What should be specified when NOT included in the SID?

• A. Altitude
• B. Speed
• C. Aircraft type
• D. Destination

Answer: (A)

Altitude is what must be specified when the SID does not include it. SIDs outline the departure route and may include some ascent or speed constraints, but if no initial altitude is published on the chart, ATC must assign an altitude in the clearance to ensure proper vertical separation and safe climb from takeoff. The other items—speed, aircraft type, and destination—are not the primary vertical guidance that would be left to ATC to assign in the absence of SID specifics, and the destination is already part of the flight plan.
