A departure control frequency may be omitted in a clearance if____________

• A. Frequency is published on an assigned/given DP
• B. No clearance is needed
• C. The departure is behind schedule
• D. The pilot requests omission

Answer: (A)

When a departure procedure already publishes the departure control frequency, that frequency is the one to use and it’s understood by both the pilot and ATC. Including it in the clearance would be redundant, so it may be omitted. The DP serves as the source of truth for who to contact and on what frequency once you’re on the departure, keeping clearances concise and avoiding confusion.

Other options don’t fit because a clearance is still needed to authorize the flight, the schedule has no effect on how frequencies are assigned or communicated, and pilot requests to omit a frequency do not override standard procedures.
