How many categories of runway incursions are there?

There are four categories of runway incursions, which help aviation professionals categorize incidents based on severity and circumstances. This classification system aids in understanding the nature of each incursion and developing strategies for preventing future occurrences.

The categories address different types of violations such as unauthorized aircraft, vehicle movements on the runway, and other actions that could pose a risk for collisions. By having four distinct categories, personnel can standardize their response protocols and enhance safety measures, leading to a reduction in the number of runway incursions overall. This framework supports pilot and air traffic controller training as well as incident analysis, which is crucial for maintaining operational safety at airports.
