FAR 61.4 — Simulator and FTD Approval
FAR 61.4 explains how flight simulators and flight training devices must be qualified and approved by the FAA for training, testing, and checking credit.
FAR 61.4 governs when a flight simulator or flight training device (FTD) can be used to satisfy training, testing, or checking requirements under Part 61. This matters because logging credit toward a certificate or rating in a ground-based device is only valid if the device is properly approved.
The rule requires that each simulator or FTD be qualified and approved by the Administrator for:
- The specific training, testing, and checking it's being used for;
- Each maneuver, procedure, or crewmember function performed in it; and
- The category, class, type, or variation of aircraft it represents.
Two exceptions apply:
- Pre-1996 devices: Any device accepted or approved by the FAA before August 1, 1996 is treated as an FTD, as long as it still functions as originally designed and is used only for the purposes originally approved.
- Other devices: The Administrator may approve a device that isn't a full simulator or FTD for specific limited purposes.
Operationally, this means you can't just log time in any sim — the device and its approval letter must match the credit you're claiming.
