If there is any conflicting information, your FCOM shall be the overriding reference.

Q1. What is the definition of icing conditions?

A1.  Icing Conditions are said to exist when the OAT on the ground or TAT in flight is 10°C (50°F) or below and visible moisture is present (such as clouds, fog with a visibility of 1500m (1sm.) or less, rain, snow, sleet or ice crystals); or standing water, slush, ice or snow is present on the ramps, taxiways or runways.

Q2. It is the first flight of the day and you are doing your cockpit preparation. Due to the cold weather operation, the PROBE/WINDOW HEAT p/b is selected ON. Will the windshield heat be operating? At what level?

A2.  Yes, the windshield heat would be operating. Windshield heating operates at low power on the ground.

Q3. After engine start the F/O selects the EAI pushbutton ON. The FAULT light illuminates, what does this FAULT light indicate?

A3.  The Amber FAULT  light comes on, and caution message appears on ECAM, if the position of the anti-ice valve disagrees with the ENG 1 (2) pushbutton selection.

Q4. After engine start, you turn on EAI? What should you do in the event of an EAI Fault?

A4.  After Engine start, EAI is switched on in case Icing Conditions prevail. If after switching on EAI, FAULT light comes on ( Valve does not open ), increase the N2 of the engine by 5%. When the valves are open, retard thrust levers to idle.

Q5. What happens when EAI is ON?

A5.  When EAI is selected ON, the ECAM MEMO displays “ENG A. ICE”.

      –>  Engine anti-icing valve opens if bleed air is available from the engine.

      –>  Continuous ignition is selected when the valve is opened and the ENG ANTI ICE pb-sw is selected   ON. This makes the IGNITION memo appear on the ECAM.

Q6. What affect does Engine Anti-Ice have on engine performance?

A6.  The Engine Performance is reduced with the usage of Bleed Air for the purpose of supplying hot air for Engine Anti-Ice function.

Q7. What happens to engine RPM when either engine anti-ice valve is open?

A7.  The Engine RPM is increased when either engine anti-ice valve is open.

Q8. When should engine anti-ice be used?

A8.  Engine anti-ice should be used when icing conditions are encountered.

Q9. With EAI selected ON, what types of memos will be appearing?

A9.  With EAI selected ON, the following MEMOS would appear :-

  –>  ENG A.ICE

  –>  IGNITION.

Q10. While operating in icing conditions electrical power for the ice protection systems is lost, are EAI and WAI still available?

A10.  EAI would be available and WAI would not be available.

Q11. After landing with icing conditions present, when should the EAI system be selected OFF?

A11.  EAI should be selected OFF after Parking.

Q12. On approach, when should WING anti-ice be selected OFF?

A12.  Wing anti-ice operation:

–>  Normally, WING ANTI ICE should be selected OFF at the FAF

–>  If in severe icing conditions, WING ANTI ICE may be left ON for landing

Q13. What part of each wing is anti-iced with pneumatic bleed air?

A13.  Hot air from the pneumatic system heats the three outboard slats (3-4-5) of each wing.

Q14. What happens when Wing Anti-Ice is on and a bleed leak is detected?

A14.  If the system detects a leak during normal operation, the affected side’s wing anti-ice valve automatically closes

Q15. Can APU be used for wing anti-ice?

A15.  Yes.

Q16. Can wing anti-ice be used in a single engine situation?

A16.  Yes.

Q17. After takeoff, when should WING ANTI-ICE be selected ON, if needed?

A17. After Take-Off,  Select WING ANTI ICE ON after thrust reduction altitude.

Q18. What happens if the wing anti-ice p/b is switched ON, on the ground?

A18.  When the WAI p/b is switched ‘ON’ on the ground, the WAI test sequence is initiated and the valves open only for 30 seconds.

Q19. Which slats are anti-iced?

A19.  The three outboard slats (3-4-5) of each wing are anti-iced.

Q20. When will probe heat automatically come on?

A20.  The probes are heated automatically when at least one engine is running, or when the aircraft is in flight.

Q21. What happens to the heat at the drain masts when the aircraft is on the ground?

A21.  The drain masts are heated any time the electrical system is powered.

Q22. Is electrical heat applied to the galley/lavatory drain masts anytime there is aircraft electrical power on the aircraft?

A22.  Yes.

Q23. When are the windshields and side windows heated automatically on the ground?

A23.  Window heating comes on automatically when at least one engine is running.

Q24. What would happen if the RAIN RPLNT pushbutton was pushed on the ground with the engines shut down?

A24.  The RAIN RPLNT p/b is inhibited on the ground with the engines stopped.
