Aviation Technology Debuts AltAlert Personal Cabin Pressure Monitor
The portable device can help pilots detect cabin pressurization failure before hypoxia sets in.
Aviation Technology’s AltAlert provides audible and visual alerts when cabin altitude climbs to dangerous levels. The device can fit in a pocket or be mounted on the aircraft window.

While aircraft that fly in the flight levels have pressurization-failure warning systems, accidents involving apparently hypoxic pilots keep happening. Stacy Pappas Sawaya, president and CEO of Carlsbad, Calif.-based Aviation Technology, researched these types of accident and invented a new portable warning device–the AltAlert “personal cabin pressure monitor”–that pilots can use to help detect a pressurization failure well before it causes hypoxia. AltAlert can also help remind pilots flying unpressurized high-altitude aircraft that it’s time to don oxygen masks.
