Many airports throughout the world have joint commercial-military operations. Runways at these airports often are equipped with arresting gear systems for tactical military aircraft to use for landing. These systems pose a potential damage and safety hazard to commercial airplanes that use the same runways. Airports and airlines can take steps to help ensure safe commercial operations under such circumstances. Measures include writing airport procedures specifically for commercial airplane operations, modifying existing arresting systems, reducing declared landing and takeoff distances, and increasing inspections of airplanes with nosegear spray and gravel deflectors.
