The Boeing 777-200 (772A) was the initial A-market model of the Boeing 777. The first customer delivery was to United Airlines in May 1995. It is available with a maximum take-off weight (MTOW) from 505,000 to 545,000 pounds (229 to 247 tonnes) and range capability between 3,780 and 5,235 nautical miles (7,000 to 9,695 km).
The direct equivalent from Airbus is the Airbus A330-300. A total of 88 -200s have been delivered to ten different customers as of July 2008.
See Boeing 777#Aircraft Help for the main article about this subject.
Important notice: as of FlightGear 2.4.0, the 777 has tiller steering, just like the real aircraft where the pedals only turn the nose wheel by a few degrees - to achieve optimal precision during takeoffs and landings. Use the tiller (777-200ER > Tiller Steering) dialog to steer during taxiing.
- You can also connect a separate joystick axis to the tiller control - just like in the real aircraft, where there is a separate control wheel.
- Finally, you can also disable the separate tiller control and revert to the unrealistic behaviour of using pedals only to completely control the nose wheel (see 777-200ER > Tiller Steering dialog).
- Go to Equipment > Fuel and Payload and set your fuel amounts and make sure your tanks are selected
- Right-click twice to get into the move view mode and look at the overhead panel then click all the electrical buttons until they are all lit up
- Hold the 's' button for 10 seconds or until the engines are running at idle.
See Boeing 777#Autopilot for the main article about this subject.
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.
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.
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.
- Autopilot using LNAV/VNAV e.g. From KATL to KMIA.
- Location->Position Aircraft On Ground. Enter KATL to Airport and select Runway 09L then press Go To Airport.
- Press BATTERY button on OHP then rotate APU knob to START. This switch automatically spring back to ON. Press APU GEN button if its not on.
- Press L BUS TIE, R BUS TIE breaker to AUTO and L and R engine generator to ON.
- Adjust backlight of Overhead panel and Instrument using OVHD and PNL/FLOOD outer knob.
- Open Autopilot->Route Manager. KATL is already entered at Departure: so enter KMIA to Arrival: and select Rwy: 27.
- Note the distance to KMIA-27(27) is 518.0nm.
- Click arrow of Approach: then reselect DEFAULT. Approach waypoints are added.
- Click arrow of SID: then select DEFAULT. Departure waypoints are added. Make sure 1st approach way point does not have altitude restriction. If it has add the fix before that.
- Equipment->Map. Check and modify route not to have sharp angle way point.
- Equipment->Fuel and Payload. Set Total fuel wight to noted mileage 518 * 45 + 10000 = 33500lbs then press Balance button. Check Gross Weight not exceed Maximum Take Off wight then Press Close.
- Set cruise altitude in Route Manager to 41000 feet. Be careful that if you have heavy weight you can not reach high altitude and of cause if you don't have enough distance you can not reach that cruise altitude ether and that will cause VNAV not available.
- Now you can save this route for later use.
- Press Activate button then Close Route Manager.
- You may close Map or keep it open with Transparent to check course.
- Set cruise Alt to MCP Altitude counter to 41000. Left click on AUTO to 1000 then press and hold the left button or scroll center button on left lower of knob to adjust.

- Wait until gear up, then adjust pitch trim to maintain F/D pitch bar center.
- Flap up according to the speed.
- Once ship stable without any force apply to control, then press AP.
- Turn on the cabin light.
- Now ship follows LNAV course and climb to cruise altitude by VNAV.
- Around 10000ft, turn off the landing light.
- When you pass the FL14(Japan) or FL18(USA)(You can change in Autopilot Control menu), press STD button to set STD to QNH.
- Once reach to the cruise altitude and before you reach the TOD(Top Of Descent) (Green circle on route ), set Altitude counter to 2500 (Arrival airport AGL 2500, this time KMIA elevation is 8ft thus 2500ft). If you get “Reset Altitude” warning message you may not use VNAV any more so please use normal Autopilot such as V/S or FLCH mode till approach.
- When ship reaches TOD, automatically start to descent with 0.78M or 280Knot.
- When pass the transition altitude (FL14) press STD button and adjust QNH to KMIA pressure.
