What should you not issue when providing a cruise clearance at an airport without an IAP?

• A. Recommended altitude change
• B. Crossing restriction
• C. Departure clearance
• D. Enroute clearance

Answer: (B)

When providing a cruise clearance at an airport without an Instrument Approach Procedure (IAP), it is crucial to ensure that the clearance issued does not include a crossing restriction. This is because such restrictions are typically associated with instrument approaches and defined procedures that guide an aircraft in a controlled manner towards a landing. At airports without an IAP, there are generally no specific routes or altitudes designated for an aircraft to follow, making it inappropriate to impose crossing restrictions. In contrast, recommended altitude changes, departure clearances, and enroute clearances can still be effectively provided without relying on an IAP. Recommended altitude changes help optimize flight levels for safety or efficiency, a departure clearance permits an aircraft to take off, and enroute clearances guide the aircraft during its flight towards its destination. However, crossing restrictions imply a need for specific route adherence that does not apply in environments lacking formal procedures.
