Properly test mass-weight conversions in takeoff and landing #416

Open jkirk5 opened 5 days ago

jkirk5 commented 5 days ago

Desired capability or behavior.

simplified_takeoff.py and simplified_landing.py contain components that convert between mass and weight but in English units, meaning they use the GRAV_ENGLISH_LBM constant that currently is hardcoded to 1 (assumes standard gravity). Tests need to be made to ensure that the components are properly dividing and/or multiplying by this constant as necessary by setting the value to 1.1 and checking partials to ensure consistency.
