Tribhuvan International Airport Runway Closed After Heavy Hail
Why It MattersA single weather-driven runway closure at a single-runway airport halts all arrivals and departures at once, so surface conditions rather than airspace capacity set the pace of recovery.
What happened
The runway at Tribhuvan International Airport in Kathmandu was closed after heavy rain accompanied by hail. The airport authority said significant amounts of hail began accumulating on the runway and taxiway areas from 2 pm.
The accumulated hail made the runway slippery, and both flight departures and arrivals were disrupted. Airport officials said operations were suspended while crews work to clear the ice from the runway.
Industry impact & what to watch
Hail on a runway is a different problem from rain alone: ice and slush reduce braking friction, and an airport generally cannot reopen until the surface has been cleared and judged safe for landing and takeoff. That makes the length of the suspension a function of how quickly ground crews can remove the accumulation, not of how quickly the weather passes.
For business-aviation operators with movements planned into or out of Kathmandu, a closure of this kind tends to push schedules around in both directions, since suspended arrivals and departures stack up behind each other once the surface is cleared. The practical thing to follow is the airport authority's announcement that clearing is complete and operations have resumed.
