If a SID has been (or will be) assigned with the _______________ published on it, then it may be omitted from a clearance.

If a SID has been (or will be) assigned with the _______________ published on it, then it may be omitted from a clearance.

• A. arrival speed
• B. departure control frequency
• C. runway heading
• D. altitude restrictions

Answer: (B)

The key idea is that a SID can include the frequency to contact ATC after departure. When that departure control frequency is already published on the SID chart, air traffic control can omit saying the frequency in the clearance because the pilot already has the exact frequency to contact in hand. The pilot will switch to that published frequency for the departure handoff and proceed with the rest of the clearance, such as the route and any altitude or speed restrictions. So, the reason this choice is best is that it leverages information already provided on the chart to streamline the clearance and ensure the correct communications path after takeoff. The other items—arrival speed, runway heading, and altitude restrictions—are operational details that are either already part of the SID itself or not specifically about the handoff frequency, so they don’t justify omitting the clearance’s frequency.
