Highest runway safety risks

Analysis of the major runway safety issues shows that runway excursions and especially runway veer offs are related to the highest costs. These account for $ 2 Billion dollar per year (figures corrected for local purchasing power).  

Runway event risk trends: Hub’s Down

Runway Risk decreases at Hub aerodromes; increasing at Regional and Municipal airports.

Distribution of costs per runway OCCURRENCE CATEGORY

40% of the costs are due to disabled aircraft on the runway. These are often related to gear malfunctions. Others include on runway evacuations or crashes on the runway ( e.g. EK 521 at Dubai 3 aug 2016). Runway excursions account for 61% of the costs, under-runs for 7%, whilst incursions only for 2%.

Distribution of Costs per runwy excursion

Within runway excursions are veer offs the most costly events. Almost twice the costs associated with runway overruns. Runway underruns seems to occur mainly with light aircraft, either returning due to technical failures or fuel related problems.

General aviation has the largest number of runway safety events (Blue), whilst the associated costs re the highest with Commercial Air Traffic (Red). The military have the highest average costs per event.
