ASRS to Conduct FANS Study
s We received a FANS message to climb to FL330 (we were
at FL310). The Captain printed the message, verified the plane number and tail flight number, but somehow missed the phrase ‘at XA40Z.’ We climbed at XA28Z and reported level at FL330. ATC advised us to return to FL310 which we immediately did. This problem could be avoided if conditional clearances were not given… This ASRS report filed by a First Officer refers to a new technology called FANS (Future Air Navigation System) that is currently being introduced aboard commercial air carrier aircraft such as the B-747-400. FANS enhances aircraft communications and navigation through a data link (electronic non-voice) connection between the aircraft Flight Management Computer (FMC) and ATC facilities. This data link is supported by ground and satellite relay stations. The messages relayed through FANS data link may involve clearances, flight crew requests, route modifications, and other types of routine and emergency communications. The FANS system currently is being operated by several international carriers on Pacific oceanic routes as a partial substitute for ARINC and other types of voice communications. NASA has asked ASRS to collect operational experiences from pilots who have used FANS within the last 6 months. Pilots are encouraged to submit both beneficial experiences as well as operational difficulties they have encountered with the system. ASRS will conduct the FANS study through a number of voluntary telephone interviews, known as structured callbacks, with participating pilots. The information gathered by ASRS will help NASA recommend appropriate ways to improve FANS technology, including training, documentation, and future implementations of data link technology. Only reports from air carrier pilots using the FANS system will be solicited for the study. Pilots who submit reports to ASRS on FANS incidents and experiences will be contacted by a telephone call to the phone number given on the ASRS report form ID strip. Reporters who agree to participate in the study will be able to discuss the incident they reported in detail with an ASRS analyst, at a time that is mutually convenient. Participation in the ASRS study is entirely voluntary. As with all ASRS report information, all personally identifying data (names, company affiliations, etc.) will be deleted before the research results are given to NASA. Only aircraft make/model information will be retained in the ASRS data. If there are any questions that a reporter prefers not to answer, the ASRS analyst will skip those questions. As soon as the interview is complete, the report ID strip will be returned to the participating pilot, with no record of the reporter’s identity retained by ASRS. ASRS reporting forms are available for downloading from the ASRS Web site at http://olias.arc.nasa.gov/asrs. Forms may also be obtained from FAA Flight Standards District Offices and Flight Service Stations; from participating air carrier companies; or by written request to ASRS, P.O.Box 189, Moffett Field, CA, 95035-0189.
Flight crews routinely listen for unusual noises in the aircraft, but the racket this crew heard was never covered in any training syllabus. A First Officer reports:
s Departed the gate and found out that there was a [short] ground stop to our destination. This turned out to be about 3 hours. The Flight Attendants were doing a good job of keeping the passengers content even though we were not making any progress towards our destination. We got word that we could start our engines and get ready for takeoff. We had just run up the power and started our takeoff roll when we heard loud screaming and hollering from the back. We discontinued the takeoff roll and advised Tower that we needed to get off the runway. Upon exiting the runway, we checked with the

Flight Attendants to see what the problem was. Apparently the passengers were so happy to be taking off that they all started cheering. We had no way of knowing this at the time, of course. We then went back and got in line for departure again. This time the takeoff roll was uneventful and we proceeded to our destination. Most of the passengers thought it was humorous that we would stop for the noise, but as we explained, we had no idea what the seriousness of the problem was or could be. Just another glamorous day in aviation. Flight crews have come to expect the occasional cheer on landing, but rarely hear such praise on takeoff.
