The flight to go from KSEA to SBGR is scheduled to leave tonite at midnight.

The flight will be done at CI 65 - M.798 - 303kts. initial CRZ FL310
will step up to max of FL390

In preparation, I determined my fuel burn to be 236.6 lbs per min. in CRZ FL350 at M.798. at CI 65
This is easy to do. Take your plane with a 1/2 fuel block and go to FL350
let the plane stabilize 15 minutes and read the FF of each engine on the ND. 7.1
Boeing says that # time 1000 will give you in lbs the burn over one hour.
for one engine. divide by 60 and then time 2 is the burn in lbs for one minute.
