VFR-on-Top Restrictions:
VFR-on-top is not permitted in certain airspace areas, such as Class A airspace, certain restricted areas, etc. Consequently, IFR flights operating VFR-on-top will avoid such airspace.
If unable to maintain VFR, an IFR clearance must be requred.
Class C. IFR and VFR flights are permitted, all flights are provided with air traffic control service and IFR flights are separated from other IFR flights and from VFR flights. VFR flights are separated from IFR flights and receive traffic information in respect of other VFR flights.
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.
It is that portion of the airspace that has not been designated as Control Area, Control Zone, Terminal Control Area or Transition Area. According to the airspace classes set by the International Civil Aviation Organization (ICAO), the uncontrolled classes of airspace are class F and G.
Class D. IFR and VFR flights are permitted and all flights are provided with air traffic control service, IFR flights are separated from other IFR flights and receive traffic information in respect of VFR flights, VFR flights receive traffic information in respect of all other flights.
Class B, C, D, E, and G airspace all have VFR weather minimums, but Class A is different. Since VFR travel, including SVFR, is not allowed in Class A airspace, there are no weather minimums to be aware of. All Class A flights are flown under ATC control and using instruments.
First, we must have clear sky or a scattered layer to climb through for VFR over-the-top. This is easily ascertained. Second, we must be sure that the broken or overcast layer does not rise beyond the capability of the airplane or the legal limit for flight without supplemental oxygen.
Can we fly over it? Technically yes, BUT it's still a very bad idea because a motor out would force you to descend through the Class C airspace. We CAN'T fly here without special permission from ATC. Permission should be obtained in advance by telephone (some controllers will accept a radio call).
Class C airspace is designed to establish and maintain safe separation of mixed general aviation and airline traffic. It is usually upside-down wedding cake shaped and depicted on charts with two bold magenta rings along with numbers indicating the airspace floor and ceiling within each ring.
For flights near airports in uncontrolled airspace that remain under 400' above the ground, prior authorization is not required. When flying in these areas, remote pilots and recreational flyers must be aware of and avoid traffic patterns and takeoff and landing areas.
Restricted airspace is an area of airspace typically used by the military in which the local controlling authorities have determined that air traffic must be restricted or prohibited for safety or security concerns.
