Simple Flight Model vs Advanced Flight Model

The game engine has limits. The “simple flight model” aka SFM is only supports some animation sources. The Advanced Flight Model aka AFM, supports far more. Therefore some things work in AFM and not SFM etc. The biggest differences are in:

Speed control and limits
Damage model fidelity
Flight model and Handling setup/limits
PhysX and behaviour on roadways
Lift and power
Torque indicators on the MFD Dispays
RPM indicator on the MFD Dispays

Game Engine Limits

Issue	Simple Flight Model	Advanced Flight Model
Rolling Landings	NO	Yes - ensure the wheel brake is off and only touch down ~50kph. You will be able to to taxi the aircraft with gentle pressure on the cyclic.
Overspeed	NO	Yes - Over 300Kph the main rotor will become ineffective and either cause damage or lose lift falling out of the sky.
Tail Rotor Damage	Yes, only via hit point of impact damage	Yes - Sa with SFM but with the added threat of over torquing the tail rotor by apply too much rudder at high speeds.
