How many minutes after departure is ATCT authorized to advise aircraft to expect requested altitude when ARTCC releases to interim altitude?

When air traffic control towers (ATCT) advise aircraft to expect their requested altitude after being released to an interim altitude, the standard time frame is typically around 10 minutes after departure. This timeline allows controllers to properly manage air traffic and ensure that the aircraft has had sufficient time to climb to the interim altitude while also maintaining appropriate separation from other aircraft.

The 10-minute guideline ensures that the tower is able to coordinate effectively with the terminal and en-route air traffic systems, providing a balance between managing traffic safely and accommodating pilots’ requests for altitude changes. Understanding these operational procedures is crucial for ensuring safety and efficiency in air traffic management.
