Which item is NOT included in a standard SID unless required?

• A. Separation
• B. Altitude
• C. ATIS
• D. Route

Answer: (B)

The key idea is what a standard SID actually provides: a published path from the runway to the en route structure, with the route itself defined. That route is always a part of the SID, outlining the specific turns and fixes to follow to get moving in the right direction.

Altitude, on the other hand, is not automatically fixed in every SID. It is included only when necessary to ensure obstacle clearance or to meet ATC requirements. If there’s no altitude restriction, you’ll typically be cleared to an altitude by ATC after departure rather than being constrained by the SID itself. ATIS is a pre-departure information broadcast and not part of the procedural path of the SID, and separation is managed by ATC rather than being a line item in the SID.

So altitude is the item that isn’t included by default in a standard SID unless required.
