So I got a Pathfinder Triple Sensor for Christmas (this one
, for reference) while on vacation on the other side of the country. On the commercial flight back (a Delta MD-88
or something), I clicked onto the altimeter just to see what it would read. It gave a reading of 32,800 ft (its maximum reading
). I asked a flight attendant what our current altitude was, and was surprised to hear we were at 33,000 ft. After that I updated it frequently, and was able to watch the altitude slowly go down as we descended, stopping as we circled the airport for several minutes (reading about 6000 ft), and returning almost to zero after we touched down. My understanding of how this watch works
(pressure/temperature of surrounding atmosphere) and how airplane cabins work (pressurized to approximately 7000 ft
) dictate that this shouldn't have happened
As far as I know, no one died of hypoxia
on the flight, so, what gives?
