Fokker Services and FreeFlight Systems have formed a partnership to provide a low-cost means to modernize the airborne navigation system without replacing existing equipment or making extensive changes to the aircraft.
This dual system with certification is about one-third of the cost of a new Flight Management System (FMS), and requires about 100 man-hours to install, according to company officials.
The modification enhances accuracy and performance of existing IRS/FMS systems without GPS capability by integrating GNSS/SBAS data. The system was originally designed for Fokker 70/100 aircraft, but will work equally well for business jets. The upgrade will allow flight crews to fly GPS-based RNAV for the entire flight (SID, enroute, STAR), in addition to allowing non-precision GPS approach capability. The system will improve situational awareness and provide lateral guidance based on GNSS. Moreover, the aircraft will be able to operate in remote and oceanic regions, and will be approved for terminal area navigation operations in European and other airspace, officials add.
