Which document identifies the required equipment and operating procedures for Part 135 operations?

• A. Weather chart
• B. MEL
• C. Pilot logbook
• D. Ops Specifications

Answer: (D)

The key concept here is that Part 135 operations are defined by the operator’s Ops Specifications (OpSpecs). These FAA-issued documents lay out exactly what equipment must be on the aircraft and which operating procedures the crew must follow for the authorized operations. OpSpecs tie to the certificate holder and specify the aircraft types, routes or airports, and the required equipment and procedures for those operations, and they can be updated as the operation changes.

An MEL is a maintenance document that lists items that may be inoperative under certain conditions; it does not define the baseline required equipment for operations. A weather chart is used for planning and tracking weather, not for detailing equipment or procedures. A pilot logbook records flight time and currency, not the operational requirements of Part 135.
