Enroute climb penalty as per MEL B777
 

Dear All

Many MEL's mention about this table. Questions specific to the table (not the MEL Item) are -

Q1) what is the approximate maximum lift-to-drag ratio speed ?
Is it the one on the E/O CRZ page on FMC? If yes where is it given.

Q2) to account for difference in level off altitude, cruising at for eg 320kts (with a dispatched MEL & follow by inflight engine shut down)
How do I add this weight penalty & get a lower ceiling?
Should I add the penalty to a/c weight to get a lower ceiling?
Will modifying ZFW in PERF page help?
