Sadly it's longitudinal CofG which is where our examiner problem lies.
With a BEW 885 (830 sounds like a pipe dream in a Beta II!) at approx 103.4"
A combined crew of 400lbs at 78"
A main tank at 106.8"
An aux at 103.8"
Well, pretend you have no fuel to start with...
91509lbin
31200lbin
An arm of 95.49".
The forward arm limit at 1275 is 95.5". This proceeds backward to about 96.5" at MAUW 1370, in line with a normal fuel line, so irrespective of fuel added, you cannot now restore longitudinal CofG.
Note some of my numbers may be slightly off due to it being morning and me doing it from memory, but they tell the basic story.
We have a Beta I that has a BEW arm of 104.9, however it has no instrumentation in it at all, so he still can't get a pass!
I will try Elite, thanks for the idea.
