Page 21 - We have a vote on the floor. The committee will stand in recess, subject to call of the Chair. Hopefully, it will not be longer than 15 minutes. (Recess.) (The attachment follows:) ATTACHMENT I DESIGN PROPOSAL FOR LOW COST "MINI-CAS" FOR GENERAL AVIATION Wilcox Electric, Inc.
Page 12 - FROM MISSOURI Senator EAGLETON. Thank you, Mr. Chairman, and I will be as brief as possible, I appreciate the indulgence of the committee in permitting me to introduce witness No. 6, Anatole Browde, who will appear in regular order, but thank you for introducing me at this time. May I say how I appreciate the subcommittee interest in these hearings. Just this year's record alone demonstrates all too vividly the serious problem of collisions between aircraft and between aircraft and fixed obstacles....
Page 55 - I would like to introduce Mr. Ted Linnert, director of the Engineering and Air Safety Department of the Air Line Pilots Association. Senator CANNON. The attachments will be made a part of the files and we will certainly give them full consideration. Earlier one of our witnesses testified concerning the area navigation system, that this might reduce the incidents of exposure.
Page 61 - Air Space Users Study," also House Report 1272 entitled "Air Transportation Development and Air Space Use Problems." On June 13, 1958, the President submitted a message to Congress recommending the development of an independent agency, saying: Recent midair collisions of aircraft, occasioning the tragic loss of human life, have instituted the need for a system of air traffic management which will prevent them, within the limits of human ingenuity. In this message, accordingly, I am recommending to...

At an ATA meeting in April, 1965, Collins reported on the results of its studies and McDonnell Aircraft showed the equipment they planned to use in their flight test operation later that year. The airlines were sufficiently impressed with McDonnell's system to invite their experts to brief the Airlines Operations Conference in September, 1965. After this briefing,...
Page 117 - ... 1963 In the fall of 1963, FAA gave Collins a contract to study CAS techniques by simulation. 1965 A report of the Collins study was forwarded to FAA in mid-1965. In essence, Collins told FAA that the simple time-frequency system is the most promising, that it works quite well for the enroute case, but has some limitations in the terminal area — where aircraft are most likely to be maneuvering in flight. At an ATA meeting in April, 1965, Collins reported on the results of its studies and McDonnell...
Page 126 - Thank you again for this opportunity to testify. I will be happy to answer any questions you may have.
Page 117 - ... developed into a CAS. Two million dollars worth of airline orders were placed with Collins. But in the development work that followed, Collins discovered that normal aircraft movements in flight prevented their airborne doppler radar from making reliable collision prediction, or could create erroneous predictions in a significant percentage of cases. This eliminated the CAS feature of the Collision proposal. So the proposal was withdrawn while Collins continued its analytical work, which has...
Page 7 - Phantom Jet provides a sorrowful example of a midair collision that should outrage the consciences of all Americans as 49 lives were needlessly lost. In conjunction with this tragic air collision, I am aghast that the National Transportation Safety Board's recommendation issued November 9, 1971, urging the FAA to take the following action : Coordinate with the Department of Defense, and, in areas where a large intermix of civil and military traffic exists, develop a program to insure that appropriate...
Page 117 - Morrell, following their publication in the mid-50's of the first accurate description of the fundamental physics of the airborne collision avoidance problem. 1959 The ATA Collision Avoidance Committee (formed in 1956) continued to monitor and encourage CAS investigations until 1959, when FAA created its Collision Prevention Advisory Group (COPAG). Thereafter, ATA took part in CAS work as a member of COPAG.
