Uitleg ICAO-ernstcategorieën bij een voorval

De International Civil Aviation Organisation classificeert voorvallen afhankelijk van de ernst in een vijftal categorieën.

Serious Incident

An incident involving circumstances indicating that an accident nearly occurred. Note: The difference between an accident and a serious incident lies only in the result.

Major Incident

An incident associated with the operation of an aircraft, in which safety of aircraft may have been compromised, having led to a near collision between aircraft, with ground or obstacles (i.e., safety margins not respected which is not the result of an ATC instruction).

Significant Incident

An incident involving circumstances indicating that an accident, a serious or major incident could have occurred, if the risk had not been managed within safety margins, or if another aircraft had been in the vicinity.

No safety effect

An incident which has no safety significance.

Not determined

Insufficient information was available to determine the risk involved or inconclusive or conflicting evidence precluded such determination.
