FTD
Flight Training Device
An FTD replicates the cockpit of a specific aircraft type, including its avionics, switches, and systems behavior. Unlike an AATD, an FTD is qualified to a numbered FAA level (Level 4 through Level 7) that determines how much training credit it can count toward certificates and ratings. Higher levels allow more hours to be logged and can substitute for more categories of required training.
Finding an FTD at a Part 61 flight school is uncommon. They are expensive to build and certify, and are typically found at larger Part 141 schools or airline training centers. If a school offers an FTD, it usually supports a specific instrument or commercial curriculum and can significantly reduce the total cost of the rating by substituting device hours for more expensive aircraft time.
Common examples: Frasca 142, Redbird MCX, CAE Cessna 172
