What is the lower MSL altitude limit of Class E airspace at TBR?

The lower limit of Class E airspace typically varies depending on the specific requirements of the airspace and the surrounding airspace classifications. In many cases, Class E airspace begins at either 700 feet or 1,200 feet above ground level (AGL), but certain areas, particularly those surrounding airports, may have Class E airspace that begins at a lower altitude.

For TBR (Tampa, FL), the Class E airspace is often designed to accommodate instrument approaches, transitions, and operations for surrounding air traffic. In such airport areas, the lower limit of Class E airspace is often established to provide safe vertical separation from the airspace below, which might be Class G airspace.

In this case, the lower limit of Class E airspace at TBR being 887 feet MSL indicates it is configured to effectively accommodate both the needs of local air traffic and to align with the operational requirements of nearby aviation facilities. This altitude is above typical Class G transition altitudes and helps in maintaining safety and separation during takeoff, landing, and in the vicinity of the airport. Understanding this altitude is crucial for flight operations in the area, as it plays a key role in ensuring that aircraft operate safely without conflicting with other airspace users
