Flashcards in ANTI ICE Panel Deck (16):
Is the engine anti-ice part of the normal pneumatic system?
No – it is a separate system independent of the pneumatic ducting
When do you use engine anti-ice?
When OAT (Ground) / TAT (Flight) 10° C or below with visible moisture present. Visible moisture includes fog
with visibility ≤1 mile, rain, snow, sleet or ice crystals; it also includes standing water, slush, ice or snow on the
taxiway and/or runway(COM 3.201.2)
• Prior to and during descent in icing conditions (including temperatures below –40° C SAT)
What is the exception to the engine anti-ice rule?
During climb and cruise when the temperature is below –40° C SAT
What does a FAULT light in the ENG ANTI ICE pb indicate?
Switch/anti-ice valve disagreement
With both engine bleed valves close, is Engine Anti-ice still operational?
With ENG ANTI ICE ON what indications will you see?
• Blue ENG ANTI ICE light ON
• ECAM: ENG ANTI ICE
• ECAM: IGNITION
• N1 limit is reduced (amber tick on N1 indicator)
• N1 idle is increased
What should you do if there is significant engine vibration on the ground due to ice?
Increase N1 to 70% for a minimum of 15 seconds prior to selecting a higher thrust
With engine anti-ice ON, is your descent affected?
Yes, because idle thrust is increased
Can you use the wing anti-ice on the ground?
It is not permitted to select wing anti-ice on while on the ground
What happens if you turn the wing anti-ice switch on the ground?
The wing anti-icing valves will open for a 30 second test
What part of the wing is heated?
Outboard 3 slats
When do the wing anti-ice valves automatically close?
• On landing
• Bleed leak detected
• Loss of electrical power
Can you use the APU bleed for wing anti-ice?
What does the amber FAULT light in the WING ANTI ICE pb indicate?
• Position of the anti-icing control valve is not in the required position
• Low pressure is detected
In what position do the Wing and Engine Anti-Ice valves fail if electrical power is lost?
• Wing – valves CLOSE
• Engine – valves OPEN
