What piece of information follows the clearance symbol on a departure strip?

The clearance symbol on a departure strip is typically followed by a dash and additional information that confirms the clearance details provided to the aircraft. This could include various instructions that guide the pilot's actions immediately after takeoff, contributing to smooth and safe operations.

In air traffic control operations, this additional information is crucial for effective communication and ensuring that all parties are aware of the specifics regarding the flight's clearance. While elements like estimated altitude, contact frequency, and direction to hold are important for overall flight operations, they are not standardized as the immediate follow-up to the clearance symbol. The dash and accompanying information signify that the clearance has been understood and is being followed correctly.
