| 摘要： | Currently, holdover time performance for aircraft deicing and anti-icing fluids under snow conditions are determined from outdoor tests on flat plates in natural snow. The Federal Aviation Administration Airport and Aircraft Safety Research and Development Division has sponsored research to do similar tests under indoor laboratory conditions. Such indoor tests would lead to a more timely and improved assessment of a new fluid's performance without relying on outdoor snow conditions. During past investigations, when similar tests were conducted in laboratory cold rooms, the resulting holdover times were significantly different (typically shorter) from those produced outdoors in natural snow conditions. This difference was attributed to the effects of wind. Recent research at the National Center for Atmospheric Research has produced indoor procedures using temperature-controlled test plates that accounted for the effects of wind and produced holdover time results that more closely matched those obtained from outdoor snow tests. |
