1 ATS Airspace Classification

Estonia follows requirements established by the European Commission Implementing Regulation (EU) No 923/2012. Estonia uses airspace classes C, D and G.

2 ATS Airspace Description

Classification and applicable airspace classes of Estonian ATS airspace are described in more detail in the following tables:

ENR 2.1 FIR/CTA and TMA
ENR 3 ATS ROUTES
AD 2.17 ATS AIRSPACE

ATS airspace classes are described sections ENR 2.1 and AD 2.17.

Class	Type of flight	Separation provided	Service provided	Speed limitation ¹	Radio communication capability requirement	Continuous two-way air-ground voice communication required	Subject to an ATC clearance

F	VFR	NIL	Flight information service if requested	250 kt IAS below 3 050 m (10 000 ft) AMSL	No ²	No ²	No
G	IFR	NIL	Flight information service if requested	250 kt IAS below 3 050 m (10 000 ft) AMSL	Yes ²	No ²	No
G	VFR	NIL	Flight information service if requested	250 kt IAS below 3 050 m (10 000 ft) AMSL	No ²	No ²	No

¹ When the level of the transition altitude is lower than 3 050 m (10 000 ft) AMSL, FL 100 should be used in lieu of 10 000 ft. Competent authority may also exempt aircraft types, which for technical or safety reasons, cannot maintain this speed.

² Pilots shall maintain continuous air-ground voice communication watch and establish two-way communication, as necessary, on the appropriate communication channel in RMZ.

³ Air-ground voice communication is mandatory for flights participating in the advisory service. Pilots shall maintain continuous air-ground voice communication watch and establish two-way communication, as necessary, on the appropriate communication channel in RMZ.
