Abstract: The airplane cabin air quality monitoring system comprises a gas monitor. The gas monitor measures the atmosphere within an aircraft for a plurality of potentially hazardous gases. The gas monitor further comprises a plurality of gas sensors, a plurality of compensation sensors, a spectrometer, and a control system. The plurality of gas sensors, the plurality of compensation sensors, the spectrometer, and the control system are electrically interconnected. The control system manages and regulates the operation of the gas monitor. The control system generates an alert if a potentially hazardous gas is detected. The airplane cabin air quality monitoring system further comprises a docking station stores the gas monitor when the gas monitor is not in use. The docking station: 1) recharges the battery of the gas monitor; and, 2) establishes a hardwired first communication link between the gas monitor and the ACARS of the aircraft.
