What is a Class F airspace?
Class F Airspace is special use airspace and can be either restricted or advisory. Class F can be controlled airspace, uncontrolled airspace, or a combination of both, depending on the classification of the airspace surrounding it.
Where is class F airspace used?
There, class F airspace includes alert areas, danger areas, rocket ranges, restricted areas, forest fire restrictions, and military active areas. Special use airspace may be classified as Class F advisory or Class F restricted, for events like air shows or other such temporary impediments to navigation.
What do US pilots do with class F airspace?
The general use case for Class F airspace seems to be allowing IFR flights to operate in “uncontrolled airspace”.
Why is there no class F?
It’s their own adoption of it for what we call restricted airspace. ICAO class F airspace is UNCONTROLLED by definition. It differs from class G in that advisory ATC clearances are available (with some degree of IFR/IFR separation when “possible”).
What airspace is above FL600?
Class E airspace
Class E airspace typically extends up to, but not including, 18,000 feet MSL (the lower limit of Class A airspace). All airspace above FL 600 is Class E airspace. Uncontrolled airspace or Class G airspace is the portion of the airspace that has not been designated as Class A, B, C, D, or E.
What is FL600?
Basically FL600 means a pressure altitude of 60,000 feet. Above FL180/18000′ you change your altimeter to 29.92″. This is because the “Transition Altitude” in North Amercia is 18,000′ MSL. Flight level is divided into 100′ increments but always end in a 0 or 5.
Which type of service is provided in Class F airspace?
air traffic advisory service
Class F. IFR and VFR flights are permitted, all participating IFR flights receive an air traffic advisory service and all flights receive flight information service if requested.
What class airspace is uncontrolled?
Class G airspace
Uncontrolled airspace or Class G airspace is the portion of the airspace that has not been designated as Class A, B, C, D, or E. It is therefore designated uncontrolled airspace. Class G airspace extends from the surface to the base of the overlying Class E airspace.
What airspace is above 60000?
Airspace at any altitude over FL600 (60,000 MSL) (the ceiling of Class A airspace) is designated Class E airspace. The U.S. does not use ICAO Class F.
