What does the acronym SETVODA refer to concerning Class E airspace types?

The acronym SETVODA pertains to the various types of Class E airspace and is a handy mnemonic for remembering these categories. The correct breakdown includes Surface, Extension, Transition, Victor Airway, Offshore, Domestic En Route, and Above 14500 MSL. Each component of this acronym represents a specific type of Class E airspace and encompasses diverse situations where this airspace is utilized.

To provide a clearer understanding:

• Surface: This refers to Class E airspace that begins at the surface of the earth, typically around some airports and serves as a zone where instrument flight rules (IFR) may apply.
• Extension: This indicates airspace that extends from the surface, commonly used for approaches and departures related to certain airports.
• Transition: This type is used for the airspace that allows for transitions to and from the en route phase of flight.
• Victor Airway: This refers to specific routes used for IFR flights, which navigate between navigational aids at lower altitudes within Class E airspace.
• Offshore: This designation is used for airspace extending from the shore out to a specified distance over water where specific air traffic rules apply.
• Domestic En Route: This indicates areas of airspace used
