![]() Equipment problems, such as alarms sounding when they shouldn't or failing to sound when they should, accounted for about a quarter of the 100 incidents involving warning horns cited in the ASRS from the mid-1990s through February, according to Travel Weekly's analysis of the data. Pilots have frequently misinterpreted the in-flight warning as an indication of a preflight danger that is no longer a concern and have thus considered it a false alarm.Īdding to the confusion is the fact that pilots often contend with false alarms and related pressurization equipment miscues in flight. Before takeoff, it warns pilots if the aircraft is not configured properly for flight. Perhaps the most important is that in the 737, the horn serves a dual purpose and thus is an ambiguous alarm. ![]() And in fact, there are several reasons why this is happening. It might seem counterintuitive that commercial pilots, a group that prides itself on emphasizing safety and professionalism, would simply ignore an alarm when the consequences are so potentially deadly. In fact, pilots kept ignoring the horn even after the FAA, prompted by the Helios 522 crash, issued an emergency airworthiness directive the following year requiring more emphasis, in manuals and in training, on heeding the alarm. I don't think it's something people just ignore."īut ignoring the horn is exactly what Boeing 737 pilots have been doing for years, even after it became known that the Helios 522 crash was caused by the crew's failure to respond properly to the warning, with such deadly consequences. I don't think anyone takes the cabin altitude horn lightly. "That warning is very important to pilots. Karen Kahn, a longtime commercial jet pilot and author of the book "Flight Guide for Success: Tips and Tactics for the Aspiring Airline Pilot," said of pressurization problems that can result in hypoxia. "It's considered one of the mega-emergencies," Capt. The latest came late last month, when the agency mandated briefings instructing pilots to heed the altitude horns.Īt the same time, Boeing began building an improved altitude warning system into its new 737s as it proceeds with plans to retrofit the more than 5,000 737s already in service with FAA-approved signal kits. However, the FAA has taken several proactive steps since the crash.
