Yes, planes can fly in snow, but cold weather and snow challenge the aviation industry. These challenges include overdependence on de-icing equipment, sudden drop in aircraft performance due to fog and low visibility, and frequent flight delays due to snow-laden runways.
How Snow Affects Planes’ Flying Operations in Snowy Conditions?
Aircraft are designed to perform in extreme weather conditions, especially at higher altitudes 30,000 feet above sea level. The temperature can drop as low as -70 degrees Fahrenheit at such cruising altitude. These planes are built to fly in these cool temperatures. But, snow can impact flights in other ways, that are unavoidable:
- Reduced Visibility: Heavy snowfall can reduce visibility, making takeoff, landing, and navigation extremely difficult for pilots.
- Runway Conditions: Snow accumulation on runways can affect traction. It may increase the risk of skidding during takeoff and landing.
- Ice Accumulation: Ice can form on the aircraft’s wings. It may affect the aircraft’s thermodynamics and performance.
- Cold-Weather Impact on Aircraft Components: Snowy weather may lead to potential mechanical issues such as metal contraction, freezing fluids, and brittle components.
How Planes Fly in Snow and the Essential Pre-Flight Preparations for Safe Operations
Even with the right measures to safeguard your plane while it’s still on the ground, some preparations need to be executed before takeoff in the snow. These safety processes include:
De-Icing:
The most common pre-flight safety measure before takeoff is de-icing. Ice on wings is not good from the balance point of view between aerothermodynamics and weight, thrust, and drag during the flight.
Even a single layer of ice sheet can disrupt a balance, affecting the performance of the aircraft. It may lead to decreased fuel efficiency and slower takeoff speeds.
Airlines use glycol-based de-icing fluids that remove ice from the aircraft’s surface. This safety process can be time-consuming, but it is essential for passengers’ safety. Depending on the size of the aircraft and the magnitude of ice buildup, de-icing may take hours before the flight commences.
In addition, there are smaller aircraft which lack the in-built de-icing equipment. During these extreme conditions, it may restrict their operations.
Runway Maintenance:
Heavy snowfall can make it difficult for crews to keep runways clear. It is similar to how snow building up on our roads and highways can hinder regular traffic.
The Airport authorities execute robust snow management during cold weather, which includes frequent runway clearing. However, severe weather conditions can still make it challenging to maintain clear paths.
If runways have accumulated ice, the aircraft may skid or slip, which makes it dangerous to sustain pre-flight and post-flight operations. Just like vehicles’ tires on the road, aircraft wheels require proper grip with the pavement to ensure safe movement during takeoff and landing.
Can Small Aircraft Fly in Snow?
Large commercial jets have in-built de-icing systems that make them immune to harsh and cold weather conditions. However, smaller planes lack this equipment, making them more vulnerable to freezing temperatures, thus restricting their mobility. Pilots of small jets are required to implement the following safety measures:
- Frequent cheeks for ice and snow accumulation
- Avoid flights during heavy snowstorms or hailstorms
- Flying at lower altitudes, which are much warmer to prevent ice formation.
Bigger aircraft are designed to fly in snowy weather, but pilots and ground crews need to take extra safety measures. The harsh cold weather may reduce visibility, make runway skids, and impact flight operations. But certain pre-flight preparations in place may mitigate these risks.
These measures include de-icing and frequent clearing of runways. While larger aircraft like Airbus and Boeing are well-equipped for winter weather, small aircraft may lack in-built systems for de-icing. This makes them more vulnerable to ice accumulation and requires extra precautions before and during flight.
