FLIGHT International, II October 1980 1449 nav receiver to the desired frequency simply by punching in its three-letter code-name. FMS 90's data base also includes the 2,500-odd airports in the world which have a paved runway more than 4,000ft long. This data can be updated each month simply by running a punched tape through a hand-held unit plugged into FMS 90. When FMS 90 is used in area navi gation (RNav) mode to chart a course between DMEs and VOBs, it auto matically calculates offsets, freeing the pilot from this task. FMS 90's keyboard can be used to tune radios remotely to the desired frequency, to set transponder codes, and to tune the ADF. If desired, the coram equipment of either pilot or both pilots can be set directly. Comm and Nav data for FMS 90 can be displayed on the Collins WXR- 300 colour weather radar screen if one is fitted to the aircraft. Lastly, FMS 90 is designed to link up with the Collins FCS-80 flight control sys tem and ADS-80 air data system. The ADS-80 includes the new Collins VNI- 80 vertical navigation system, which can tell pilots when to begin their descent, for example. First application of FMS 90 is an Israeli Aircraft Industries Westwind 2, belonging to Atlantic Aviation. The aircraft was at the show and open to inspection (see cockpit picture page 1420). Collins says that FMS 90 will cost less than $100,000 and that it will be about a year before the unit becomes widely available—the first year's production is already sold out. King had its KNS 81 integrated Nav system and KI 229 radio-magnetic indicator (RMI) on display at the NRAA show for the first time. The KNS 81 features nine waypoints and a built-in, automatically tuned glide- slope receiver which eases panel space and simplifies maintenance. Distance and bearing to Vortac station or RNav waypoints are available, but require Pratt & Whitney Aircraft of Canada displayed a mockup of its PT7 turbo prop for the first time. The engine is a completely new design and has al ready been selected to power de Havilland's DHC-8 and Embraer's EMB-120 Brasilia. Pratt & Whitney first announced PT7 in 1979 and completed running of a demonstrator early this year. Full go-ahead for the engine was given in July and Pratt & Whitney expects to run its first complete engine in the first quarter of next year. a separate DME set and RMI. The KNS 81 has a non-volatile memory and its list price is $4,650. Delco Electronics introduced an im proved version of its Carousel IV-AX inertial navigation system, featuring an increase in memory from 6,000 to 8,000 words, plus extra interfaces. The memory allows a seven minute start up time, fuel management functions, range and bearing information and additional waypoint definition. List price of the improved unit is $115,800 —$900 more than its predecessor. The extra memory will be available as a retrofit and will cost $2,000-$4,500 de pending on set age. Global Navigation featured a new version of its VLF/Omega navigation system, GNS-500A series 3, which has a monochrome CRT display and extra functions. Up to 127 waypoints can be stored in the unit, each identified by a code-name up to five characters long. The waypoints are stored as route flight plans and the order of waypoints in a particular route can be reversed at the touch of a button. List price of the series 3 is $49,950 and deliveries are due to begin in November. Engines Flight-testing of a PT7 in the nose of Pratt & Whitney's Viscount is due to begin in October next year. Roughly 200hr of flight-testing is planned, including performance, con trols behaviour and re-lights at alti tude. There are 11 engines in the development programme and certifi cation is scheduled for mid-1983. Delivery of prototype PT7s to Em- Left Collins claims its FMS 90 flight manage ment system to be the ultimate in business aircraft navigation. Above Canadian Mar coni displayed this production-standard version of its CMA 923 flight advisory computer Retrofits for GNS-500A series 1 and series 2 sets will be available from the second quarter of 1981, at a list price of $15,000 and $9,750 respec tively. Becker Flugfunk of West Germany made its NBAA debut, displaying its standard range of Comm and Nav equipment. Becker's products are aimed at the market between light aircraft and executive jets. Canadian Marconi has now sold 25 sets of its CMA 776 status display system, which was introduced at last year's show. Potential customers in clude the US Army, which is equip ping its UH-60 Black Hawk avionics demonstrator with an example. Canadair is also interested in making CMA 776 standard on Challenger E. The company displayed its produc tion standard CMA 923 flight advisory computer, also introduced at last years NBAA. The first flight of the unit is due to take place within the next two months, aboard a USAF Sabreliner. Since last year Canadian Marconi has opened a sales and sup port office in New Jersey. The office is primarily intended to support east coast operators, for which New Jersey is typically the hub of their routes. Foster AirData's latest offering is its RNav 612, five-waypoint area navi gation system. The unit features auto matic selection of waypoints. braer is due to begin in early 1982, while de Havilland will get its engines in mid-1982. Deliveries of production-standard engines to Em- braer and de Havilland are due to start in late 1983 and early 1984 re spectively. Embraer has not specified how many PT7s it has ordered, but de Havilland has ordered 200 engines— the company has more than 75 firm aircraft sales. Embraer has specified the PT7-A1 for its Brasilia. The engine is flat-rated at 1,500 h.p. and
