| All airspace below TMA LJUBLJANA 1, TMA MARIBOR 2 and TMA PORTOROZ | GND | 1000 ft GND |
| All airspace below TMA LJUBLJANA 3 | GND | 5500 ft MSL |
Description of airspace classes
Class C Airspace
- IFR and VFR flights are permitted, all flights are provided with air traffic control service. 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.
- Entry clearance has to be obtained at least 5 min. prior to entering class C airspace.
- Below 10000 ft AMSL: max. 250 kt IAS except for military aircraft.
Class D Airspace
- 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.
- Entry clearance has to be obtained at least 5 min. prior to entering class D airspace.
- Below 10000 ft AMSL: max. 250 kt IAS except for military aircraft.
Class E Airspace
- IFR and VFR flights are permitted, IFR flights are subject to air traffic control service and are separated from other IFR flights.
- All flights receive traffic information as far as practicable.
- Neither radio communication nor ATC clearance is required. However, they are recommended.
- Below 10000 ft AMSL: max. 250 kt IAS except for military aircraft.
Class G Airspace (Uncontrolled)
- All flights are permitted and receive flight information service if requested.
- Air-ground communication and ATC clearance not required.
- Below 10000 ft AMSL: max. 250 kt IAS except for military aircraft.
Note:
Military jet flights are permitted within the whole FIR (also aircraft faster than 250 kt IAS). They often use class G airspace.
