Whoever feels lucky feel free to check if the IGN sw works in dual GEN FAIL situation at all...
FADEC monitors N2 when a sub idle condition is detected for 30 seconds it attempts relight with both igniters and changing fuel flow. If it doesn't succeed then ignition is switched off. After that it will come on for the dead engine when engine master is put on again as in during relight. Same thing should happen in dual flame out case. Ignition is the fourth item in the check list. EMER GEN comes on automatically you just ensure if not then put manually on, thrust levere are brought to idle to prevent surges, FAC reset to get rudder trim and then engine mode selecor to ignition. If engine is not recovered by then, you will have to wait till the envelope to put masters off and on after 30 seconds ignition will come on.
