Boeing Triple Seven
Widebody passenger transport jets made their introduction in the 1960s early 70s in the form of the Boeing 747, McDonnell Douglas DC-10 and the Lockheed L1011 Tristar. Preparing for the retirement of the Boeing 727 faithful workhorse, Boeing in 1978 announced the 757 narrow body, as well as the 767 wide-body which was to go up against the Airbus A330. Boeing also was kicking around a Boeing 777 jet idea which was a tri-jet, to go up against the DC-10 and L1011.
Nov 02, 2020 Normally referred to as the “triple seven,” it has become a firm favorite with airlines and pilots alike. The airlines love the way its performance affects their balance sheets and pilots love it for its simplicity and versatility. Here is the definitive guide on all you need to know about “The Triple.” Table of contents show. The Boeing 777 'Triple Seven' is the largest twin-engined airliner in the world and it is intended to fly medium to ultra-long distances with 300 to 400 passengers. In the late eighties Boeing identified a gap in its product range between the 767 and the 747. I have never seen such a fast Boeing 777 takeoff. 15 seconds after the engines spooled up the Triple Seven was already airborne. At the beginning of the vide.

Throughout the 1970s, the Boeing Company operated the mammoth 747 four-engined, 'wide-body' long-range jet airliner. In 1978, a move was enacted to supplement the 747 with the 'narrow-body' 757 series, the wide-body 767 series and the Trijet 777, a triple-engine aircraft - a design proving popular at the time.
ETOPS
The Boeing 757 and 767 models were well accepted by the market. The timing was fortuitous, as in the early 1980s new regulations were introduced governing the operations of twin-engine aircraft on transoceanic routes. ETOPS, (Extended-range Twin-engine Operational Performance Standards), allowed certificated aircraft to fly up to three hours (ETOPS180) from the nearest available alternative airfield. The Boeing 767 began to be used under this regulation on oceanic routes that did not require the seating capacity of the larger widebodies.
Filling the Gap
There was still a gap in Boeing’s stable of aircraft between the Boeing 767 and the Boeing 747 which needed to be filled.
McDonnell Douglas announced the MD11 to replace the ageing DC10. Airbus had the Airbus A330 and A340. In 1986 Boeing floated ideas to create an enlarged Boeing 767. Called the Boeing 767-X, the design had a longer fuselage, larger wings with winglets and a wider cabin. The response from airlines was not encouraging at all. The market called for an even wider fuselage, flexible cabin layouts and better fuel economy than could be delivered by any Boeing 767 variant.
A New Design
In 1988 Boeing reacting to the market, acknowledged that a brand new design was called for and the Boeing 777 idea was born.
In a departure from the norm, Boeing gathered 8 leading airlines to become part of the design group. The Working Together Group, as it was called, was made up of All Nippon Airways, American Airlines, British Airways, Cathay Pacific Airways, Delta Air Lines, Japan Airlines, QANTAS, and United Airlines. Rather than presenting the market with what Boeing perceived as their idea of what was required, customers had direct input.

| January 1993 | Boeing designers and around 240 airline teams gathered at Everett to address around 1,500 design issues. Modifications were made. Cathay Pacific influenced an increase of the fuselage diameter, All Nippon Airways demanded lengthening of the base model fuselage, whilst British Airways asked for more interior flexibility and increased weight options. |
| 4 January 1994 | Assembly begins on the first aircraft. |
