What is De-icing
Winter is here, and as temperatures begin to drop below zero, it’s the perfect time to discuss de-icing—what it is, how it works, why it’s essential, and the costs involved.
De-icing is the process of removing ice, snow, or frost that accumulates on an aircraft’s critical surfaces, such as the wings, tail, and control surfaces. Ice on these areas can disrupt airflow and negatively affect the aircraft’s aerodynamics, potentially leading to reduced lift, increased drag, and dangerous flying conditions. Aviation history includes numerous serious incidents caused by inadequate or neglected de-icing procedures.
When is de-icing used?
De-icing is performed:
- Before takeoff: When ice, frost, or snow has accumulated on the aircraft while on the ground. Usually, de-icing will be required when temperature drop below 2 or 3 degrees, especially for morning departures after a cold night.
- During flight: In extreme cases, de-icing systems onboard the aircraft are used to prevent ice buildup on essential parts like engines and wings.
Why is it important?
- Maintains Aerodynamics: Ice changes the shape of the aircraft’s surfaces, disrupting airflow and reducing lift.
- Prevents Malfunctions: Ice on control surfaces can impair the pilot’s ability to maneuver the aircraft.
- Safety Compliance: Aviation regulations require that aircraft are free of ice before takeoff to ensure safe operations.
- Engine Protection: Ice can block inlets or disrupt airflow into engines, leading to performance issues or damage.
How is it done?
- Ground De-icing: Specialized vehicles spray heated de-icing fluids (a mixture of water and glycol) onto the aircraft.
- In-Flight De-Icing: Aircraft are often equipped with anti-icing or de-icing systems like heated surfaces, pneumatic boots, or weeping wings that release fluid to prevent ice formation.
De-icing is a critical part of aviation safety, especially in winter or cold weather conditions.
How much does it cost and can it be avoided?
De-icing prices can be expensive. They vary from one airport to another and from one aircraft type to another. For example, for a light jet in Geneva, it will probably cost you 1’500€. For a large aircraft it can cost up to 7’000 or 8’000 €.
De-icing is generally unpredictable and, as a result, is usually excluded from JetFlo’s offers. However, there are a few strategies to help minimize or avoid de-icing costs
- Spend the night in a hangar: If we know that your departure is scheduled for the next day early in the morning, we can ask that the aircraft would be put in hangar (if available) to avoid de-icing. The extra cost for one night in a hangar is always less than de-icing cost.
- De-icing insurance: Some operators have developped a De-icing insurance allowing you to avoid the element of surprise and the inconvenience of receiving an invoice after the flight.
If you have a flight scheduled in the coming days, your JetFlo representative will discuss all de-icing related matters with you
