CHAPTER 30 Flashcards
Wing anti-ice supply to both wings is controlled by a single pushbutton switch on the overhead ANTI ICE panel. Which leading edge slats are supplied?
Hot air from the pneumatic system is provided for the anti-icing of the three outboard leading edge slats (3, 4 and 5) of each wing.
In order to provide reliable information for the air data systems how are is the heating of aircraft probes controlled?
The air data probes are heated AUTOMATICALLY when at least one engine is running.
Which flight deck windows are heated and how is this controlled?
The front windshields and side windows are heated AUTOMATICALLY when at least one engine is running. The PROBE/WINDOW HEAT pushbutton switch (normally in the AUTO position) may be used to select the window heating ON with the engines shut down.
How is engine anti-ice controlled?
Engine anti-ice is manually selected by the crew and is available in flight or on the ground with the engine running.
How is engine anti-ice supplied?
Each engine air intake is protected from ice by an independent air bleed supply from the high-pressure compressor of that engine.
If engine anti-ice is selected when the aircraft is on the ground how is that displayed on the flight deck?
If at least one of the two engine air intake anti-ice protection systems is selected ON, a message appears in green on the upper ECAM MEMO display.
If power is lost to the PHC or Engine Interface Unit (EIU) what is the effect on the flight data probes?
Pulling the PHC or Engine Interface Unit (EIU) power supply C/Bs causes unwanted heating of the probes and static ports. The are fail safe to on.
If power is lost to the PHC with the aircraft on the ground what default setting will the standby probe heat be set to?
The standby probe heat system has no Total Air Temperature (TAT) heating.
In case of failure, the aircraft may be dispatched per Minimum
Equipment List with the RH WING anti-ice valve deactivated in the OPEN position or either valve in the CLOSED position. What special crew actions must the crew observe if deactivated OPEN?
If the valve is deactivated OPEN, the associated engine bleed switch must be selected OFF until after takeoff.
In case of a failure of a drain mast heater, where will the fault be displayed?
The fault will be displayed on the Flight Attendant Panel (FAP) of the Cabin Intercommunication Data System (CIDS).
In case of a failure of a drain mast heater, can the aircraft be dispatched with use of Minimum Equipment List (MEL)?
The aircraft can be dispatched but the water supply to the Lavatory (LAV) and galley which use the failed drain mast must be shut off. As a result, the LAV will not be usable and must be secured closed and locked.
