'''Rotate the APU switch to START''' (click twice). The switch will rotate back to ON and the APU will be started (this will take several seconds). As soon as AVAIL is displayed on the APU GEN witches, set them to ON (once again this will take a while). The APU has now taken over the job of power source from the battery, which we must leave switched on! | '''Rotate the APU switch to START''' (click twice).

Press the INIT REF button on one of the CDUs on the pedestal. Then click the button next to TAKEOFF. Type the flap setting you will be using on takeoff, making use of the digits pad, then press the button next to the flap setting (upper left side button). Flap 20 is the standard flaps setting for takeoffs in the 747. You can also use flaps 10, but it will take longer for you to get airborne. '''Write down or remember your V2 speed''', as we will need this number in a moment. | |||
'''Turn the F/D (Flight Director) ON.''' When the autopilot is on, the Flight Director is what controls where your plane goes. When the autopilot is off, the F/D will give us visual cues as to climb pitch and bank angle to keep the aircraft flying safely. | |||
Enter V2 speed into the IAS/MACH indicator on the dashboard. You can adjust the autopilot indicator numbers by clicking the appropriate knob with your left mouse button (to increase value) or middle/3rd mouse button (to lower value). <font color="red">'''Currently you need to use the Autopilot > Autopilot Settings menu dialog!'''</font> My FMC reported a V2 speed of 144 knots, so I have entered 144 into the IAS/MACH indicator. Immediately after takeoff, you will use aircraft pitch to maintain this speed. | |||
'''Arm LNAV and VNAV''' by clicking on their respective buttons on the MCP. LNAV will control the lateral movement of the aircraft (i.e., follow your flight plan direction) and VNAV will control the vertical movement of the aircraft (get you to your cruise altitude and back down efficiently and safely). At this time we are only arming these autopilot functions. They will not actually control the aircraft until the autopilot is engages after we are airborne. | |||
'''Set HDG to the heading of the takeoff runway.''' | |||
'''Set ALT to 10000.''' You would typically set this to your initial cleared altitude as given by ATC. 10,000 feet will work nicely for most flights. | |||
'''Ensure the autopilot DISENGAGE bar is UP.''' | |||
'''Ensure that fuel control switches are set at CUTOFF''' (knobs pulled out and down). This will ensure that fuel will not flow to the engines | '''Ensure that fuel control switches are set at CUTOFF''' (knobs pulled out and down). This will ensure that fuel will not flow to the engines | ||
'''Set AUTOBRAKES to RTO.''' This will initiate full braking if something goes wrong during your takeoff roll and you reject (decide to end) the takeoff. Rejected Take Off braking WILL stop the plane VERY quickly if things go badly before you takeoff. | |||
'''Ensure that the SEATBELTS selector is set to AUTO.''' AUTO will turn off the SEATBELT indicator when you are above 10,000 feet. | |||
===Pushback and start=== | |||
'''Ensure all throttles are at idle.''' | |||
'''Turn ON continuous ignition.''' This will send a continual spark to the engines which will ignite the fuel when it is introduced. | |||
'''Pull the Engine Start Selector for Engine 4.''' | |||
Watch the N2% RPM increase in the EICAS display. Bleed air from the APU is being 'blown' across the engine and is beginning to turn the turbines. '''When the N2% RPM indicator on the EICAS reaches around 14%, switch the Fuel Control Switch for Engine 4 to RUN.''' The engine should start up and then idle back. | |||
