli circuit

• by oil that is served through the filling plug

What precautions must be taken to perform the Engine anti ice test?

• All persons around the engine must be alert due hi temperature

• 115AC must be available to do the test

• An engeneer must turn the propeller until the test is over

What is required for the cockpit recirculation fan to start working?

• the P/B must be on and FD airconditioning valve must be open

• The P/B must be ON and one pack must be OFF

• The P/B must be on and the engines must be running

Which of the following countries is not from Africa?

• Mali, Costa de Marfil Tanzania, Santo Tome y Principe

• Guinea, Angola ,Sierra Leona and Turkey, Gabon

• Sudan , Mauricio , Eritrea, Suazilandia, Niger

What is the difference between heavy and light in the DE-icing system?

• the rest time at the end of the sequence

• the amount of air pressure if the ice is soft or hard

• the sequence time to keep the boots inflated*/deflated

If you close a little bit the out flow valves

• Differential pressure increase , the internal pressure decrease, the cabin altitude decrease

• Differential pressure increase , the internal pressure increases,the cabin altitude decrease

• Differential pressure decreases , the internal pressure increase, the cabin altitude increases
