SAE AS6285B

This document establishes the minimum requirements for ground based aircraft deicing/anti-icing methods and procedures to ensure the safe operation of aircraft during icing conditions on the ground. This document does not specify the requirements for particular aircraft models. The application of the procedures specified in this document are intended to effectively remove and/or prevent the accumulation of frost, snow, slush, or ice contamination which can seriously affect the aerodynamic performance and/or the controllability of an aircraft. The principal method of treatment employed is the use of fluids qualified to AMS1424 (Type I fluid) and AMS1428 (Type II, III, and IV fluids). All guidelines referred to herein are applicable only in conjunction with the applicable documents. Due to aerodynamic and other concerns, the application of deicing/anti-icing fluids shall be carried out in compliance with engine and aircraft manufacturer's recommendations. This Revision B includes additional requirements for checks on fluid and documents during deliveries of aircraft de/anti-icing fluids in 4.3.1. These changes reduce the risk of accepting fluid that is out of specification. Section 8.7.20 has been added as additional guidance for aircraft with folding wings. This Revision B becomes effective as of May 1, 2019.
