Aviary mass-balance does not account for fuel used during take-off. #256

Closed Kenneth-T-Moore closed 4 months ago

Kenneth-T-Moore commented 5 months ago

Description

For height-energy and flops-based mass, the mass residual is computed based on the fuel burned, which is measured between the start of climb and the end of descent. When simplified takeoff is enabled, the fuel consumed therein is not added to the fuel burn. This results in a slightly lower gross weight when the aircraft is sized.

Example

This occurs when simple take-off is enabled in the phase-info.
