Abstract
DELIVERY of the first of 12 Boeing 757's powered by Rolls‐Royce RB 211–535 E4 turbofans was made to Eastern Airlines in October and the aircraft entered service with the carrier a short while afterwards. This followed a comprehensive programme of testing which culminated in certification of the powerplant by the FAA. Flight testing included engine operating characteristics, in‐flight starts and general aircraft performance as well as flight deck electronic/engine compatibility and the collection of pertinent data for flight manual revisions. Eastern Airlines at present operates a fleet of fifteen RB 211–535 C powered 757's which will be retrofitted with the —535 E4. In the UK, Monarch Airlines' Boeing 757's will also be retrofitted with the new engines.

Abstract
HELICOPTER operations in the most demanding climatic conditions necessitate the highest standards of component reliability. Consideration of the problems involved in rotating wing aircraft in such environments was the subject of a Royal Aeronautical Society conference which encompassed a wide range of temperatures and harsh terrains. From the Norwegian Air Force, the difficulties associated with operation in — 26°C in the treeless landscape or Tundra, of the Arctic, were described. For Norway, the main area of interest and responsibility lies in the Arctic islands of Svalbard and the sea areas between Svalbard and the mainland of Norway. Fisheries take place up to 82° latitude, which is something of a record. There are also (Russian) coal mining areas of Svalbard.

Abstract
A system which has been in service with Trident and other types of aircraft for some years is the Plessey PV 726A which was one of the first to incorporate expanded facilities to acquire AIDS information. It consists essentially of a data entry panel which permits the insertion of flight identification data, self‐test facilities, ON/OFF switching and fault indication, an acquisition unit, transducers, DFDR or accident recorder, and the quick access recorder.

Abstract
Developed from a wartime indentification system, Secondary Surveillance Radar (SSR) has become a means whereby the air traffic controller can be provided with an immediate display of an aircraft's identity, range, azimuth and height. Also, since SSR is a communication channel, further special information can be supplied such as indication of in‐flight emergency communications failure or the detection of a “hi‐jack” situation.

Abstract
THE Engineering Division of Dan Air Services was formed in 1954 when the parent company, Davies and Newman Holdings, decided that the successful operation of its (then) newly formed airline required in‐house maintenance and the first such facilities were established at Blackbush which was then a thriving airport. The first engineering base was established at Lasham where the environment offered scope for the planned long‐term expansion. Dan Air's reputation during the early years was mainly as a freight airline but it gradually became a passenger carrier and in 1960 moved to its present operating base at Gatwick. Fleet expansion and the increase in the overhaul facility at Lasham coupled with the one‐time very busy North Atlantic operation were further high spots for the airline but by 1978, the transatlantic traffic had fallen away and the carrier sought expansion in other fields. The base at Lasham had meanwhile again expanded and with the departure of the Boeing 707's and the Comets, the fleet was centred around the 748's. The additional hangar space available now enabled the company to offer their own services to other aircraft operators and this venture was so successful that a second engineering base was opened at Manchester early in 1976 to service the airline's BAe One‐Eleven and 748 aircraft. It has remained a centre for these types to the present day with the other aircraft of the airline, now including the BAe 146, being maintained at Lasham.

Abstract
WHEN the Airbus Industrie A320 makes its first flight next year it will be equipped with two CFM 56‐5‐A1 turbofans of 25,000 lb thrust each. This engine is scheduled for certification in August, 1987 and will enter service in the A320 early in 1988. Following closely is the International Aero Engines V2500 turbofan which is being developed at thrust levels of 23,000 and 25,000 lb and is due to be certificated in April, 1988 and enter service (at the higher thrust level) in ther A320 early in 1989. Both these powerplants make extensive use of the expertise gained over recent years by engines in service and which has been improved and refined to produce the higher thrust/‐weight ratio and lower specific fuel consumption (SFC) anticipated in current turbofans.

Abstract
CURRENTLY operating on some of the longest sectors of any of the world's carriers, Cathay Pacific Airways pioneered a daily London — Hong Kong service in 1980 which it operated with a stop at Bahrein. A further advance was made in July, 1983 when the airline added a weekly non‐stop service from London. In May, 1984 the airline began flying from Hong Kong on a non‐stop basis for a weekly service which was operated until October when adverse weather made it necessary to keep this as a one‐stop facility. The non‐stop operation to London will however, be resumed in the middle of 1985. More evidence of the growth of long haul routes, in this case to Continental Europe, came with the start of a one‐stop operation between Frankfurt and Hong Kong which is undertaken four times a week and began in April, 1984. The airline also operates three times a week to Vancouver non‐stop from Hong Kong, which is its first service across the Pacific. Overall, the Cathay Pacific network serves 17 countries and includes destinations that range from Seoul in the north to Melbourne in the south, westward to London and east to Vancouver.

Abstract
In service with the launch customer Dan‐Air since May, 1983, the British Aerospace 146 has shown its ability to serve airports hitherto not available to passenger jet airliners and has also undertaken, on a day‐to‐day basis, rapid turnround and transit stops requiring only the minimum of ground support facilities. A typical sector operated by Dan‐Air with this aircraft is to Bern, the Swiss capital, with a journey time of about 1 hour 30 minutes. The runway at this airport is only 1,300 metres in length, so that operation has to be with equipment of suitable performance. As well as this destination, the 146 also operates on the airline's scheduled service network from Gatwick to Dublin and Toulouse and to Newcastle, Bergen and Stavanger.

Abstract
OPERATING to increasingly severe noise and NOx emission levels and at the lowest Specific Fuel Consumption (SFC) attainable, current turbofan engines represent considerable advances in all respects on powerplants of only a few years ago. Nevertheless, the demand for even larger engines has meant that the major manufacturers are making considerable efforts to develop operating cycles and improved components to attain optimum performance for the foreseeable future.
