When pretreating an aircraft without the flight crew present, what form must be completed?

When pretreating an aircraft without the flight crew present, it is essential to complete the Pilot notification of the Deicing/Anti-icing Form. This form serves to inform the flight crew that the aircraft has been treated with deicing or anti-icing fluid in their absence and ensures that all relevant details regarding the treatment process are communicated.

Proper documentation is crucial in aviation operations to maintain safety standards and compliance with regulations. By completing this form, the receiving flight crew is made aware of the conditions and status of the aircraft, thereby allowing them to make informed decisions during pre-flight preparations. This notification process is especially critical as it fosters communication between ground crews and flight crews, ensuring that safety measures are upheld and the aircraft is adequately prepared for flight.

In contrast, the other forms mentioned may be relevant to different aspects of aircraft maintenance or pre-flight checks but do not specifically address the need for communication of the deicing/anti-icing process in the absence of the flight crew.
