The FAA issued a new Safety Alert for Operators (SAFO 06014) that seeks to clarify the conditions under which pilots can take off with frost adhering to airframes.

Business aircraft pilots taxiing into Toronto Pearson’s de-icing area this winter will see–since they’re hard to miss–two large truck-mounted de-icing units cleaning down 747s, A340s and other big iron. They’re Danish built Elephant Beta-15 rigs, with telescopic booms that can reach 75 feet, high enough to spray the top of the fin of an A380.
