FLIGHT, 18 November 1960 793 BAC-107 Based on the H-107 project first drafted early in 1958 byHunting Aircraft, the BAC-107 is a short-range jet transport in the Viscount replacement category. It was revived when Hunting joinedthe British Aircraft Corporation in I960, and it is being vigorously promoted as a smaller partner for BAC's VC11. Numerous changeswere made as a result of Vickers' influence. One external change is the elevation of the tailplane to the top of the fin, and there are morecabin windows (26 per side). The powerplant comprises two BS.75s of 7,3501b thrust each, conferring the economy that is a dominatingdesign requirement; it is said that the 107 uses fewer gallons per mile than the Viscount that it is intended to replace. Maximum seating ina Viscount-width fuselage is 59, and cruising speed is in the 500 m.p.h. bracket. Field length is 5,000ft. The BAC 107 becomes the smallestmember of the Vickers family of rear-engined jet transports, the others being the VC11 project, the VC10 and the Super VC10. It could beready for service in 1964/1965.

CANADAIR Canadair Ltd, Post Office Box 6087, Montreal, Canada. DC-4M A pressurized, Merlin-engine development of the Douglas DC-4/C-54, the DC-4M was named North Star by TCA, who first operated it in 1947 and who still own 21. The DC-4M was bought also by BOAC in March 1949; they named it Argonaut, and three remain in Corporation service. O:her operators are EAAC, 3 (ex-BOAC), and Overseas Aviation, 6 (ex-BOAC) and Flying Enterprise, 3 (ex-BOAC). The DC-4M was described in Flight on June 26, 1947.Powerplant: Four Rolls-Royce Merlin Mk 626 of 1,760 b.h.p. driving Ham.lton Standard 13ft lin propellers.Dimensions: Span, 117ft 6in; length, 93ft 7iin; height, 27ft 6in; wing area, 1,457 sq ft. Weights: Max take-off, 82,3001b; landing, 70,0001b; zero fuel,66,0001b; capacity payload, 17,1561b; weight less fuel and payload, 46,7281b. Payload accommodation: Max seats, 55; baggage and freight volume,698 cu ft. Fuel capacity; 3,226 Imp gal (3,870 US gal).Per'ormance: Cont. cruising speed 286kt (329 m.p.h.) at 10,000ft and 70,0001b: range A (max payload), 2,075 n.m. (2,385 st.m.); range B(max fuel), 3,240 n.m. (3,730 st.m.). CL-44D-4 To fly at Montreal this month is the first CL-44D-4, adesign which promises outstanding economy and flexibility as a large cargo transport or convertible cargo/passenger carrier. Based on theBristol Britannia and its Canadair CL-28 maritime reconnaissance deri- vative, the Rolls-Royce Tyne-powered CL-44 has an exceptional payload-range capacity and should have a lower operating cost per ton-mile than any oth:r aircraft on order by the airlines; Canadair claim 40 per centbetter than the best cargo aircraft now operating. The present version, announced in 1959, has a swinging tail sectionfor direct aft loading. The fuselage will now accept a single unit 84ft long, lift wide and 6|ft high, and weighing 65,20OJb. It is this version,the CL-44D-4, for which Seaboard & Western and Flying Tiger respec- tively placed orders in May 1959 for five aircraft (with an option on five)and ttn aircraft for delivery and service in 1961. Slick Airways confirmed an order for two Forty-fours in May 1960. The RCAF have ordered afurther 12 of the military side-loading version, the CC-106. Looking ahead, by taking advantage of Tyne power increases the basicCL-44 should eventually carry payloads of up to 100,0001b, grossing around 230,0001b.

Canadair 540 This is the new production 540, built by Canadair atMontreal on Convair jigs, powered by Napier Elands. By increasing internal cabin length, standard accommodation for 48 first-class seatsinstead of 44 is available, and engineering improvements include better braking, increased fuel capacity and faster undercarriage retraction.Recent developments are a 64-seater with 32in pitch non-reclining seats. Two 52-seater Canadair 540s were sold to Quebecair in August fittedwith an APU in the tail. This provides DC current and a 74° F cabin temperature irrespective of OAT. See also Convair 540. Ten Canadair 540s are in production for the RCAF, designatedCC-109(CL-66B). Delivery to the RCAF is due to be completed this autumn.
