A typical de-icing program includes which elements and when is it activated?

• A. Procedures for aircraft de-icing fluids, equipment, and times; activated in icing conditions to ensure safe departure.
• B. Only the use of anti-icing fluids.
• C. Training for ground crew on gloves and boots.
• D. Scheduling de-icing outside icing conditions.

Answer: (A)

A de-icing program is about planning and executing the removal of ice from the aircraft on the ground, using fluids and the right equipment in a coordinated way, with timing that ensures the removal is effective before departure. The key elements are clear procedures for applying de-icing fluids, the equipment used to apply them, and the timing aspects that tell you how long the fluids remain effective (holdover time) and when re-application is needed. This program is activated whenever icing conditions exist or are forecast, so the aircraft isn’t allowed to depart with ice on its surfaces. In practice, crews apply the fluids at the gate or ramp, confirm that all critical surfaces are clear, and monitor holdover times to decide if another application is required before taxi and takeoff. The other choices miss important parts or the correct activation timing: focusing only on anti-icing fluids, or mentioning unrelated training, or suggesting de-icing only when icing conditions are not present.
