What is the purpose of a Transition Area?

The purpose of a Transition Area is primarily to contain Instrument Flight Rules (IFR) operations. These areas are designated to manage air traffic during the transition from one type of airspace to another, specifically when aircraft are moving between enroute phases of flight and the terminal environment. This helps ensure that IFR flights, which rely on air traffic control for navigation, can operate safely and efficiently, especially in terms of altitude and proximity to other aircraft.

The Transition Area serves to provide a buffer that aids in the smooth integration of different types of aircraft operations, enhancing overall safety in mixed-use airspace. By clearly defining where IFR operations can take place, it mitigates potential conflicts with Visual Flight Rules (VFR) traffic, thereby maintaining order in busy airspace.
