DAP Policy 106: Harmonisation of Transition Altitude in Controlled Airspace

We would like to hear from you

The CAA is committed to improving how we deliver services, please help us by completing a short survey about your experiences today

The Transition Altitude (TA) is the altitude at or below which the vertical position of an aircraft is controlled by reference to altitudes. The vertical position of aircraft at, or below, any Transition Altitude will normally be expressed in terms of Altitude. The vertical position at, or above, any Transition Level will normally be expressed in terms of Flight Level. When descending through the Transition Layer the vertical position will be expressed in terms of Altitude, and when climbing in terms of Flight Level.
