A.2 ECAC objectives
A.2.1 High-level objectives
The ECAC Strategy for the 1990s, signed by the Transport Ministers in Paris on the 24 April 1990, adopted six operational objectives :
1.
The air traffic services route network and airspace structure is to be optimised, supported by a widespread application of area navigation from 1993 onwards.
2.
Comprehensive radar coverage is to be applied throughout the area by 1995 at the latest.
3.
En-route radar separation of 5 NM is to be applied throughout high-density areas by 1995 at the latest. Elsewhere, en-route radar separation of 10 NM is to be applied by the same date.
4.
Air traffic control systems are to be progressively integrated, after being harmonised in high-density areas by 1995 at the latest, and elsewhere not later than 1998.
