Configuration Deviation List (CDL)

[DoMePlease]

Some configuration deviations require a reduction in Performance Weights. How does one apply an "Enroute Climb" performance weight penalty?

[411A]

Weight vs altitude and cruise buffet onset margin.
IE, reduced weight allowable to climb higher.

This could also affect driftdown ability in the event of an engine failure/shutdown, which it turn could affect the flight planned route for dispatch.

Unless of course you might be in BA, in which case they press on with three...regardless.

[Intruder]

There is no such penalty listed in the 747 CDL. What airplane has it listed? What do the explanations say in the front of the CDL?
