1.303 IFR-IFR loss of separation (IFR-IFR LOS)

DESCRIPTION:

​Number of loss of separations between IFR flights.

STRATEGIC OBJECTIVE:

Aviation Safety

INDICATOR TYPE:

Outcome-related (Reactive or Lagging)

RATIONALE:

​A primary responsibility of an ANSP is to provide separation between IFR aircraft. As such, IFR-IFR losses of separation (IFR-IFR LOS) are one of the most critical safety issues under analysis on a global scale.

LIMITATIONS:

​Reporting methods (automatic or manual) and the way they are utilized are different across ANSPs.
Attribution of IFR-IFR LOS to ATM Ground versus ATM Airborne is not consistent.

CALCULATION METHOD/FORMULA:

​See attached indicator form (reference) below.
