Bilbo, we're not talking about retarding the condition lever to low idle whilst in flight, we were meaning leaving it there all the time, the only effects will be greater discing effect and longer to spool up when needing reverse.
by saying that it is barely self sustaining you made it sound like the flame was at risk of being blown out while low idle is selected......when maybe you meant the pilot is at risk of shutting the engine down by mistake.....is that what you meant?
