Federal Aviation Regulations Practice Test 2025 – Complete Exam Prep

The regulation covering flight operations for on-demand charters is Part 135. This part of the Federal Aviation Regulations specifically addresses the requirements for commuter and on-demand operations, which include charter flights. It outlines the operational standards, maintenance requirements, and pilot qualifications needed for these commercial operations, ensuring a high level of safety and regulatory compliance for passenger and cargo services.

In contrast, Part 121 pertains to scheduled air carrier operations, which is distinct from on-demand services. Part 145 deals with repair stations and the maintenance aspect of aviation but does not cover flight operations. Part 91 addresses general operating and flight rules for all aircraft, including private and recreational use, but again does not specifically cover the regulatory framework for on-demand charter services. Thus, Part 135 is the correct reference for the regulatory requirements related to on-demand charters.
