If ATC issues a new heading off a DP transition with no extra information, the DP is considered canceled.

• A. True
• B. False
• C. Only if the new heading is to the left
• D. Only if you acknowledge

Answer: (A)

When ATC assigns a new heading off a DP transition, you are no longer following the published departure procedure. The controller is taking control of your navigation path, so the DP is canceled automatically. You should fly the issued heading and follow any further ATC instructions, rejoining the DP only if ATC clears you to do so. This aligns with why the statement is true: a new heading given without additional instructions means you’re being vectored, not continuing the DP. It doesn’t depend on turning left, and you don’t need to acknowledge for the cancellation to take effect.
