GROSS WEIGHT AND C.G. LIMITATIONS
1.
Gross weights:
2.
Maximum takeoff and landing weights may be further restricted by runway selection, weather conditions, abnormal aircraft configurations, minimum equipment list, configuration deviation list, center of gravity limits, and fuel density.
3.
The airplane configuration specified in Section 4 of this manual for various flight profiles is the configuration on which the allowable weights shown in the airport analysis section of the Weight and Balance manual are based. The prescribed configuration must be used to assure the aircraft performance requirements are met.
4.
Compliance with the center of gravity limits is assured by operation under an approved load planning system.
5.
If landing weight exceeds the values prescribed by Quick Turn Around Weight Limits chart, examination of the wheel thermal plugs and a waiting period of 27 minutes is required before a subsequent takeoff unless procedures are followed using the brake temperature monitoring system or the pyrometer measuring system.
