Greetings all,
   I'm slowly going through the missions and A/Cs which have problems that defy my best resolutions.

May I ask assistance on this one?

The mission is called 'Save the Lancasters'.
On take-off I can see +6lbs boost max. After warping (if I wait for the 500-odd miles to meet the Lancs I feel I may die of old age) all I see is -4lbs. I barely stay in the air.
I have replaced the sound file, no change- (all RAF single engine A/Cs have the same one aliased) and there is no similar problem in any other mission I have found yet. Just 'Save the Lancasters'.
It must be coming from the mission...Illogical?!
Can the mission dictate engine boost?
Not being au fait with the inner workings of missions, I have no idea where to go from here.

Any wisdom will be gratefully accepted.

Many thanks in advance.

Crikey H, I never thought of that! I have warped a thousand times and never had the problem before. This is a '300-odd miler' until you arrive at the combat zone but it didn't cross my mind fuel could be a factor as the engine still runs. I do close the throttle before warping...mean I suppose but given the price of squirt here in England.......
In free flight yonks ago I once flew until fuel exhaustion and the motor stopped. Silence was NOT golden! Didn't walk away from that one. I'll reconfigure fuel load and try again.
Glad to know I can open a question when if you think a second about it I had the basic answer in my question.

Many thanks H.

Will report back.
