Takeoff from Copenhagen Kastrup (EKCH) airport in severe snow conditions.
I like how the pilot powered up the engine and held the brakes on.
They shot off like a bullet.
Operating commercial aircraft like the Boeing 737 in severe snow conditions demands a meticulous approach to ensure the safety of passengers and crew. While snow can present significant challenges, modern aviation has developed rigorous procedures and technologies to handle these conditions effectively.
Preparation is Key
- Aircraft Deicing: Before departure, the Boeing 737 undergoes deicing procedures to remove accumulated snow and ice from critical surfaces, including the wings, tail, and engine inlets. Deicing fluid, heated to an appropriate temperature, is sprayed to prevent the buildup of ice during takeoff.
- Runway Clearing: Airports equipped to handle snow conditions have specialized equipment for clearing runways, taxiways, and aprons. Snowplows, sweepers, and deicing trucks work to keep the runway surface as clear as possible.
- Weather Monitoring: Flight crews receive real-time weather updates and forecasts, allowing them to anticipate changing conditions and adjust their procedures accordingly.
Engine Start-Up
- Engine Heaters: Engines are equipped with heaters to ensure they start smoothly in cold conditions. Preheating the engines helps prevent issues like ice buildup in the engine core.
- Anti-Icing Systems: The Boeing 737 features anti-icing systems to protect critical components from ice accumulation during the takeoff roll.
Taxiing and Takeoff
- Taxiing on Cleared Paths: Pilots strictly adhere to cleared taxi paths to avoid deep snow accumulation that could affect aircraft control.
- Performance Calculations: Flight crews calculate takeoff performance considering factors like runway length, aircraft weight, engine thrust, and weather conditions. These calculations ensure a safe and successful takeoff.
- Deicing on Hold: In some cases, aircraft might be deiced just before entering the runway, ensuring that critical surfaces remain free of snow and ice during the takeoff roll.
