Phase 2 of initiating a 135 trip involves which action?

• A. Scheduler confirms the trip and briefs T2.
• B. T1 Controller validates and designates the trip.
• C. T2 personnel reviews the trip and accepts the brief in FOS.
• D. Scheduler releases the trip in FOS.

Answer: (B)

In Phase 2 the focus is on making sure the trip data are correct and ready to move to the next stage. The T1 Controller verifies all the key details—aircraft, routing, times, crew pairings, fuel, special handling, and any other notes—and then designates the trip to the next step in the workflow. This designation hands off responsibility to the next party (T2) so they can proceed with briefing and further actions.

Why the other steps aren’t Phase 2: having the scheduler confirm the trip and brief T2 is typically an earlier or different step in the process, since it involves initial confirmation and communication. T2 reviewing the trip and accepting the brief happens after the trip has been designated and briefed for execution, i.e., a later phase. Releasing the trip in the flight operations system generally occurs once all prior validations and preparations are complete, which is also later than Phase 2.
