AIRPLANE GENERAL Flashcards
How does the Flight Deck door respond to pressurization decompression events?
The door features two decompression panels that allow air to vent from the Passenger Cabin into the Flight Deck in the event of a rapid decompression in the Flight Deck.
In the event of a Passenger Cabin decompression, the entire Flight Deck door may open, permitting Flight Deck air to vent into the Passenger Cabin.
Can the Flight Deck door be deadbolted?
Yes, there are three manual locking options:
• UNLOCKED
• LOCKED KEY OPERABLE – not utilized by Alaska Airlines
• LOCKED KEY INOPERABLE
What is the purpose of the FDAS system?
Once closed (with DC bus No. 2 powered), the door is automatically locked with no further crew action required. The FDAS also allows entry to the Flight Deck from the Passenger Cabin in the event of an emergency, such as pilot incapacitation.
When will the overwing emergency exits lock?
The overwing emergency exits lock when:
• three of the four entry/service doors are closed, and
• either engine is running, and
• the aircraft air/ground logic indicates that the aircraft is in the air or both thrust levers are advanced
How is the failure of the overwing emergency exit Flight Lock System indicated?
If a flight lock has failed locked or a fault is detected, the MAINT light and the OVERHEAD System Annunciator and MASTER CAUTION lights illuminate. These indications are inhibited from the first engine start until 30 seconds after landing. When the doors are latched and locked, and the flight lock is operating properly none of these lights will illuminate.
When will the emergency exit lights illuminate?
If electrical power to DC bus No. 1 fails or if AC power has been removed, the emergency exit lights illuminate automatically.
The ON position commands the emergency exit lights to illuminate.
The EMERGENCY EXIT LIGHTS switch on the aft attendant panel may also be used to illuminate the emergency exit lights.
Can the aft attendant panel EMERGENCY EXIT LIGHTS switch override Flight Deck control?
Yes, lifting the guard and pushing the switch ON overrides the Flight Deck control and illuminates the emergency exit lights (even if the Flight Deck EMER EXIT LIGHTS switch is positioned to OFF).
What is the purpose of the MUTE switch on the INTERNET - GROUND control panel?
The MUTED switch, when pressed, deactivates the transmit function of the 2Ku antennas mounted on the upper aft fuselage.
Due to radiation emissions that can be harmful to the human body, personnel should not be within the RF hazard area when the 2Ku satellite antenna is transmitting.
What conditions must be met in order for the AC-powered air compressor in the Potable Water System to operate?
In order for the compressor to operate the following conditions must exist:
• pressure in the system is insufficient
• water service panel door is closed
• CAB/UTIL switch is positioned to ON
How is the crew oxygen mask microphone activated?
Removing the mask:
• selects the mask microphone in the removed mask (the boom microphone is deselected)
How is the PASS OXYGEN system activated?
With the switch in NORMAL, the system is automatically activated at a cabin altitude of 14,000 ft. When required, the PASS OXYGEN switch may be manually positioned to ON to activate the system.
Approximately how long does oxygen flow when the Passenger Oxygen System is activated?
Oxygen flows for approximately 12 minutes
