WEBVTT 00:00:00.426 --> 00:00:01.586 A:middle Hello, my name is Bill Rieke. 00:00:02.306 --> 00:00:03.786 A:middle I'm chief of flight operations 00:00:03.786 --> 00:00:05.406 A:middle at the NASA Glenn Research Center. 00:00:06.796 --> 00:00:09.156 A:middle This ground icing web site you've entered has some 00:00:09.236 --> 00:00:12.516 A:middle excellent information for pilots with a wide range of experience. 00:00:13.856 --> 00:00:15.266 A:middle For the experienced commercial 00:00:15.456 --> 00:00:19.196 A:middle or airline pilot it may just reinforce the knowledge you have 00:00:19.236 --> 00:00:20.876 A:middle acquired over your years in the cockpit. 00:00:21.696 --> 00:00:23.386 A:middle Or, it really could be very informative 00:00:23.566 --> 00:00:25.976 A:middle and expand your knowledge base in a specific area. 00:00:26.116 --> 00:00:28.156 A:middle On the other hand, 00:00:28.156 --> 00:00:30.456 A:middle it may actually dispel some long held theories 00:00:30.456 --> 00:00:32.446 A:middle that have been handed down and accepted 00:00:32.446 --> 00:00:33.776 A:middle as gospel for many years. 00:00:35.236 --> 00:00:37.376 A:middle For the newer and less experienced pilot it should be 00:00:37.376 --> 00:00:39.106 A:middle looked at as a valuable reference 00:00:39.446 --> 00:00:42.226 A:middle from knowledgeable sources that could be extremely helpful 00:00:42.226 --> 00:00:44.256 A:middle when the 'chips are down' and 'go, 00:00:44.256 --> 00:00:45.976 A:middle no-go' decisions have to be made. 00:00:47.396 --> 00:00:48.836 A:middle Keep in mind, used properly; 00:00:49.326 --> 00:00:51.776 A:middle this site has a substantial amount of information 00:00:52.326 --> 00:00:56.306 A:middle on aircraft ground de-icing, portions of which, are valuable 00:00:56.306 --> 00:00:58.106 A:middle for even the most experienced pilot. 00:00:59.136 --> 00:01:03.076 A:middle Remember, don't take off with ice on the critical portions 00:01:03.076 --> 00:01:05.946 A:middle of the aircraft - you may be lucky and get away with it, 00:01:06.536 --> 00:01:08.446 A:middle but even very small amounts of ice 00:01:08.566 --> 00:01:10.926 A:middle on critical surfaces can be catastrophic. 00:01:12.316 --> 00:01:16.006 A:middle Ground application of anti-icing fluids can protect the aircraft, 00:01:16.516 --> 00:01:19.466 A:middle but only for a limited time that can be VERY limited, 00:01:19.516 --> 00:01:20.976 A:middle depending on the type of fluid 00:01:21.286 --> 00:01:23.046 A:middle and the atmospheric conditions at the time. 00:01:24.696 --> 00:01:28.446 A:middle ALL fluids will flow off during some portion of the takeoff roll 00:01:28.716 --> 00:01:31.226 A:middle and NONE of them will protect you in the air. 00:01:32.606 --> 00:01:35.636 A:middle Remember, the pilot in command, is ultimately responsible 00:01:35.676 --> 00:01:39.136 A:middle to ensure critical surfaces of the aircraft are free of ice 00:01:39.386 --> 00:01:41.376 A:middle or any kind of frozen contamination.
