FreeFlight Systems, of Waco, Texas, released a 4 MB navigation database memory upgrade for its Approach Plus GPS Navigation Management Systems (including the I/O models) and equivalent legacy equipment with the Trimble name. The upgrade was developed and implemented in collaboration with Jeppesen, the company said. With the upgrade, pilots will have continued access to the Jeppesen NavData which includes a database of information on airports, approaches, SIDS, STARS, VORs, NDBs, intersections and airspace boundaries. FreeFlight said. “With this 4 MB upgrade our customers will experience at least a doubling of the nav data memory size which will enable them to take advantage of the continued growth of the Jeppesen avionics database,” said Tim Taylor, president and CEO of FreeFlight Systems.
