"Fuel Quantity BITE" message on EICAS means the FQIS...: Low quantity in any tank. Maintenance advisory for a fault storage on NVM. Major difference of fuel between main tanks.

For the B767-300, from which tank can you jettison fuel from?. Left and right only. All tanks. Center tank.

The "L or R Fuel System Press" message is shown on EICAS if: The main booster pumps of one main tank are off. The respective booster pump on either side is off. All the booster pumps and both crossfeed valves are off.

Pressurization rate is: Adjustable speed for pressurization or depressurization. Same speed on climb or descent. Information used only on ground mode.

When does the Left Fwd Booster pump runs automatically?. When the APU is staring and the aircraft is powered by ground cart. When the APU is starting using Battery power. When the left engine is starting. In order to increase the engine fuel pressure.

What is the purpose of the compensator on the fuel quantity indication system?. To sense the height of the fuel in the tank. To measure the dielectric constant of the fuel. To measure the specific gravity of the fuel and its density.

The check valve for the engine air supply (8th stage) is closed when the...: ..PRSOV is closed. ..HPSOV is open and the engine is running. ..Bleed air temperature exceeds 230 degrees C.

The nose cowl thermal anti-ice (NTAI) system is activated...: ..on ground only during a "thermal anti-ice test" P61 panel. ...when the engines are running and the Engine TAI switch is pushed. ...when the L(R) Engine TAI switch is pushed in and there is no signal from the EEC overheat switch.

How many Air conditions Packs are in the 767?. There are three packs, one for the Flight deck, other for the Fwd zone, the thirth for Economy zone. There are two Packs. There is one main Pack.

Is the Pack Temp. Controller able to control the Low Limit Valve?. Yes, if the pack outlet temperature drops below 40F (Antiice protection). No, only the Standby Controller is able to use the LLV during STBY-N mode. Yes, if a Compressor Overheat 450F is detected.

What is the purpose of the Inert Gas System?. To remove nitrogen molecules from the main fuel tanks and discharge them overboard. To remove the nitrogen from the center auxiliary fuel tank by means of oxygen injection. To remove the oxygen from the center auxiliary fuel tank by means of nitrogen injection.

Pack system. Auto Mode. if 425F are reached: Pack Over Heat occur. HI Flow throttling is activated. LLCV open.

What are the function of the PRSOV?. To control the airflow from the 8th stage. Anti ice and reverse operation. Shut off, pressure regulation, temperature control and reverse protection.
