Proposed amendments to the Flight Operations Requirements

Consultation has commenced on amendment to the Flight Operations Requirements (OTAR Parts 91, 125, 135, 121).

Further information is provided in:

Comments on these amendments should be sent by email to editor@airsafety.aero or by post to our office address and received by 12 August 2024.


The requirements of this Part cover operation and piloting of aircraft, the arrangements for the planning and preparation for flight, and the maintenance and equipment of aircraft.

All Part 91 requirements apply also to operations subject to OTAR Parts 121, 125 and 135 unless expressly stated: the text of Part 91 either applies as provided or as supplemented in the other applicable Parts. The exception to this is that each Subpart F (Instruments and Equipment) applies only to the aircraft contained within the scope of that OTAR Part.

Appendices associated with a specific requirement are contained within the Subpart (after the last paragraph in the Subpart). Appendices that are applicable to more than one requirement or Subpart are provided at the end of the OTAR Part.

The Rules of the Air (Schedule 4 of the AN(OT)O) are reproduced in Appendix D of Part 91 which, due to the limitations of this format, is contained in a separate document below. Similarly, Tables referred to in the OTAR text are provided in the separate Tables document below.

The Index document below will assist in locating paragraphs in the requirements.


Text in red indicates the significant additions and changes. Some other editorial corrections have also been made, although these have not been highlighted.
