Changes to the release must be jointly approved by the captain and dispatcher. Which of the following is included in that requirement?

• A. En route or arrival holding, Alt. change greater than 6,000 ft up to FL310, Alt. change greater than 4,000 ft above FL310, hourly fuel trend, and route deviations more than 100 nm
• B. Only weather changes
• C. Only fuel changes
• D. No changes require joint approval

Answer: (A)

Joint approval is required whenever a change to the flight release could impact safety margins, fuel planning, or how the flight will actually operate. The items included are all changes that can significantly affect how the flight proceeds and whether the original release still accurately reflects current conditions.

En route or arrival holding can change fuel burn and timing, and may require a revised plan to ensure adequate reserves and proper sequencing with ATC. Large altitude changes—more than 6,000 ft up to FL310, or more than 4,000 ft above FL310—affect performance, fuel usage, and airspace constraints, so they need coordination between the captain and dispatcher. An hourly fuel trend flags whether actual fuel consumption is diverging from the plan, which could erode reserves or push the flight into an unsafe situation if not addressed. Route deviations greater than 100 nautical miles substantially alter the flight path, weather exposure, and fuel needs, necessitating joint review.

Those elements together form the set that must be jointly approved, since they directly influence safety practices and compliance. Other choices focus only on weather or only on fuel or suggest no change is required, which doesn’t capture the full scope of changes that require collaborative approval.
