(h) Logging training time.
A person may log training time when that person receives training from an authorized instructor in an aircraft, full flight simulator, flight training device, or aviation training device.
The training time must be logged in a logbook and must:
(i) Be endorsed in a legible manner by the authorized instructor; and
(ii) Include a description of the training given, the length of the training lesson, and the authorized instructor's signature, certificate number, and certificate expiration date.
Consider a 4-seat airplane with flight controls for the front seats only. If there are two students on one flight and they go up with a CFI and neither one touches the flight controls can they both log the instruction time? Assume the CFI takes off and shows the students how to conduct various maneuvers and how to track an ILS glide slope. Can the student in the back log training time since they received training from a CFI in an airplane? I sent off a request for legal interpretation but they said it could take up to four months to get a response.
