Where can you get information of water level?. From central maintenance computing function (CMCF) only. From cabin attendant panel (CAP) only. From cabin attendant panel (CAP) and potable water service panel.

In relation to air conditioned ground connection, the 787-9 has: Two connections, one on each pack. a single connection. in 787-9 its not necessary gnd connections.

In reference to the second observer seat: It is attached to the aft bulkhead and has no adjustments. It is attached to the aft bulkhead and has an electrical adjustment only. It is attached to the aft bulkhead and has electrical and manual adjustments.

Which component processes data from cargo doors proximity sensors?. Proximity switch electronic unit (PSEU). Proximity sensor data concentrator (PSDC). Remote data concentrator (RDC).

Which is the main function of trim air pressure regulator valve?. It controls the temperature to different cabin zones. It controls the pressure of the trim air to the trim valves. It controls a possible overcurrent of CAC.

How can you activate the FWD cargo heat operation?. From cabin attendant panel (CAP). When air condition is detected, the CCS controls automatically cargo compartment temperature. From associated P5 overhead panel Switch.

What will happen if the Mode Selector lever is set in position Auto (Armed), and the door is opened from outside?. It will not be possible to open the door from outside with the mode selector lever in Auto (Armed). If The EPA system operated, the door will open in emergency mode and the slide will deploy. The mode selector lever will go to Manual (desarm), and the door will open normally.

How many smoke detectors are there in FWD EE cooling system?. Two smoke detectors, both are located in the exhaust airflow near the FWD outflow valve. Two smoke detectors, one in the supply airflow and one in the exhaust airflow. One smoke detector in the supply air flow.

How many sections does the air cycle machine have?. Three sections; compressor, T1 and T2 turbines. Three sections; fan, compressor and turbine. Two sections; turbine and compressor.

the passanger oxygen system, when the masks are deployed: The oxygen starts to flow inmediately. The oxygen starts to flow when any mask is pull by the passenger. The oxygen starts to flow when the passenger puts on the mask and breath.

In B787 the gray water goes: To the UV module and then to the water tank. To the waste tank. To the FWD or AFT drain mast and then overboard.

To supply water through the water faucet, the system uses: Aircraft pneumatic pressure. Two electrical water pumps. Differential pressure.

In the air conditioning system, the Heat Exchanger for cooling the air, uses: Air taken from the engines (Fan Air). Air from the electrical compressors. Ram air from the ambient air.

The flight compartment windows have: An electrically conductive layer that prevents fog and ice. A pneumatically duct to prevent ice in FWD windows only. An electrically conductive layer that prevents fog only.

If the positive pressure relief valves (PPRV) were activated, then you need: To reset the valves manually. To replace the affected valves. To perform a CMCF test to reset the valves.
