Editing Flight simulator (section)

=== European Aviation Safety Agency (EASA, ex JAA) categories ===

These definitions apply to both airplanes<ref name="CS FSTD(A).200">CS FSTD(A).200: Terminology</ref> and helicopters<ref name="CS FSTD(H).200">CS FSTD(H).200: Terminology</ref> unless specified otherwise. Training devices briefly compared below are all different subclasses of Flight simulation training device (FSTD).

'''Basic instrument training device (BITD)''' ''airplanes only'' : A basic student station for [[instrument flight]] procedures; can use spring loaded flight controls, and instruments displayed on a screen

'''Flight Navigation and Procedures Trainer (FNPT)''' : Representation of cockpit with all equipment and software to replicate function of aircraft systems
* '''EASA FNPT Level I''' :  Fully enclosed real-scale cockpit, control forces and travel representative of the aircraft,  aerodynamic model taking into account changes to airspeed, loading and other factors
* '''EASA FNPT Level II''' : Model handling of aircraft on ground and in [[Ground effect (aerodynamics)|ground effect]], effects of icing, visual system including different ambient lighting conditions (i.e. day, night, dusk)
* '''EASA FNPT Level III''' ''helicopters only'' : Wider field of view and means of quickly testing correct operation of hardware and software
* '''MCC''' : Additional requirements for FNPT Level II and III to be used for [[multi-crew cooperation]] training, for example which instruments need to be doubled for each crew member<ref>Appendix 1 to CS FSTD(H).300, Appendix 1 to CS FSTD(A).300</ref>

'''Flight Training Devices (FTD)'''
* '''EASA FTD Level 1''' : May lack a visual system, compared to FNPT the aircraft systems must operate correctly based only on pilot inputs without requiring instructor actions
* '''EASA FTD Level 2''' : Visual system with different conditions, cockpit must include other crew stations, controls must replicate movement dynamics
* '''EASA FTD Level 3''' ''helicopter only'' : Model data must be based on validation flights - cannot be generic aerodynamical model, wider field of view

'''Full Flight Simulators (FFS)'''
* '''EASA FFS Level A''' : Motion system with 3 degrees of freedom (pitch, roll, heave)
* '''EASA FFS Level B''' : Motion system with all 6 degrees of freedom, modelling ground handling
* '''EASA FFS Level C''' : Simulate different runway conditions, icing, more detailed aerodynamic model
* '''EASA FFS Level D''' : Characteristic vibrations that can be felt in the cockpit, realistic noise levels
