806 FLIGHT, 23 November 1961 Commercial Aircraft of the World . . . The Breguet 942 may eventually be operated on French domestic routes by Air Inter. The military Br94/ is shown tracts with Eastern Air Lines and United Air Lines for 40 aircraft each.On May 16, 1961, American Airlines signed a letter of intent to purchase 25 727s for delivery in 1964 and this led to a firm contract being signedon August 10, Earlier, in March 1961. the first export breakthrough came with an order for 12 from Lufthansa. The first production jig wasloaded in October 1961, and, according to a Boeing schedule published last January, the first aircraft will be rolled out in August 1962 and willfly in November 1962. Deliveries to Eastern and United are due to start towards the end of 1963. General configuration of the aircraft is similarto that of the de Havilland Trident, although the 727 is a rather larger aircraft. Fuselage cross section corresponds with that of the otherBoeing jet airliners although the accommodational length is less. Particular emphasis has been placed on field performance, which is wellbelow 6,000ft in standard conditions. Flaps are triple slotted and the leadine-edge flaps are of the Krueger type. Powerplant: Three Pratt & Whitney JT8D-1 turbofans of 14,0001bthrust each. Dimensions: Span. 108ft 7in; length, 135ft 5in; height, 34ft; wing area.1.650 sq ft; sweepback at quarter chord, 32".

Payload accommodation: Freight hold volume, 850 cu ft; cabin length.72ft 8in; max width, 139in; cabin height, 90.9in: door sizes, as 707 except for ventral door.

BREGUET Societe Anonyme des Ateliers d' Aviation Louis Breguet,24 Rue Georges Bizet. Paris 16e. France. Breguet 763 Deux Ponts The Breguet 763 stems from the earlierType 761. the design of which was started in 1944 and which flew for the first time on February 15. 1949. The Deux Ponts fuselage isthe same as that of the 761 but the span is increased and the wings reinforced; twelve 763s were ordered by Air France in 1951 (it is operatedby the French airline under the name Provence) and the prototype flew for the first time on July 20. 1951. The Service version, the Type 763,is known as the Sahara, and 15 of these were ordered in 1956. Powerplant: Four Pratt & Whitney R-2800-CA18s driving HamiltonStandard propellers. Data appeared in Flight for November 20, 1959, page 583. Breguet 940 Integral A STOL research machine built to FrenchGovernment contract, the Integral first flew on May 21, 1958. Its trials have substantiated Bfcguet's belief that good cruising speed and carry-ing capacity are aerodynamicaily reconcilable with STOL capabilities without the need for a rotor. The basic concept is the "vectored slip-stream" : four big interconnected propellers blow across the whole span of a normally loaded wing which is generously endowed with full-spandouble-slotted flaps. Powerplant consists of four Turbomeca Turmo II turboprops of 400 h.p. each. Gross weight is 16.0001b. Flight reference: May 30, 1958. Breguet 941 and 942 These two aircraft differ only in their fuselages. the 941 being unpressurized, and the 942 having a circular-section pres-surized fuselage. The military 941 was built to Government contract. and flew on June 1, 1961. powered by four Turbomeca Turmo HIDturboprops. Originally it was planned to install four de Havilland (General Electric T58 licence) Gnome turboprops of 1,250 s.h.p.: thisinstallation is now offered as an alternative for both the 941 and 942. Consumption of the two engines is said by the manufacturer to beequivalent, so that performance figures are the same for both the 941 and 942. The Gnome installation, being lighter, allows a payload bonusof 4501b. The 941 and 942 are of course developed from the 940 researchvehicle, benefiting from all the successful flight testing so far achieved, and they fill a unique requirement for very-short-field (800-1,500ft)performance—allowing, for the first time, a fixed-wing vehicle with relatively low operating cost to compete, with the helicopter in thecity centre-city centre air transport business. Air Inter is considering an order for 942s. Basic price: Quoted by an unofficial American source at about£250,000 for the 941. The following data apply to the commercial Breguet 942:—Powerplant: Four Turbomeca Turmo HID turboprops of 1,250 s.h.p. each driving Breguet Ratier 14ft 9in reversing propellers.Dimensions: Span, 76ft lin; length 76ft 9Ain: height. 31ft 8in; wing area. 887 sq ft.Weights: Max take-off, 44,0001b; max payload. 12.3501b (13.9001b for the 941 freighter version); max landing weight. 40,0001b; zero-fuelweight. 39,3001b; weight less fuel and payload. 26,9501b. Payload accommodation: Cabin volume. 2,100 cu ft; baggage andfreight volume, 350 cu ft; cabin length. 30ft 8in; max internal width. 9ft 7in; max height. 6ft 6in; max usable floor area. 286 sq ft; dimensionsof largest door, 59in : 7lin; max number of seats. 50 five-abreast at 35in pitch.

(860 st.m.); range B (max fuel), 1,420 n.m. (1,630 st.m.): corres range Bpayload, 4,0001b. Breguet 945 A smaller version of the Breguet 942 is under study,primarily for military use, for operation from 1.000ft hot and high- altitude airstrips. Designated Breguet 945. it would weigh about20,0001b and be powered by two Turbomeca Turmo IIIDs. Payload of about 3,3001b could be carried for more than 900 miles at almost240 m.p.h. BRISTOL Bristol Aircraft Ltd. Fil/on House, Bristol. England(Member of the British Aircraft Corporation). Bristol 170 Freighter The prototype Bristol Freighter first flew onDecember 2, 1945, and was originally offered in two main versions; the Freighter with nose loading doors, and the Wayfarer all-passengerversion without nose doors. Initial 170s had a span" of 98ft and square tips, but the Freighter Mks 21, 21A and 21E and Wayfarer 22A of One of Canadian Pacific Air Lines' six Britannia 314s
