This document establishes the minimum training and qualification requirements for ground-based aircraft deicing/anti-icing methods and procedures. 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 manufacturers’ recommendations. The scope of training should be adjusted according to local demands. There are a wide variety of winter seasons and differences of the involvement between deicing operators, and therefore the level and length of training should be adjusted accordingly. However, the minimum level of training shall be covered in all cases. As a rule of thumb, the amount of time spent in practical training should equal or exceed the amount of time spent in classroom training.
This document provides the industry standards and guidance for the training and qualifying of staff, plus the expected contents of this training for effective deicing and anti-icing of aircraft on the ground. It forms one part of three related SAE Aerospace Standards (AS) and should be read in conjunction with AS6285 and AS6332. Collectively, AS6285, AS6286, and AS6332 are known to the international community as “the Globalized Aircraft Deicing Standards.”
Exposure to weather conditions conducive to ice formation can cause the accumulation of frost, snow, slush, and ice on aircraft surfaces and components. These contaminants can adversely affect aircraft performance and controllability. In addition, they can adversely affect the operation of mechanical devices such as control surfaces, sensors, flaps, and landing gear. If frozen deposits are present other than those accounted for in the aircraft certification process, then the performance and safety of the aircraft will be compromised.
Regulations governing aircraft operations in ground icing conditions shall be followed. The International Civil Aviation Organization ICAO “Annex 6, Part I” and “Annex 14, Vol. I” mandate specific rules for the safe operation of aircraft during ground icing conditions, and all member states subsequently are required to have regulations in place to ensure conformance with these. Paraphrased, these rules specify that no one may dispatch or take off an aircraft with frozen deposits on components of the aircraft that are critical to safe flight. A critical surface or component is one which could adversely affect the mechanical or aerodynamic function of an aircraft. The intent of these rules is to ensure that no one attempts to dispatch or operate an aircraft with frozen deposits adhering to any aircraft component critical to safe flight. This is known as the “Clean Aircraft Concept.”
This document specifies the standards for training and qualifying staff, plus the expected contents of their training. It provides guidance for the setting up of a proper training and qualification program for the deicing and anti-icing of aircraft on the ground. Although references are made to the other two globalized standards, some background information to support a training program is provided to make the material a better tool for the preparation and execution of the training and qualification process. Standard teaching plans and a practical assessment method are included. This material was compiled using various international documents, with support from SAE standards and individually contributed editorial comments. Its purpose is to serve as a “Globalized Deicing Training Manual.” In addition, each organization involved in aircraft ground deicing and anti-icing is responsible for complying with local regulations and requirements imposed by manufacturers of aircraft, equipment, and fluids, in addition to regulatory and environmental authorities.
This Revision B represents a completion of the work performed in Revision A. Some work was undefined or under discussion so for the sake of clarity, Revision A was completed with some items outstanding with the intention of following up quickly with Revision B. All changes are marked with a black line on the left of the page.
Changes made are:
1
Inclusion of outstanding comments/corrections from Revision A.
2
“Inspection” is replaced with “Check.”
3
New diagrams for new aircraft.
