Book Description
A detailed study is proposed for understanding the use of aircraft deicing and antiicing fluids (ADAF) and optimal use of these fluids in airport operations. A detailed literature review of past and current technologies is conducted and possible opportunities to improve the use of ADAF and relevant recommendations are derived. Mathematical optimization models (e.g. MINLP with binary variables) based on a variety of objectives, which deal with exhaustive sets of system constraints are formulated, developed and applied to case studies. One real-life case study area which routinely carries out aircraft deicing is used for testing the mathematical optimization formulations for optimal use of fluids under budgetary and environmental compliance constraints. Based on the recommendations from one of the best optimization model formulations it is hoped that it will be used for a real-time implementation. Results from these formulations show the models to be robust and applicable.

Book Description
"A new formulation fluid is proposed for use as the reference fluid for aerodynamic testing and qualification of commercial aircraft deicing and anti-icing fluids. The new formulation fluid is to replace the currently used reference fluid, MIL-A-8243D, which allows for large variation in its composition. The MIL-A-8243D fluid, manufactured up to 2005, is no longer commercially available because its chief user, the United States Military, now uses qualified commercial Society of Automotive Engineers deicing and anti-icing fluids. The new formulation fluid, a mixture of 68% propylene, 20% tripropylene glycol, and 12% demineralized water, is chemically compatible with current glycol-based fluids. Furthermore, it can be produced more simply and accurately than the more complex military (MIL) formulation it replaces. Having the same viscosity as MIL-A-8243D, the new formulation reference has been found to be essentially aerodynamically indistinguishable from the MIL fluid in validation test runs in which both fluids were tested with a candidate fluid for high-speed ramp aerodynamic standard qualification. The measurements and validation testing accomplished in the present study support the adoption of the new fluid for use as the reference fluid for the high-speed ramp standard aerodynamic qualification test in place of the current MIL fluid."--Page [ii].

This document shall be used in conjunction with: -AS6286, Training and Qualification Program for Deicing/Anti-icing of Aircraft on the Ground -AS6286/1, Processes Including Methods -AS6286/2, Equipment -AS6286/3, Fluids -AS6286/4, Weather -AS6286/5, Health, Safety and First Aid This document outlines permissible fluid application areas for Deicing and Anti-icing fluids, no-spray/no-direct fluid application areas, and other cautionary areas/items by aircraft type.The diagrams and cautions are generic representations of the aircraft types specified, and apply to all series/variants unless indicated otherwise.In conjunction with the main document AS6286 and other related slash sheets it will provide training and qualification standards to set up a proper training and qualification program to deice and anti-ice aircraft on the ground information to support this training program is provided to make the material a better tool for the preparation and execution of the training and qualification. It is intended to provide a common basis for de-icing/anti-icing training and qualification for de-icing providers and airlines. This material was compiled using various international documents with support from SAE documents and individually contributed editorial comments. Its purpose is to serve as a "Globalized Deicing Training Manual".The document is intended to promote and develop safe practices, effective procedures and improved technology related to training of aircraft ground operations in winter conditions to ensure the highest possible levels of safety for passengers, flight crew and ground personnel.It shall ensure continued compliance with all relevant standards and regulatory requirements, and shall ensure that it continues to reflect current industry best practice.It can be utilized to develop a set of commonly agreed training practices and procedures for the deicing/anti- icing of aircraft on the ground reflecting current industry best practice. It shall ensure continued compliance with all relevant standards and regulatory requirements, and shall ensure that it continues to reflect current industry best practice.
