Aviation Instruments Encrypt Engine-Monitor Data

kitplane01 writes "Airplanes engines need to always work, and are monitored by engine monitors. JP Instruments' engine-monitor units have begun to encrypt the data output of its monitors so it can't be read by third-party software. Whether this is to protect itself liability-wise or to discourage competitors is unclear. It seems the company is working on a fix, which may require a fee from users to translate the file format."
