Description

Desired capability or behavior.

GASP engine pod mass is a combination of pylon and nacelle mass only. In FLOPS, engine pod mass includes everything inside the pod too (so nacelle/pylon plus engine, fraction of electronics, hydraulics, fuel system, etc.) The same Aviary variable can't be used for both definitions, so one needs to be chosen (and whether it's worth tracking both values separately).

Note about this in mass/gasp_based/fixed.py

Research direction

Start in mass/gasp_based/fixed.py, read the existing note and trace how the GASP engine pod mass and FLOPS pod mass definitions are represented. Determine whether one definition should be selected or both tracked, then update the relevant implementation and documentation so the chosen meaning is unambiguous and verify affected mass calculations.
