fjjC International. 7 November 1968 Cat m.—has been intimately involved with BAC in all phases of <; Super One-Eleven flight test programme. Capt Munro^5 aboard on the maiden flight of G-AVMH. Mr Peter jja! 'n has been the BAC pilot in charge of conversion training. 1.; tremendous air-mindedness of the German people, sten'iing from the distance between the major cities of the nat;-••'', was strongly emphasised at the time of the first public anprrance of the Super One-Eleven in Germany—on July 13-14 at tne Berlin Tempelhof open weekend. Over 7,000 Berlinerswalked through 'Mi shown jointly by BAC and BEA. On August 15 the BAC One-Eleven 500 was awarded a full and unrestricted passenger transport category ARB Certificate of Airworthiness. This was the culmination of an intensive programme of nearly 800 flying hours of home and overseas flight testing and route proving. At that time G-ASYD had logged 387 flying hours in 308 flights in the 500 development programme. The total certification task was complemented by the first three BEA production One-Elevens: G-AVMH, 'MI and 'MJ which together logged 394 flying hours. The only problem of any significance encountered during fhe entire programme was a slight overpowering of the rudder in one of the extreme sideslip design cases. This was corrected by modifying the control feel law. In consequence the 500 needs slightly more rudder in the turn than the 400. By contrast, control in the pitching plane has exhibited a slightly better landing flare.

The Super One-Eleven had been demonstrated to have met or exceeded handsomely the entire range of its contractual performance, weight and operating route mission guarantees. In particular the take-off distance is up to 8.3 per cent better and landing distance 6.7 per cent better. Cruise speed is 24kt faster, while payloads achieved to meet specified mission guarantees are up to 3,8OOlb better than promised. In addition to exceeding its guarantees, the Super One-Eleven was certificated at higher than specification design weights as follows:— Specification Certification Increase Ms mum Take-off Weight 91,0001b *41,950kg (92,4831b) 1,4831b Ma,mum Landing Weight 84,0001b *39,0OOkg (85,9801b) 1,9801b —At 3EA's request these weights certified in kilogrammes. ( >nsistently ahead of programme ever since the programme go- under way in the early months of last year, this new ^ iS of achieved performance has provided an excellents *a for the One-Eleven 500 airline programme overall.

Full scheduled Super One-Eleven services begin in Germany on November 17. BEA and BAC held the fleet- naming ceremony on September 18 at Farnborough while G-AVML took part in the flying demonstration during the week. Sir George Edwards, chairman of BAC, formally handed over G-AVMK, the fourth production aircraft, to Sir Anthony Milward, BEA's chairman, Lady Freda Milward conferred the fleet name "Super One-Eleven," which had been chosen by a BEA and BAC staff competition as the airline's marketing name for its version of the new aircraft. Further Development The next major step in the develop- ment of the One-Eleven family has already been taken and BAC is now offering the One-Eleven 500 witfi a greater pay- load-range for the expanding inclusive tour market. It is sig- nificant that the newer and rapidly increasing list of inclusive tour holiday resorts on the Mediterranean, the Black Sea and North Africa lie within a 1,000- to 1,500-mile radius of the northern European traffic centres in the UK, Germany and Scandinavia. This heavier weight 500 will also carry up to 109 passengers and be capable of non-stop journeys of up to 1,570 miles with a flight time of about 3i hours. Maxi- mum take-off weight has been increased to 98,0001b (5,5001b more than the specialised shorter-range 500). This has enabled the range with maximum payload to be increased by 57 per cent; a typical payload of 99 passengers and baggage, plus full freight, can be carried up to 1,570 miles (with full airline reserves) compared with 1,000 miles of the BEA One-Eleven 500. The powerplant is the Rolls-Royce Spey 25 Mk 512-14DW (Developed Wet) engine with water injection and maximum take-off thrust up from 12,0001b to 12,5501b at sea level and which can be maintained at ambient temperatures of up to 25 °C. The first pair of these engines were fitted to G-ASYD in July and high temperature performance with water injection was measured at Madrid in mid-August in order to obtain clearance for operation in ambient temperatures of up to ISA + 35°C. Overall this new development of the One-Eleven 500 is fully competitive with all the opposition in terms of prime cost, aircraft-mile and seat-mile operating costs.
