*It is important to note that many simulators may contain specific features or abilities not explicitly stated in their level of certification. Every simulator, especially custom built designs, are able to be customized in order to fit any facility needs even if a desired level of certification does not necessarily require it. Any ambiguities with respect to the capabilities of the simulator are finalized in the sales contract and technical specifications document prior to the simulator deal closing.
The FTD is broken down into four categories, the Level 4, 5, 6, and 7. The FTD Level 7 is a model specific certification, used for helicopters only. All applicable aerodynamics, flight controls, and systems must be modeled. A vibration system must also be supplied, and a visual system is required at this level.
