Is it permissible to have a published ramp weight that exceeds the published maximum takeoff weight?

The rationale behind allowing a published ramp weight that exceeds the published maximum takeoff weight relates to the understanding of how weight changes during the pre-flight and taxi phases. The ramp weight includes everything on the aircraft: fuel, passengers, cargo, and the aircraft itself when it is at the ramp. Since aircraft often burn fuel while on the ground before takeoff, the fuel weight decreases, which in turn reduces the overall weight of the aircraft prior to reaching the takeoff phase.

Therefore, it’s permissible for the ramp weight to initially exceed the maximum takeoff weight as long as the aircraft is expected to burn enough fuel while taxiing to bring its weight within the specified limits before the actual takeoff. This understanding allows for operational flexibility while ensuring that the aircraft meets safety and performance requirements before leaving the ground.

This context highlights the importance of carefully monitoring weight and balance, as exceeding maximum takeoff weight at any time could compromise the aircraft's structural integrity and safety.
