A320 Eng AI & IGN
Hi,
I remember seeing this during my rating but haven't seen it since.
Firstly, is it correct that with the engine anti ice on you get continuous ignition? Ie no need to switch eng mode selector to IGN if you need it.
If this is correct can someone please point me to an FCOM reference.
Many thanks

Hello...
in our A320 equipped with CFM56-5B...when you use the engine anti-ice...you will not have automatic selection for the ignition system .
Reference FCOM 1 chapter 70 section 80 page 3 (1.70.80) look at the bottom of the page at the automatic selection.
Good Luck.

Sorry, but I think EIU switch ignition on automatically, when ENG A/I pb. pressed on 56-5B. If I remeber, active ignition is not displayed on ECAM in this case. Maybe depends on A/C modification.

Page 1 (1.70.80 P1) GENERAL has
ENG MAN START and ENG 1(2) ANTI ICE pushbuttons as inputs to the
Engine Interface Unit (EIU) which controls
ECU and FADEC which contols the igniters.
But not displayed on ECAM. So since the ECAM is the pope when it comes to infalliblity, you will have to check with your engine mod to see if the igniters are indeed firing or not!
But jetjock is correct - chance of flameout very unlikely with today's engines. You need three nozzles of foam fired into the engine to flame it out. Not enough water or ice in a red thunderstorm cloud to do this.
