Air carrier ground deicing/anti-icing problems

摘要

The Aviation Safety Reporting System (ASRS) Office shares the FAA's and the Industry's desire to increase aviation safety through improved airline ground deicing/anti-icing procedures. Through this interest ASRS has undertaken this research effort to learn more about the human factors involving air carrier ground deicing/anti-icing, including an examination of the effects of the new FAA regulations concerning deicing/anti-icing. In order for a report to be included in the study set, it must have: (1) involved air carrier operations, and (2) mentioned ground deicing/anti-icing activity, or made some other reference to frozen contamination not being removed from aircraft critical surfaces before takeoff. This study focused on the human factors associated with air carrier ground deicing/anti-icing. We sought to determine psychological and physical factors that affect a person's ability to properly detect ice, remove ice, and assure that the aircraft critical surfaces are free of ice before takeoff. Psychological factors evaluated included (but were not limited to) judgement and decision making, perceptual aspects, motivational, and attentional factors. Physical factors that we evaluated were (but were not limited to) difficulties trying to inspect and/or remove ice from wings that are high off the ground, and procedural design issues.
