- all other accidents combined
- the most significant hazard
In a study conducted by the Federal Aviation Administration, it was projected that accidents and collision due to runway incursions could cause more US domestic jet deaths over the next two decades than all other accidents combined. The US National Transportation Safety Board (NSTB) believes that runway incursions are one of the most significant hazards in aviation today.
Runway incursion as defined by the International Civil Aviation Organization (ICAO) means “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.” 
- lesser traffic density
- raise awareness
- casual factors
In New Zealand, in spite of lesser traffic density and decreasing number of runway incursions from a peak of around 90 in 1994 to less than 40 in 2008, the Civil Aviation Authority highlights the timely and urgent need to raise awareness on runway incursion and the causal factors which lead to potentially disastrous incidents.
- increase the likelihood
- complex layouts
- inadequate signage
- taxi routes
According to Transport Canada, the factors that may be a causal factor to the increase in runway incursion are:
– the increase in traffic volume which would increase the likelihood of runway incursion
– complex aerodrome layouts from improvement projects which together with inadequate signage’s, markings, aerodrome design standards and lack of standard taxi routes.
