max FL, and vref30 rule of thumb
Nice thread,
Here are mine, correct me if I'm wrong
B777-200
Max FL under all circumstances B772 rule of thumb FL600-GW, so weight 300 tons= max FL 300.
n-1 max FL rule of thumb FL450-GW, so weight 250tons, max n-1 FL200 drift down altitude
MAX TOW n-1 driftdown FL150 under most circumstances possible.
MAX TOW n-1 after take off climbing , max FL120.
go arround fuel 400kg till 1500ft
Vref30= GW/3 +66kts, so vref30 210 tons=210/3=70 +66+ 133kts..
Jettison time to standpipe level from full wing tanks and ctr tank less then 45 tons= arround 40 minutes.
Every 10 tons more in ctr tank= add 10 minutes.
who is next ?.....
