ENR 1.4 ATS AIRSPACE CLASSIFICATION AND DESCRIPTION

1 ATS AIRSPACE CLASSIFICATION

ATS airspaces are classified and designated in alphabetical order in accordance with the following:

Class A: Only IFR flights are permitted, all flights are subject to air traffic control service which provides separation between them.

Class B: IFR and VFR flights are permitted; all flights are subject to air traffic control service which provides separation between them.

Class C: IFR and VFR flights are permitted; all flights are subject to air traffic control service; IFR flights are separated between them and from VFR flights; VFR flights are separated from IFR flights only and receive traffic information on other VFR flights and traffic avoidance advice on request.

Classe D: IFR and VFR flights are permitted and all flights are subject to air traffic control service, IFR flights are separated between them and receive traffic information on VFR flights (and traffic avoidance advice on request). VFR flights receive only traffic information on all other flights
(and traffic avoidance advice on request).

Classe E: IFR and VFR flights are permitted; IFR flights are subject to air traffic control service and are separated between them; all flights receive traffic information as far as is practicable; VFR flights may fly within this airspace without previous authorization and notification.

Classe F: IFR and VFR flights are permitted; only IFR flights receive air traffic advisory service; all flights receive flight information service on request.

Classe G: IFR and VFR flights are permitted and only flight information service is provided, on request.

2 ATS AIRSPACE DESCRIPTION

Generally speaking, airspaces and their respective limits within FIR under brazilian jurisdiction, will be classified as follows:

Class G for all FIR, GND/UNL or GND-MSL/UNL.

Class A for all CTA / TMA between FL145/FL245.

Class A for all UTA.

Class A for all upper and lower airways, above FL145.

Class D for all lower airways at and below FL 145.

Class F for all advisory routes.

Class G for all information routes.

The other parts of airspaces and their limits were classified as shown in the Area and Enroute Charts and in section ENR 2.
