NASA Develops New In-Flight Fire Sensors

Hopes To Eliminate Threat Of False Alarms

Second to an actual in-flight fire, the threat of such a fire is one of the most unnerving possibilities a pilot can face. Now, NASA says it's come up with a new fire alarm system agency officials believe will greatly reduce the number of false fire alarms on board aircraft.

Officials say the new generation of sensors are so sensitive they can reduce the possibility of fire in the cargo hold to virtually zero.

That's because the sensors detect and eliminate the causes of false alarms -- dust and other airborne particles often found inside aircraft. Researchers at the Glenn Research Center in Cleveland, OH, came up with the idea of comparing gas concentrations and smoke particle sizes to detect a real fire as opposed to a false alarm.

The new system can't be installed, of course, until the FAA signs off on it. But already, NASA officials are looking at the possibility of using this same technology aboard spacecraft.
