The Boeing 777 is a long-range, wide-body twin-engine jet airliner manufactured by Boeing Commercial Airplanes. It is the world's largest twinjet and is commonly referred to as the "Triple Seven". The stretched 777-300 (773) was designed as an A-market replacement for 747-100s and 747-200s. The -300 features a 33.3 ft (10.1 m) fuselage stretch over the baseline -200, allowing seating for up to 550 passengers in a single class high-density configuration. The 777-300ER ("ER" for Extended Range) is the B-market version of the -300. It features raked and extended wingtips, a new main landing gear, reinforced nose gear, and extra fuel tanks.

Start Procedure

0. remember to
a) set the correct QNH (pressure) when below transition level
b) set the fuel to a proper level in each tank (so you dont mess with the sliders when airborne)
c) you can use ctrl+c to reveal all usable buttons and knobs

1. prepare systems
a) turn on the battery, taxi lights and panel lights if you need it (button is placed) to tle left, left from the BCN light button.
b) turn the APU knob clockwise (the knob next to the APU GEN), wait 1min for it to start-up
b1) set APU knob to the middle position
c) turn on all 4 hydraulic pumps/valves. 2 in the center are for the flaps and spoilers (both
pumps MUST be enabled), the same with the other two, they are for landing gear. the buttons are between electrical and fuel part of the panel.

2. prepare engines
a) start fuel pumps. there are 6: 2 for each tank. to enable fuel flow from a tank, you have to enable BOTH (just like with the hydraulics) pumps.
b) enable the engine starters (you can turn on both one after another, but thats not really realistic)
c) after N1 reach ~45, engine should be running on its own, self sustaining, fuel cutoff valves open automatically. eicas shows up a message that L(R) ENG STARTER is on.
d) turn on both engine generators
e), turn off APU (knob position 1) and BAT

3. jettisonning fuel
a) just press the JETTISON ARM button, its hidden behind some knob in the right part of the OH panel, go to 0. a) if you cant find it
b) monitor the fuel levels, press the button again to stop the process. (jettisonning will automatically stop when theres ~1000 gallons in each tank)
c) fuel flow is 30 gallons per second.

4. using the crossfeed (XFEED VALVE/PUMP)
a) enable FWD xfeed pump and AFTER IT enable AFT pump. if you mess this, it wont work and you will have to repeat.
b) watch the fuel indicators on the eicas as the fuel level gets equalized in both tanks, left and right.
c) fuel flow is set to 4 gallons per second.

5. using the bank limit knob
a) position 0 activates the automatic bank limiter (limit based on airspeed)
b) any other position sets a constant bank limit, 5, 10, 15, 20, 25
c) for speeds below V2+15 use 15 degree bank limit
