What is the altitude for high key position on approach?

The high key position on approach is typically aligned with an altitude of 3000 feet above ground level (AGL). This altitude is established to provide sufficient spacing and safety margin for aircraft during a maneuver that prepares for landing or for the subsequent low key position, which is lower and more aligned with the final approach. At this altitude, pilots can effectively manage their descent and troubleshoot any problems before reaching the critical stages of landing.

Using 3000 AGL allows pilots enough time and altitude to plan their descent and make necessary adjustments to ensure a stable approach to the runway. It also provides a buffer against terrain and obstacles, helping to maintain safe operating practices during the critical phases of flight.
