BUSINESS AVIATION MANDATE GUY NORRIS / LOS ANGELES Citation 500 is latest RVSM target Honeywell secures FAA STC approval for avionics package as new regulations for turbine-powered aircraft take effect Honeywell has clinched US Federal Aviation Administration supple mental type certification (STC) approval for an avionics package to enable Cessna Citation 500 opera tors to meet Domestic Reduced Vertical Separation Minimum (DRVSM) requirements. The DRVSM mandate, scheduled ENGINE for implementation in the USA and Canada on 20 January 2005, req uires aircraft at FL290-410 (29,000- 41,000ft/8,850-12,500m) to be capable of regulating their altitude more accurately so controllers can space aircraft at 1,000ft intervals. Around 6,000 turbine-powered business aircraft are affected, and as demand for STCs increases over the next few months Honeywell is expected to unveil further upgrade packages. Unlike previous DRVSM STCs developed in collaboration with other companies, Honeywell has worked alone to gain the latest approval - which covers Citation Honeywell gives AS907 turbofan redesignation Honeywell has redesignated its latest AS907 turbofan the HTF7000 to reflect the company's new nomenclature for new engines. The numbers denote the thrust class, and the letters indicate whether the engine is a turbofan, turbo prop or turboshaft. The 7,0001b thrust-class (31 kN) HTF7000 powers Bombardier's Challenger 300 super mid size business jet. Honeywell's existing engines will continue to carry des ignations reflecting their varied origins. The TFE731 turbo fan and TPE331 turboprop are former Garrett engines that date from before the merger of Allied and Signal in 1985. The LF507 turbofan and LTS101 turboshaft were devel oped by Lycoming, which was acquired by AlliedSignal in 1995. Development of the AS900 family began in 1998, before AlliedSignal and Honeywell merged in 2000. A new 5,000lb thrust-class engine, for which the com pany is seeking a launch customer and which was previously known as the AS905, would be designated the HTF5000 under the new naming convention, says Honeywell. The HTF7000, meanwhile, will retain its origi nal AS907 designation for legal and regulatory purposes, the company says. 500 models up to and including serial number 274 - and modifica tions will be performed by autho rised Honeywell Bendix/King dealers. Cessna has decided not to pursue an STC for these early mod els, but is offering and developing packages for other Citation types in service, it says. The Honeywell package includes AM 250 altimeter systems with a KFC 325 flight control system (FCS) and EFIS 50 electronic flight instrument system (EFIS), with the altimeters alone being available to aircraft already equipped with the FCS and EFIS. Honeywell has partnered with Elliott to provide an avionics package that will enable the Beechjet 400 and Mitsubishi Dia mond 1/1A to meet both DRVSM and terrain awareness warning sys tem requirements. IN BRIE MEGGITT APPROVAL Meggitt Avionics has won sup plemental type certification (STC) for its Magic 2100 digital autopilot in Twin Commander turboprops. The approval covers most of the Gulfstream-built Jetprop series of Twin Commanders, including the Commander 690C/Jetprop 840, 690D/900,695/980 and the 695A/1000. Mineral Wells, Texas-based Meggitt has also received an STC for installation of the Magic 2100 autopilot in the Beechcraft King Air 90 series. SOFTWARE TRAINING Adam Aircraft has picked ElectronicFlight Solutions to pro vide computer-based avionics training software for the A500 piston twin. The software will allow A500 buyers to train at home before training in the air craft. Adam plans to use training standards for technically advanced aircraft as the blue print for its A500 in-house training programme. DELIVERY Jet Aviation finishes BBJ Jet Aviation Basel has com pleted and delivered a second Boeing Business Jet (BBJ) to an undisclosed Middle East- em customer. The head-of- state aircraft seats up to 44 passengers and five crew, and includes a first-class seat ing area, a forward and aft club seating area and a forward lounge. REGULATION FAA extends time for ETOPS study Business aviation has been granted a 60-day extension to comment on the US Federal Aviation Admin istration's notice of proposed rule making (NPRM) on extended range multi-engine operations (ETOPS). The rule would prevent any char tered business jets - except appropri ately equipped aircraft - flying fur ther than 180min from a usable diversion airport, says the US National Business Aviation Associa tion (NBAA). "The extension is good for the business aviation commu nity, giving us additional time to complete a thorough review of the rule and its impact on FAR Part 135 operators," NBAA says. The NPRM, which extends ETOPS for the first time to 135 oper ators and to trijets, will affect opera tors of older business jets with an inadequate single-engine range, the industry fears (Flight International 25 November-1 December 2003). ETOPS-equipped aircraft may fly 240min from diversion airfields, so there is virtually no route they may not fly. ETOPS rules will probably affect fractional ownership opera tors as the industry strives to equate Part 135 with Part 91 Subpart K operations, governing fractionals. 20 13-19 JANUARY 2004 FLIGHT INTERNATIONAL www.flirjhtinternational.com
