# §121.407. Training program: Approval of flight simulation training devices.

- (a) Each FSTD used to satisfy a training requirement of this part in an approved training program, must meet all of the following requirements:
  - (1) **Be specifically approved by the Administrator for—**
    - (i) Use in the certificate holder's approved training program;

    - (iii) **The particular maneuver, procedure, or flightcrew member function involved.**
  - (2) Maintain the performance, function, and other characteristics that are required for qualification in accordance with [part 60](/cfr/14/part60.md) of this chapter or a previously qualified device, as permitted in accordance with [§ 60.17](/cfr/14/60.17.md) of this chapter.
  - (3) Be modified in accordance with [part 60](/cfr/14/part60.md) of this chapter to conform with any modification to the airplane being simulated that results in changes to performance, function, or other characteristics required for qualification.

- (d) An FFS approved under this section must be used instead of the airplane to satisfy the pilot flight training requirements prescribed in the certificate holder's approved low-altitude windshear flight training program set forth in [§ 121.409(d)](/cfr/14/121.409.md?p=d) of this part.
- (e) An FFS approved under this section must be used instead of the airplane to satisfy the pilot flight training requirements prescribed in the extended envelope training set forth in [§ 121.423](/cfr/14/121.423.md) of this part.
