If you are flying a DP, the controller gives you a new heading that takes you off the Departure Procedure transition without any additional info; is the DP considered cancelled?

• A. Yes
• B. No
• C. It remains active until you reach the transition
• D. It depends on weather

Answer: (A)

When you’re on a Departure Procedure, being given a new heading that takes you off the published transition with no instruction to continue the DP means the DP is cancelled. ATC is taking control of your heading, and you’re no longer following the published route. You should fly the heading ATC gave and don’t try to continue the DP unless ATC clears you to do so. Weather doesn’t affect this; cancellation isn’t weather dependent. The DP would remain active only if you were explicitly cleared to continue on the DP or to rejoin the transition.
