Which statement about differences/transition training is true?

• A. It is not required for any changes to aircraft type.
• B. It is required only when upgrading to an unrelated, completely new type.
• C. It is required when moving to a different, but related type where airframe knowledge has changed.
• D. It is the same as an initial type rating.

Answer: (C)

Differences/transition training is about bridging knowledge when you move to a different aircraft type that is related but not identical, and where the airframe has changes that affect how you operate it. This training is required specifically when the new type is related but different enough that airframe knowledge has changed, so you can safely apply procedures, systems, and performance differences in flight. The correct statement captures this nuance: you don’t need it for every type change, you don’t only need it for completely unrelated new types, and it isn’t the same as an initial type rating, which covers the first-time authorization to operate a new type.
