[12] The physical dimensions of most avionics of the period required them to be housed in a large compartment beneath the Trident's flightdeck; the compartment's size was among the factors dictating a distinctive nose undercarriage design, with the nose landing gear offset by 2ft (61cm) to the port side and retracting sideways to stow across the DH.121's longitudinal axis. AA requested greater range than what the aircraft initially had, which meant that the original DH121 design would have fulfilled its requirements almost perfectly. de Havilland DH-121, Airco DH-121) first flew one year before Boeing 727; first instrument landing; first This was the beginning of their phasing out of the Hawker Siddeley Trident 3B. }, Page last modified: The five different In the event, it enabled the Trident to perform the first automatic landing by a civil airliner in scheduled passenger service on 10 June 1965[46] and the first genuinely "blind" landing in scheduled passenger service on 4 November 1966.

The Trident entered a deep stall with the nose going up to a 308-408 attitude. [4] In July 1956, BEA had announced what it called "outline requirements" for a short-haul "second-generation jet airliner", to work alongside its turboprop fleet.

The airliner was initially known as the DH121, conceived by the De Havilland Aircraft Company. The rival Boeing 727 had quickly established a lead over the Trident. It was built during 1962-1978; a total of 117 Tridents were assembled and put into service. Only 117 were built. This was helpful to reduce hydroplaning and give very short landing runs on wet or slippery runways while preserving wheel brake efficiency and keeping wheel brake temperatures low.
