What does the "LRU STATUS" indicator on the VHF transceiver show?. Displays a fault in the antenna system. Indicates a failure of the transceiver. Identifies a problem with the ARINC 429 input.

What happens during a successful self-test of the voice recorder system?. Meter moves steadily to the greenband and a 620Hz tone is heard. Meter stays in the red zone and a 400Hz tone is produced. All indicators lights flash while the horn sounds continuously.

What is the main function of the Audio Management Unit (AMU)?. Provides routing and processing of audio from the audio control panels. Controls illumination of communication selector panels. Supplies electrical power for the audio amplifiers.

What is the main function of the ACARS Management Unit (MU)?. Regulates the cabin pressurization and environmental systems. Controls the transmission of uplink and downlink messages through the radio transceiver. Stores and prints maintenance reports for ground engineers.

What is the purpose of the Passenger Address (PA) system: To allow the passengers to make phone calls from the aircraft to the ground. To allow the flight crew to transmit speech communications to the Air Traffic Control. To allow the flight crew or flight attendants to transmit announcements to the passengers.

What is the function of the P~ LEVEL control screw located on the front of the Audio Accessory Unit?. It adjusts internal sense control during power-up tests. It routes the PA output signals through the interphone amplifiers. It sets the proper sound level from the passenger cabin speakers during speaker tests.

When the SERV INTPH switch on the P61 panel is moved to ON, what occurs in the Service lnterphone system?. Power isolation prevents the jacks from communicating with the audio panels. The PA amplifier links the cabin crew headsets to the cockpit units. Connection is made between the flight interphone system and the service jacks.

Which chime tone is produced when the "FASTEN SEAT BELT/NO SMOKING" signs are turned on?. Single high chime is generated. Alternating high and low chime. A low-chime is generated.

What PA (Passenger Address) system announcements have priority 3?. Flight attendants announcements. Pre-recorded audio announcements. Boarding music.

What is the primary role of the transformer in the passenger address speaker circuit?. Match the speaker voice coil impedance with the amplifier output. Regulate the power supply to the passenger service units. Isolate the speaker lines from the cabin interphone network.

What causes a 3 db increase in PA (Passenger Address) amplifier volume?. First engine start. Oxygen system deploying. Forward entry door closing.

Which system is used to remove raindrops anct water from the windshields?. The Windshield Wiper System. A hydrophobic coating on the windshield. None; the airflow removes water deposits.

What material are the sidewall panels made of?. Aluminum alloy with vinyl coating. Graphite composite with Tedlar lamination. Fiberglass sheet with epoxy layer.

How are the lavatory modules installed?. Mounted on floor or seat tracks and attached by overhead tie rods. Hung from ceiling beams using bracket supports. Bolted directly to fuselage frames and side panels.

What components are included in the restraint system flight crew seats?. Lap belt, intertia reel, and headrest. Shoulder harness, lap belt, and crotch strap. Shoulder harness, thigh pad, and lumbar strap.

What must be done before sliding the flight crew seat off the tracks?. Pull the seat aft to engage the forward stops. Use the manual override to disengage the actuator. Turn the bogies to lock the rollers in place.

How are the passenger indirect ceiling lights powered and controlled?. 28vDC from main DC bus, regulated to 200vAC by inverter and cabin panel. 115vAC from ground service bus, transformed to 350vAC and switched by cabin panel. 115vAC from transfer bus, boosted to 400vAC and controlled by cabin panel.

How are the incandescent threshold entry lights operated?. Energized by door proximity switches when armed. Powered continuously from the 280vAC service bus. Controlled only by the L ENTRY CEILING ON/OFF switch.

How are the passenger night lights powered and distributed?. 28vDC from left bus for all lights, no transformer used. 28vDC from right bus for forward lights, 115vAC stepped down for mid and aft. 115vAC from transfer bus directly to all night light relays.

What happens to the integral and ligthplates Ughts when both 115vAC buses fail?. They come on dim through the standby bus relays. They turn off until AC power is restored. They go bright through the transfer bus power.

How are the glareshield and aisle stand floodlights powered?. Glareshield 115vAC left bus, aisle stand 28vDC standby bus. Both glareshield and aisle stand use 28vDC left bus. Glareshield 28vDC standby bus, aisle stand 115vAC left bus.

What is the system that controls Autothrottle function: The Autopilot Flight Director System (AFDS). The Thrust Management System (TMS). The Flight Management Computer System (FMCS).
