I will set our position on the FMC (flight management computer) using the data from our
GPS (global positioning system).
Select position initialization and the prompt displays indicating position data is required
in those boxes.
Move to the previous page to display the GPS position.
By using the LSK (line select key) I am able to select the GPS data and move it to the
clipboard at the bottom of the screen.
Go back to position initialization page and press the LSK at the position input and the
GPS data from the bottom of the page is moved into position.
Now our navigation systems are aligned and know their position in the world.
We will look at the overhead panel and make sure it is setup for the flight.
This is the air conditioning panel.
Equipment cooling, recirculation fans, trim air valves, temperature selectors for cabin
and flight deck.
It is set a bit cool right now.
These are the pack switches that turn the packs on and off.
These are the trim air switches.
Bleed isolation switches.
When we are in normal flight you feed from the right engine to the right pack and trim
and from the left engine to the left pack and trim.
If a problem occurs and causes one side to loose pneumatic pressure then the isolation
valves will automatically open to allow pneumatic pressure from the operating engine to supply
air to both the left and right systems.
This is the pressurization panel.
Outflow valve switches.
Manual landing altitude select knob if required.
Right windshield wiper.
The windshield is too dirty to turn it on for demonstration.
These are runway lights, red beacon lights for belly and crown, navigation lights on
the wing tips red, green, and white.
Logo lights that shine from the top of the horizontal stabilizer to the vertical to illuminate
the tail.
These are wing lights that shine on the engine inlets.
Strobes, runway turnoff, taxi, landing lights.
Flight deck instrument lights dimmers.
Anti-ice panel normally operated in auto position.
This microphone is for recording voice and sounds in the flight deck onto the Cockpit
Voice Recorder to be used in the event of an accident investigation.
It is on a loop and records that last few minutes.
Passenger signs put them in auto then at specific configurations like gear down and flaps down
they will illuminate the fasten seatbelt signs.
Fuel panel.
We are supplying fuel from the left main using the forward fuel pump to the APU.
I am going to display the fuel system status on
the monitor.
The green box is the fuel pump and the green line indicates where the fuel is flowing to.
When we have fuel in the center tank it will feed first because the center pumps put out
a high pressure than the main tank pumps.
This is done for weight and balance.
Fuel jettison panel.
Lift these two protected switches to activate the fuel dump through the
fuel dump nozzles that I pointed out earlier in the preflight on the outboard trailing
edge of each wing.
This is the engine start panel.
Turn this switch to the start position to begin the engine start sequence.
If we are in bad weather they will put the switch into continuous so the ignitors fire
and keep the engine from having a flameout.
This is the cargo fire control panel.
Select the target zone then lift up the cover and press the switch to discharge the fire
bottle into that area.
Flight information data and pre-recorded passenger briefings.
This panel is unique to only this airplane.
We have an interior door monitoring system.
Electrical controls for our passenger inflight entertainment and passenger emergency oxygen.
Service interphone switch for maintenance functions.
Ram air turbine.
Lift the cover and press the button and the ram air turbine will drop out and begin to
generate electricity and hydraulic power from the air flow passed using a windmill type
of head.
Our hydraulic panel.
on the right engine we have one electric pump and one gear driven pump turned by the engine
gearbox.
Center system we have two electric pumps and two pumps that are driven by pneumatic pressure
taken from the compressor section of each engine or APU.
Left engine same as the right.
Our cabin smoke detection system.
Has 14 zones.
If smoke is detected then it will display a warning and also indicate the reporting
zone so we can go and check it out.
The ARIRU (air data inertial reference unit) part of our navigation system.
Thrust asymmetry computer.
Electrical panel with main battery switch, APU on/off switch, APU generator switch, bus
tie switches, external power switches, backup generator switches.
Left windshield wiper switch.
