Flew in from Florida yersterday and after a night in the Mess and a little Carribean hospitality
its 0500 hrs and time to get the show on the road. Thumbs up from the engineer in the Maintenance hanger that she's serviceable, refuelled and good to go, crew briefing at 0530, ETD 0600, flight time approx 10.5 hrs (phew, I'll be landing on vapours). This may take a little work. I'll post flight stats, fuel usage etc..on arrival, fingers crossed....
The B-17G Accu-Sim will make 10.5 hours in the air easily. I've flown it beyond 12 hours in the past, hopping around the
Pacific Ocean and flights across the South Atlantic.
What you need to be mindful of is oxygen. On flights that I think will be over 8 or 9 hours in length I stay at or below 12,000'
for the first 2 hours of flight before climbing higher and going on oxygen. You could climb early but then descend early when
your oxygen gets critical on the other end but in that scenario you will need ot be mindful of the oxy state after flying for
9 hours and in a less than alert state of mind
On the flights where I have had to load the bomb bay tanks, I keep the tokyo tank valves closed and burn fuel from the
main tanks initially. Once there is enough "room" in the mains I start transferring fuel from the bomb bay tanks to the
mains in "steps"....50 gal from right BB tank to #1 tank, 50 gal from left BB tank to #4, 50 gal from right BB tank to
# 2, 50 gal from left BB tank to #3.
I repeat that procedure until the nBB tanks are empty and then jettison them, thus eliminating 900 pounds of dead weight.
Just be careful that you do not run the transfer put on a "dry" tank or you will burn it out!
The above also gives you something to do
Once the BB tanks are dropped, then I open the valves for the tokyo tanks until they are dry.
