Types of Echo Airspace SETVODA
Surface
- To quality for a Class E surface area, the airport must have weather observation and reporting capability, and communications capably must exist with aircraft down to the runway surface.
- A Class E surface area may also be designated to accommodate part-time operations at a Class C or Class D airspace location (for example, those periods when the control tower is not in operation)
- Pilots should refer to the airport page in the applicable Chart Supplement U.S. for surface area status information.
Dimensions
- From SFC up to adjacent or overlying controlled airspace or up to 17,999ft MSL
Depicted
Extension
Designated as extensions to Class B, Class C, Class D, and Class E surface
Dimensions
- From SFC up to the overlying controlled airspace

Special Use Airspace SUA
This is the designation for airspace in which certain activities must be confined, or where limitations may be imposed on aircraft operations that are not part of those activities.
Prohibited Area
Prohibited areas contain airspace of defined dimensions within which the flight of aircraft is prohibited. Such areas are established for security or other reasons associated with the national welfare. (National security)
- The area is charted as a “P” followed by a number (P-40).
Restricted Area
Restricted areas are areas where operations are hazardous to nonparticipating aircraft and contain airspace within which the flight of aircraft, while not wholly prohibited, is subject to restrictions.
- The area is charted as a “R” followed by a number (R-4401).
- Clearance must be obtained before entering these areas.
Warning Area
Warning areas are similar in nature to restricted areas; however, the United States government does not have sole jurisdiction over the airspace. A warning area is airspace of defined dimensions, extending from 3 NM outward from the coast of the United States, containing activity that may be hazardous to nonparticipating aircraft.
- The airspace is designated with a “W” followed by a number (W-237).
MOA Military Operations Areas
MOAs consist of airspace with defined vertical and lateral limits established for the purpose of separating certain military training activities from IFR traffic. Used to separate military and civilian operations.
- Clearance is not needed under Visual Flight Rules.
Alert Areas
Alert areas are depicted on aeronautical charts with an “A” followed by a number (A-211) to inform nonparticipating pilots of areas that may contain a high volume of pilot training or an unusual type of aerial activity. Pilots should exercise caution in alert areas.
Controlled Firing Areas - CFAs
Contain activities which, if not conducted in a controlled environment, could be hazardous to non-participating aircraft.
- Activities are suspended immediately when spotter aircraft, radar or ground lookout positions indicate an aircraft might be approaching the area. CFAs are not charted.
- They are not depicted in the chart
National Security Area - NSA
Airspace of defined vertical and lateral dimensions established at locations where there is a requirement for increased security and safety of ground facilities. Pilots are requested to voluntarily avoid flying through the depicted NSA. When it is necessary to provide a greater level of security and safety, flight in NSAs may be temporarily prohibited by regulation under the provisions of 14 CFR 99.7.
Other Use Airspace Areas
- Local airport advisory (LAA)
- Military training route (MTR)
- Temporary flight restriction (TFR)
- Parachute jump aircraft operations
- Published VFR routes
- Terminal radar service area (TRSA)
- National security area (NSA)
- Air Defense Identification Zones (ADIZ) land and water based and need for Defense VFR (DVFR) flight plan to operate VFR in this airspace
- Intercept Procedures and use of 121.5 for communication if not on ATC already
Temporary Flight Restrictions - TFRs (AC 91-63)
It is a regulatory action issued via the Flight Data Center (FDC) Notice To Airmen (NOTAM) to give some separation of the traffic from an airspace
Are 2 big reasons to create a issue a TFR
- Presidential and other public figures TFR 14CFR 91.141

- Air show 14CFR 91.145
- Stadiums 14CFR 99.7
- Disaster-Hazard Areas 14CFR 91.137
- Space Flight 14CFR 91.143
Obtaining Special Use Airspace Status
- Pilots can request the status of a SUA by contacting the using or controlling agency.
- The frequency for the controlling agency is tabulated in the margins of the applicable VFR and IFR charts
- Pilots should check ARTCC NOTAMs for airspace activation
