*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 level 5 requires aerodynamic programming and systems modeling, but it may represent a family of aircraft rather than one specific type of aircraft model.
The FTD Level 5 version is specific to a class of aircraft (S/E, M/E, etc) and meets a specific FTD design criteria (as published in 14 CFR 60).
