Payload accommodation: Typically 6 seats.Performance: Max speed, 124kt (143 m.p.h.); cruising speed, 113kt (130 m.p.h.); take-off run, 130ft; landing run, 195ft; landing speed, 36kt(41 m.p.h.); min speed, 27kt (31 m.p.h.); rate of climb, 835ft/min, or 235ft/min on one engine; max range, 540 n.m. (620 st.m.). An-16 Projected as a stretched development of the An-lOA, this typedoes not seem to have materialized. An-24 The first reference to this new feederliner appeared inFlight of June 17. Y. Loginov, head of Aeroflot, was reported as having stated that the type was intended to replace piston-engined aircraft ondomestic routes. The report ran: "It will carry 32 passengers in the standard version and 40 in a high-density configuration at a cruisingspeed of up to 326 m.p.h. Range is said to be 900-1,240 miles, and take-off distance 500m." When a new picture was published in ourissue of August 19 it was stated that take-off run would not exceed 1,000ft. Important additional information, particularly on construction,appeared in our issue of November 4. Powerplant: Two Ivchenko turboprops of 2,000 s.h.p.

AVIATION TRADERS Aviation Traders (Engineering) Ltd, 21 Wigmore Street, London Wl. ATL-98 Carvair This is a modification of the DC-4, 10 of whichare to be produced for Channel Air Bridge, a British United Airways Company. This operator has wanted an aircraft with four engines,capacity for five cars and 25 passengers, long range, cheaper operating costs than the Bristol Freighter, and cheap to buy new. The answer wasa conversion of the DC-4 involving a new nose and a new fin. It will be ready for service in the late summer 1961 on the long-haul vehicle ferryroutes for which permission has now been granted. The first flight is expected in February or March next year.

Avro 688 Super Trader Developed from the Avro Tudor 4B, theSuper Trader proved a successful passenger-cargo transport in Air Charter service but is now superseded and none is flying. Flight references: February 26, 1954, and November 20, 1959(technical data). Avro 748 Announced on January 9, 1959, the 748 is the latest Britishentry in the DC-3 replacement market. Like its main competitors the Handley Page Herald and the Fokker Friendship, it is powered by twoRolls-Royce Dart turboprops. The RDa.6-powered version is standard but a Series 2 aircraft, powered by RDa.7s, is also available particularlyfor operation in hot climates and at high altitudes. The prototype first flew on June 24. An initial production batch of twelve aircraft is wellunder way and plans have recently been announced to increase produc- tion to 60 aircraft. Orders have been received from two British inde-pendents, Skyways (3) and BKS (5); the Indian Government is building the 748 under licence for the Indian Air Force and three Avro 748Series 2s have been ordered by Aden Airways.
