Which option is NOT listed as a Part 91 flight type?

• A. Training
• B. Mx ferry flights
• C. Commercial transport
• D. Demonstration/Familiarization

Answer: (C)

Under Part 91, flight types describe activities that fall under general operating rules for non-air-carrier operations. The categories you’ll see include training flights, maintenance ferry flights (moving an aircraft after maintenance), and demonstration/familiarization flights (such as manufacturer demos or familiarization with a new aircraft). These reflect operations where the flight is not conducted for hire or air carrier purposes.

Commercial transport—carrying passengers or cargo for compensation or hire—is not one of these Part 91 flight-type categories. That kind of operation is regulated under other parts of the rules, such as Part 121 for airline-style scheduled service and Part 135 for on-demand charter. So it isn’t listed as a Part 91 flight type, which is why it’s the correct choice for what is NOT listed.
