Which airspace is defined as a transition area when in conjunction with an airport with a prescribed IAP?

The correct choice pertains to Class E airspace that extends from 700 feet AGL. This classification of airspace is often utilized as a transition area in conjunction with airports that have a prescribed Instrument Approach Procedure (IAP).

Class E airspace from 700 feet AGL typically serves to protect the approach and departures of aircraft near an airport, facilitating instrument flight rules (IFR) operations. It effectively provides a controlled environment for aircraft transitioning to or from the airport, ensuring that both IFR and visual flight rules (VFR) operations can occur safely in the vicinity of the airport.

In contrast, while Class D, C, and B airspaces have specific regulations and requirements related to their use, they serve different purposes and have distinct operational characteristics. For example, Class D airspace is primarily designed around smaller airports with operational control towers, while Class C airspace covers larger airports requiring more advanced communication between pilots and air traffic control. Class B airspace is the most restrictive and is typically associated with major metropolitan areas and their surrounding airports. However, none of these classifications specifically highlight the transition role that Class E airspace plays in the context of IAPs at airports.

Thus, the designation of Class E airspace from 700 feet
