Norway enhances safety between military and civil aviation through EUROAT

Norway has become the 19th state to implement EUROAT, EUROCONTROL's Specifications for harmonised Rules for Operational Air Traffic (OAT) under Instrument Flight Rules (IFR) in ECAC’s controlled airspace.

The EUROAT specification is an important safety facilitator for military and civil flights.

EUROAT:

  • provides a regulatory framework for operational air traffic under instrument flight rules (OAT-IFR) in controlled European airspace;
  • improves the interface between OAT and General Air Traffic (GAT);
  • minimises the impact of GAT restrictions on military operational procedures and aerial tactics.

For military pilots, EUROAT is a comprehensive document containing OAT flight rules when operating under OAT in the airspace of implementing States.

For civil air traffic controllers (ATCOs), it contains essential information on how the military fly under OAT when not following GAT rules.

There are three principles:

  1. where possible, EUROAT reuses ICAO or Standard European Rules of the Air (SERA) rules, procedures and definitions as specified for GAT flights;
  2. EUROAT details the rules required for OAT, when they are in addition to or where they deviate from ICAO/SERA provisions;
  3. when the operational requirements of a flight are incompatible with these, an Airspace Reservation (ARES), of the right type and dimension should be filed, or other methods used that are considered safe and which have been approved by the appropriate national authority.

EUROAT is an important cornerstone of EUROCONTROL’s civil-military cooperation. Eight more states have confirmed their intention of signing up for it before the end of 2020.
