摘要
Onboard systems and methods for early detection that an aircraft is approaching a volcanic (ash) plume or a gas plume having a concentration of a volcanic gas which would be toxic to humans. The detection method generally comprises the steps of measuring the concentration of one or more volcanic gases in air circulating in a space inside an aircraft and generating an alarm when one or more measured volcanic gas concentrations exceed a respective user-specified threshold or when a pattern of volcanic gas concentration is recognized with a user-specified confidence level. These systems are configured so that the alarm indicates the proximity of dangerous levels of either a volcanic gas or of volcanic ash. In particular, the detection system utilizes the air circulating through an aircraft cabin or cockpit to enable use of low-cost, carry-on electronic devices.
