On newer engine installations, the logic is more sophisticated (e.g. rate of decel of N2/N3) and we've certified auto-relight to be equivalent to con ignition for all engine types and gotten rid of the con ignition function entirely.
Does that help?
Absolutely ))
By
newer engine installations, would this include retrofitting 747-400's .. or is this for next gen aircraft... 747-8, 787, etc.
Much appreciated.
Cheers
