Simply put, the Boeing Triple Seven is the finest airplane designed by Boeing for perpetuity, that including its relatively trouble free entry into service, which also set be ETOPs standards.
- The Boeing 777–300ER is by far the most successful variant of the Triple Seven family. (All images Boeing from the jet’s fight test campaign.)
It is the first 100% digitally designed aircraft, the first fly-by-wire Boeing jetliner. It is the largest twinjet airliner. The design is maintenance friendly, with a dedicated maintenance access terminal on the large flightdeck, and very flexible cabin design for multiple configurations.
The Boeing 777 has an incredibly fault tolerant design architecture — of its structure, systems and flight control laws, with flight envelope protections available on both the aircraft’s 3 primary flight control computers and 4 actuator control electronics (ACE). The airplane features novel software for normal operations (tail strike protection), and for adverse conditions (thrust asymmetry compensation).
From a pilot’s point of view, the feedback and feel computer inputs be the aircraft into the flight controls gives the pilot a sensation that they’re flying a cable-driven machine, such as the 747–400.
The aircraft and its engines have proved incredibly reliable. The aircraft’s size and capability — particularly that of the 777–300ER — has allowed it to replace traditional 747 operations at significant savings to its airline operators. In all, around 2,000 have been sold — the most popular widebody of the jetage.
