De-Icing and Departure Delays: A Step-by-Step Checklist
De-icing is a critical procedure to ensure aircraft safety during winter operations. Proper de-icing and anti-icing are essential to prevent ice accumulation on critical surfaces, which can affect aircraft performance and safety. This step-by-step checklist provides guidance on de-icing procedures and managing departure delays.
1. Assess Weather Conditions
-
Freezing Precipitation: If freezing precipitation is present, delay departure until conditions improve. (aircrafticing.grc.nasa.gov)
-
Active Frost: If active frost is present, determine if anti-icing is possible. (aircrafticing.grc.nasa.gov)
2. Perform De-Icing Procedures
-
One-Step De-Icing: Apply heated anti-icing fluid to remove existing ice and prevent new ice formation. (pilotinstitute.com)
-
Two-Step De-Icing: First, apply heated fluid to strip away ice; then, apply a separate overspray of anti-icing fluid to protect surfaces during ground operations. (pilotinstitute.com)
3. Communicate with Ground Crew
-
Fluid Application Details: Ensure the ground crew provides the flight crew with the type of fluid used, concentration, and application time. (faa.gov)
-
Post-Application Inspection: Confirm that the aircraft is free from contamination before departure. (aircrafticing.grc.nasa.gov)
4. Manage Departure Delays
-
Holdover Time (HOT): Be aware of the HOT, which is the time anti-icing fluid remains effective. (pilotinstitute.com)
-
Pre-Takeoff Check: Conduct a final inspection to ensure the aircraft is clean and free from ice or snow. (aircrafticing.grc.nasa.gov)
