Bravo and F airports do not exist here in France. Some airspaces even have an extra speed restriction (below 140 knots under 3000 feet for VFR trafic of visibility is below 5000m).
Here how it works in Europe:
A: IFR ONLY in most airspaces, VFR if cleared by the ATC. lateral and vertical separation between IFR planes. ATC available and communicating with the ATC is mandatory, clearances are also mandatory. 250 below 10 000 feet.
B: IFR mostly, all kind of VFR allowed. Lateral and vertical separation between IFR/ IFR, IFR/ VFR and VFR/VFR planes. ATC available and communicating with the ATC is mandatory, clearances are also mandatory. 250 below 10 000 feet.
C: B: IFR and all kind of VFR allowed. Lateral and vertical separation between IFR planes and between VFR/ IFR. ATC available for IFR and VFR planes, a FIS* is also available. Communicating with the ATC is mandatory, clearances are also mandatory. 250 below 10 000 feet.
D: IFR and VFR/ SVFR allowed. Lateral and vertical separation between IFR planes and between SVFR/ IFR. ATC available for IFR and SVFR planes, a FIS* is also available. Communicating with the ATC is mandatory, clearances are also mandatory. 250 below 10 000 feet.
E: IFR/ VFR. Lateral and vertical separation between IFR planes only. ATC available for IFR and SVFR planes, a FIS* may be available. Communicating with the ATC is mandatory (IFR only), clearances are also mandatory (IFR only). 250 below 10 000 feet.
F: IFR/ VFR. Lateral and vertical separation between IFR planes may be provided. No ATC service available. A LAA is available for IFR planes, a FIS* is available for VFR planes. Communicating with the LAA is mandatory (IFR only). 250 below 10 000 feet.
G: IFR/ VFR. Lateral and vertical separation will not be provided. No ATC service available. A FIS* is available for IFR/ VFR planes. Communicating with the FIS is mandatory (IFR only). 250 below 10 000 feet.
- The FIS may suggest a flight path to avoid an obstacle if asked to.
I hope this is clear enough; sorry for writing such a long text but it couldn’t be shorter :)
