Clay Lacy Aviation, working with Universal Avionics and Envoy Aerospace, is hoping to secure certification next year for a Universal Avionics package that would enable Gulfstream IV and IVSP aircraft to meet new equipment requirements for North Atlantic crossings.
Clay Lacy plans to begin installation of the package – which includes FANS 1/A+, CPDLC, Link 2000+ and ADS-B – in January. The package initially will be installed on a G-IVSP, with certification expected to follow in April. Clay Lacy will complete the installation and sell the STC package at its Van Nuys, Calif., facility, and will also make the package available to Universal Avionics authorized dealers.
Clay Lacy sees a market of about 500 GIV and GIVSP aircraft for the STC package. The California-based business aviation services company also hopes to add GV aircraft to the STC after it secures initial certification for the GIV/IVSP.
The retrofit would be the first of its kind for the older Gulfstream IV models, providing an upgrade to the technology incorporated on the successor G450, along with the G500 and G650 ,Clay Lacy says, and it comes as the North Atlantic Track (NAT) mandates are implemented. Beginning this year, aircraft must be equipped with FANS 1/A, CPDLC and ADS-C equipment to fly between FL360 to FL390 in the NAT-organized track system. That is expected to be expanded in 2015 to FL350 and eventually to FL290 by 2020. FAA next week is expected to publish details of the phased-in requirements.
FANS 1/A+ is already widely used by commercial aircraft, but Clay Lacy notes only a small number of business jets incorporate the technology. It replaces HF radio position reports with satellite-based position reports. The reports are sent directly to air traffic control from the aircraft’s onboard flight management system (FMS) and data link system.
Clay Lacy notes the FANS 1/A + system improves accuracy and timeliness of the reports and cuts down on potential confusion that could surround verbal reports. It also allows ATC to reduce minimum flight separation requirements. Clay Lacy also notes it will reduce flight time and in turn lower fuel burn.
