Doing some research into how Moments of Inertia affects the FlightModel in the MSFS2020 Aircraft, I stumbled onto a weird case of confuse Moment of Inertia Attribution.

In the Flight_Model.cfg it is stated:

"

empty_weight_pitch_MOI = 60000 ; Empty pitch moment of inertia, Jxx (SLUG SQ FEET)

empty_weight_roll_MOI = 13760 ; Empty roll moment of inertia, Jzz (SLUG SQ FEET)

empty_weight_yaw_MOI = 30090 ; Empty yaw moment of inertia, Jyy (SLUG SQ FEET)

"

But this is not a correct mathematical convention, at least to the material I Have? They state that

**Ixx = Moment of Inertia for Roll**

**Iyy = Moment of Inertia for Pitch**

**Izz = Moment of Inertia for Yaw**

Regards!
