Runway safety remains one of the most serious threats to aviation safety. Because of this, ICAO and CAA see it as a high priority.
Runway safety includes runway incursions, runway excursions, and runway confusion. Improving runway safety requires collaboration from all stakeholders including ATC, airports, CAA, aircraft operators, and everybody who operates around a runway.
The ICAO definition of a runway incursion is “Any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle or person on the protected area of a surface designated for the landing and take off of aircraft”. Approximately 5-10 occur in New Zealand every month, and have the potential to result in fatal collisions.
Incident reports show that runway incursions do not occur randomly around an aerodrome, but are often clustered at hotspots. Hotspot diagrams are an ICAO-endorsed and internationally recognised method of providing information about aerodrome locations with an increased risk for incursions. Significant hotspots may be included in the aerodrome diagrams in the AIP.
A runway excursion occurs when an aircraft veers off, or overruns, the runway surface during either take-off or landing. This can be caused by factors including runway contamination, adverse weather conditions, mechanical failure, pilot error, and unstable approaches. While New Zealand has had no fatal runway excursion incidents, the high number of international accidents demands a proactive approach to manage the risk.
Runway confusion occurs when pilots enter, take off, or land on the wrong runway. This is a particular problem at aerodromes with parallel runway systems. Runway confusion can also occur when a taxiway, usually parallel, is mistaken for a runway - this is more often a problem at night.
In addition to thoroughly planning your aerodrome operation and maintaining situational awareness, to avoid runway confusion:
Airside drivers play an important role in runway safety at all aerodromes. There are instances of vehicles being involved in serious runway incursions, so drivers need to ensure they're prepared to operate safely.

Local runway safety teams (LRST) are an important component of the global runway safety program. The LRST consists of local representatives addressing local runway safety issues. At some airports the LRST is embedded in another aerodrome meeting, such as the Aerodrome Users Group or Airport Safety Committee.
The LRST should include representatives from the aerodrome operators, air traffic services, commercial air operators, representatives of flight crew familiar with the aerodrome, and members from the general aviation community (if applicable). It may also include the regulatory authority (as an observer), military operator (if applicable, based on joint use of the aerodrome), support services (de-icing, catering, ground handling, etc.), emergency response service providers, and subject matter experts such as meteorologists and ornithologists. Consideration may also be given to periodically inviting members of other LRSTs to promote coordination, learning and the sharing of information.
