TheEconomic Imperative for Touchless Runway Maintenance

Runway closures are among the most most lossive events an airport can face. A single hour of runway downtime at a major international hub can cost airlines andd airport operators hundreds of tygenands of dollars in delays, diversions, and lost revenue. Traditional convenance methods require closing runways for expestded period, often during night hours when traffic is lower but wheren convenance crewws must work under time presere and -thaneid conditions.
