Severe Air Traffic System Hazard (Operational Error)
A severe air traffic system hazard is an occurrence attributable to an element of the air
traffic system, to include aircraft/vehicle operators and air traffic controllers which:
Less than the applicable separation minima results between two or more
airborne aircraft, or less than the applicable separation minima results between
an aircraft and terrain or obstacles (e.g., operations below Minimum Vectoring
Altitude (MVA); aircraft/equipment/personnel on runways), as required by FAAO
JO 7110.65 or other appropriate directive; or
An aircraft lands or departs on a runway closed to aircraft operations after
receiving air traffic authorization; or
An aircraft lands or departs on a runway closed to aircraft operations, at an
uncontrolled airport and it was determined that a Notice to Airmen (NOTAM)
regarding the runway closure was not issued to the pilot as required.
Routine Air Traffic System Hazard (Operational Deviation)
A routine air traffic system hazard is an occurrence attributable to an element of the air
traffic system in which applicable separation minima as required by FAAO JO 7110.65
or other appropriate directive was maintained, but:
Less than the applicable separation minima existed between an aircraft and
adjacent airspace without prior approval; or
An aircraft penetrated airspace that was delegated to another position of
operation or another facility without prior coordination and approval; or
An aircraft penetrated airspace that was delegated to another position of
operation or another facility at an altitude or route contrary to the altitude or route
requested and approved in direct coordination or as specified in a Letter of
Agreement (LOA), pre-coordination, or internal procedure; or
An aircraft is either positioned and/or routed contrary to that which was
coordinated individually or as specified in a LOA/directive between positions of
operation in either the same or a different facility; or
Aircraft, vehicle, equipment, or personnel encroached upon a landing area that
was delegated to another position of operation without prior coordination and
approval.
Reporting Air Traffic System Hazards
The reporting of air traffic system hazards is an element of the Naval Aviation Safety
Program. Reporting requirements and format are contained in OPNAVINST 3750.6. A
severe hazard report must be reported within 3 working days and a routine hazard
report must be submitted within 30 working days.
