What companies in the past have said about AMSADD.... ...the system puts the vectors back in the cockpit....it allows the pilot to apply judgment to a clearance possibly issued inadvertently to another... Airdata Inc., Columbus, Ohio   ....there is no substitute for having this information available in the cockpit....(AMSADD) is an excellent idea.... * Collins Radio Group, Rockwell International, Cedar Rapids, Iowa * Co-designers of GCAS   ....I know you are aware that ALPA cannot endorse specific products. But the ALPA ATC Committee feels strongly that this is a problem area which has not been solved, and badly needs a solution....a device such as you have proposed (AMSADD) could make a dramatic impact on the safety of flight.... ALPA, Washington D.C.   ....the concept that you propose is interesting and shows good potential, and we would very definitely be interested in purchasing this equipment if it were proven and available.... Continental Airlines
