Information

This model extends the AircraftBase model and contains the parameters of Hawker Siddeley HS-121 Trident 3B.

The values of moments and the xz-product of inertia are guessed based on the known aircraft size and mass.

Due to the special propulsion configuration of the aircraft, a custom propulsion model is built to this model.
