飞机除冰对于冬季安全飞行至关重要，它使用基于乙二醇的液体来防止冰积聚，从而减少升力。 Airplane deicing, crucial for safe winter flights, uses glycol-based fluids to prevent ice buildup that can reduce lift.

飞机除冰对于冬季飞行至关重要，因为冰可以使升力减少多达 30%，影响机动性并提高失速速度。 Airplane deicing is vital for winter flights as ice can slash lift by up to 30%, affecting maneuverability and increasing stall speed. 该工艺以两步法使用基于乙二醇的液体：用加热的 I 型流体除冰，然后用 II 型或 IV 型流体进行防冰，以防止进一步结冰。 The process uses glycol-based fluids in a two-step method: deicing with heated Type I fluid followed by anti-icing with Type II or IV fluids to prevent further ice. 丙二醇的毒性比乙二醇小，目前很常用。 Propylene glycol, less toxic than ethylene glycol, is commonly used today. 环保工作包括回收和处理液体，以最大限度地减少对生态的影响。 Environmental efforts include recycling and treating the fluids to minimize ecological impact.
