ED Decision 2026/006/R
FUNCTIONS AND SUBJECTIVE TESTS — SUGGESTED TEST ROUTINE
(a) During initial and recurrent evaluations of an FSTD, and when deemed relevant in the event of a major modification to an FSTD, the competent authority should conduct a series of functions and subjective tests that together with the objective tests complete the comparison of the FSTD with the type, variant or group of aircraft, as applicable.
(b) The FSTD should provide adequate flexibility to permit the accomplishment of the desired and required tasks while maintaining an adequate perception by the flight crew that they are operating in a real aircraft environment. Additionally, the instructor operating station (IOS) should not present an unnecessary distraction from observing the activities of the flight crew whilst providing adequate facilities for the tasks.
(c) The competent authority should perform sampling of the functions and subjective tests that are applicable to the device. Part of the subjective test routine for an FSTD should involve an uninterrupted fly-out and a flight where the FSTD controls such as flight freeze and repositioning are used. The evaluator(s) should brief the persons participating in the evaluation on the planned flight contents and working methods.
