WQAR Operation Overview
The primary purpose of the WQAR is to record and store flight data provided
to it by a data acquisition unit such as a DFDAU or FDIMU. Then, while the
aircraft is on the ground, it wirelessly transmits that data to a base station
using high-speed 3G/4G-like cellular technology (where available). If unable
to transmit, a backup encrypted copy of your data is stored on the removable
Compact Flash (CF) card.
