Not an acceptable method for removing frost or ice from aircraft windows?

Visible frost or ice on aircraft windows must be removed using methods approved for the windshield to prevent damage and maintain safe visibility. Scraping with metal tools is not acceptable because it can gouge or scratch the glazing and coatings, potentially weakening the windshield or damaging the heating elements. Such damage can compromise structural integrity and safety while in operation. In contrast, approved de-icing fluids applied by qualified staff, the aircraft’s defrost/heating system, and, where permitted by procedures, windscreen wipers are designed to remove frost and ice without harming the windshield. Therefore, metal scraping is the wrong method.
