The '''Boeing 777''' is a long-range, wide-body twin-engine airliner built by Boeing Commercial Airplanes. The world's largest twinjet and commonly referred to as the "Triple Seven", it can carry between 283 and 368 passengers in a three-class configuration and has a range from 5,235 to 9,450 [[nautical mile]]s (9,695 to 17,500 km). Distinguishing features of the 777 include the six wheels on each main landing gear, its circular fuselage cross section, the largest diameter turbofan engines of any aircraft, the pronounced "neck" aft of the flight deck, and the blade-like tail cone.

The Boeing 777 is a long-range, wide-body twin-engine airliner built by Boeing Commercial Airplanes. The world's largest twinjet and commonly referred to as the "Triple Seven", it can carry between 283 and 368 passengers in a three-class configuration and has a range from 5,235 to 9,450 nautical miles (9,695 to 17,500 km). Distinguishing features of the 777 include the six wheels on each main landing gear, its circular fuselage cross section, the largest diameter turbofan engines of any aircraft, the pronounced "neck" aft of the flight deck, and the blade-like tail cone.

As of May 2008, 56 customers have placed orders for 1,080 777s. Direct market competitors to the 777 are the Airbus A330-300, A340, and some variants of the A350 XWB, which is currently under development.

Systems

The Boeing 777 is an advanced fly-by-wire aircraft, and the systems are moderately complicated.

Autopilot

777-200 Autopilot

The 777 autopilot can be fully controlled using the 3D cockpit switches. For FG2.4.0 use left and middle mouse buttons to turn any switches left/right. For FG2.5.0 and newer, you can use the mouse scroll wheel on all cockpit knobs.An Autoland system is going to be available as of v2.6.0

You can also use the 777's built-in autopilot tutorial to learn about the different switches.

Autopilot controls, from left to right, top to bottom:

  • A/P - Autopilot engage/disengage button
  • F/D - Flight director (the pink lines that show up on your attitude indicator)
  • A/T ARM (L/R) - Arm/disarm autothrottle for left/right engines. Must be armed to enable autothrottle for the respective engine.
  • CLB CON - Continue climbing using the vertical speed the plane was at, when this setting was first engaged
  • A/T - Autothrottle engage/disengage button. Like the real 777, the autothrottle is independent from the main autopilot, so autothrottle also also works when the autopilot is disabled (Note: this was different for FG2.0 and earlier!).
  • IAS <> MACH - Switch between IAS speed mode and Mach number speed mode
  • IAS window - Set your desired IAS speed or Mach speed here
  • LNAV - Tells the autopilot to follow the Route Manager settings laterally (control the heading)- this has never worked for me, the autopilot just makes meaningless circles/goes north
  • VNAV - Same as LNAV, except vertically (control the altitude)- never tried this setting before
  • FLCH - Flight Level Change, set the altitude and press FLCH to climb or descent to designated flight level.
  • A/P DISENGAGE - Dedicated autopilot disengage button (click twice). It serves as an easy to reach "emergency disengage" button.
  • HDG <> TRK - Switch between heading bug and course track
  • HDG window - Set your desired heading or course track here.
  • HDG select - Engage/disengage heading or course hold mode and maintain SELECTED heading (FG2.5.0 and newer).
  • Bank limits (AUTO/5/25) - Define banking limits for turning, i.e. 5 for gentle turns at cruising altitude, 25 for good maneuverability at lower speeds; auto will be fine in most cases.
  • HOLD - Engage/disengage heading or course hold mode and maintain CURRENT aircraft heading.
  • V/S <> FPA - Switch between Vertical Speed and Flight Path Angle
  • V/S window - Set your desired Vertical Speed or Flight Path Angle
  • VS/FPA - Engage/disengage Vertical Speed/Flight Path Angle hold mode
  • ALTITUDE window - Set your desired altitude here
  • Altitude selection (AUTO/1000) - Switch between automatic incrementing (AUTO) and incrementing by the thousands (1000)- this setting only helps when selecting the altitude via the knobs, this won't apply if using the Autopilot Settings dialog
  • HOLD - Engage/disengage altitude hold mode
  • LOC - Track LOCALIZER, flying by the heading given by the localizer
  • APP - Arm the ILS localizer and glideslope (laterally and vertically). Any current AP mode (HDG and ALTITUDE HOLD) remains active, until the NAV receiver captures the localizer or glideslope.
  • A/P - Engage/disengage autopilot
  • F/D - Flight director

How to use

  • Default mode of when autopilot engage

HDG HOLD mode: Maintain heading when engage. ATT mode: If bank angle exceeds 5deg when engage, keep that bank angle. (there's bug, will be fixed) VS mode: using vs value when engage. If FD mode was engaged, mode is inherited.

  • Mode

Lateral control

HDG HOLD: keep set heading. HDG SEL: follow the heading set on counter. Change value when HDG HOLD or press SEL button when other mode such as VNAV, LOC mode. Once reach to setting heading change to HDG HOLD. LNAV: follow the activated route. LOC: when arming, keep previous mode and then capture LOCALIZER, follow that course.

Vertical control

VS : keep targeted vertical speed to reach selected altitude. FLCH : keep fixed climb thrust or flight idle and control the pitch to maintain speed thus vertical speed varies. VNAV : Follow the FMS target altitude and thrust. ALT HOLD : When you press HOLD button, keep altitude when button pressed. Counter value does not change. Once VS of FLCH reaches targeted altitude, it holds that altitude.
