A final inspection shall be performed prior to takeoff to ensure
effectiveness of the de-icing procedure. The inspection should be
conducted within 5 minutes of takeoff and may be conducted from inside
the airplane. If a visual inspection is not sufficient to determine whether
ice is adhering, perform a tactile check. Indications of loss of
effectiveness of de-icing/anti-icing fluid or contamination on airplane
surfaces include:
• Progressive surface freezing or snow accumulation.
• Random snow accumulation.
• Dulling of surface reflectivity (loss of gloss) caused by the
gradual deterioration of the de-icing/anti-icing fluid to slush.
If operating in ground icing conditions, a visual and tactile check of the
wing leading edge and upper surfaces must be performed as defined in
ICING LIMITATIONS (Section 2 – Limitations) of the Airplane Flight
Manual.
