It might be helpful to state here that the source of the classificaton of AIRPROX risk is ICAO. It might be additionally helpful to remind readers that the classification is supposed to be assigned only based on actual' risk - no account is supposed to be taken of potential risk.This has often been misunderstood in the past.
It might also be useful to clarify that the process of independent AIRPROX review and classification is subsidiary to State Investigations of Serious Incidents involving aircraft-to-aircraft proximity falling under ICAO Annex 13 procedures which may, in some jurisdictions, be undertaken by means of an entirely different procedure to 'routine' AIRPROX investigations.
Finally, it might also be worth noting that the definition of an AIRPROX was decided prior to the availability of both ACAS-equipped aircraft and widespread availability of ATC Radar Recordings.--Ed.Pooley 01:20, 11 January 2008 (CET)
