ATS airspace classification

ENR 1.4 ATS airspace classification

1.4.1 Airspace classes used in the EMIRATES FIR are illustrated below.

Note: The lower level of airways vary and is not necessarily the 4500 FT or 2500 FT as illustrated.

** When so prescribed by the General Civil Aviation Authority (ref. ENR 1.2)

lower flight visibilities to 1500 M may be permitted for flights operating:
1. at speeds that will give adequate opportunity to observe other traffic or any obstacles in time to avoid collision; or
2. in circumstances in which the probability of encounters with other traffic would normally be low, e.g. in areas of low traffic volume and for aerial work at low levels;
Helicopters may be permitted to operate in less than 1500 M flight visibility if manoeuvred at a speed that will give adequate opportunity to observe other traffic or any obstacles in time to avoid collision.

In all cases such flights shall be operated at or below 3000 FT AMSL, or 1000 FT above terrain whichever is higher, clear of cloud and in sight of the surface.
