This information allows aircraft to safely transition from the enroute airway segment (which provides guidance for safe flight between the flight origination and destination) through the terminal environment (where aircraft transition from the enroute airway segment to the airspace in the immediate vicinity of the airport) to a safe landing on the designated runway.

The middle briefing strip includes procedure notes, the approach lighting system, and the missed approach procedure text. The bottom briefing strip includes communication information.

Because of the importance of maintaining up-to-date information about the often changing environment around airports (e.g., vertical obstructions to air traffic, such as cranes, can be erected at short notice), approach plates are published with expiration dates and are reviewed on a frequent basis.
