- Boeing 777-200 Preflight Inspection Part 1 | APU Start
Prior to each flight of the day a preflight inspection of the plane is required to determine the aircraft readiness to fly. During the preflight inspection the aircraft systems are tested and visual inspections are conducted.
During this part I arrive on the plane to power up the APU and begin the preflight. First thing I do is to go to the EE (electronic equipment) bay to connect the main battery. We disconnect the main battery during parking to prevent it from discharging. After the battery is connected I start the APU to provide electrical power and pneumatic pressure. As the APU reaches 100% rpm the APU generator automatically comes online and begins to supply electricity to the aircraft. When the aircraft receives electric power the avionics systems power on and begin to run their BITE (built in test equipment) to verify that they are operating normally. If there is a fault detected during the BITE then it will be displayed for me to see and I can determine what corrective action may be required.
Great video! Being an engineer and a pilot of the Boeing 777 is something more than just a job it’s like a destiny. Boeing 777 line is the most technological plane and it made massive impact on aviation history. On 9th November 2005 Boeing 777-200LR made a historical flight from Hong Kong to London Heathrow which is considered as longest distance travelled flight (11664 miles) ever. Looking back on what success aviation has achieved from Wright brothers flight to Boeing 777 is great. While observing the avionics compartment and realizing what amount of programming, electrical engineering has been contributed and invested to this fantastic plane makes me to do a big regards and bow to Boeing engineers. I hope that 777X program would even double the original success of 777 line. As the new Boeing 777X would be powered by the biggest commercial aviation engines GE9X I hope that this plane can improve the record of 9th November 2005 flight. I am very proud for the USA and Boeing that they engineered such outstanding plane. Boeing 777 is the rare example when the thing can combine perfect engineering and gorgeous design. I really think that it’s something special about to work so professionaly and close with this plane.
Please do more videos, there amazzing
+AviationVideos Thanks
@@BigIronTV i want to learn more abou your 777. It is amazing Keep it up!
Exactly what I was looking for. Thank you for explaining it so well. Cheers! 👍🏽
What a beautiful aircraft!
Thanks for the tail number. I was like, "I've not seen an accessibile EE bay on a normal passenger model outside of the factory."
VIP model. Makes sense. Doesn't look like it has officially flown out of Saudi Arabia since late 2017 a few months after the.... incident.
Definitely one of the more special 777's to have flown.
great video man!! bravo
Absolutely love your videos. I am about to start airframe 2 can't wait to finish my a & p. keep up the excellent videos.
+Zavier Lucaino Cool. Thanks for watching.
Thanks this helps greatly with flight simulator.
great thanks bro
FRICKEN COOL MAN!!
+SSR KNIVES AND GUNS! Glad you liked it.
Cool video... I think I'll subscribe
Great video.. Loving the pre trips lots of great stuff.. For us land dwellers lol
+Shiny Knife Thanks. Even the pilots that fly with me have never seen lots of this stuff. Because at the airlines they show up and sit down and fly. With us they get more opportunity to see the full operation at all stages.
Exelle video: very detailed at a very good speed, for people like me.
I thought you just press loads of buttons and off you go. You have to climb inside the AV bay and rummage around in the dark before even getting started. I never thought so much preparation is required. Fascinating stuff👍
You’re so lucky to fly this beast BBJ
it would be cool to like do a solo flight on those types of planes it would feel a bit scary since theres just 1 pilot but yeah cool video showing the electronics of the plane and doing preflight procedures of a Boeing 777-200
Really nice!
+Ride84XL Thanks Glad you enjoyed helping me do the preflight.

So this green tank is main battery. Wow. I thought it is much bigger.
I thought the avionics and other computerized equipment required continuous DC for memory, time, etc. I guess everything is FGA (Floating Gate Arrays).
thanks for sharing!
+Ahmad Adelgary Hi Ahmad, thanks for watching. What did you think about the two camera format? It is something new that I am trying once in awhile on videos.
+BigIronTV it's a great idea but i would suggest using this format to cover two connected actions like the APU switch while it's being turned on and what will happen outside :)
That is a good idea. Like show pressing the button etc in the flight deck and see the apu inlet door open and hear it start to spin?
+BigIronTV exactly!
Ahmad Adelgary Ok. I will do some more of that format too. Thanks.
Beautiful cockpit! Hope Boeing keeps it that way for the 777X...
the trend in new design seems to be to remove the circuit breaker panels because they can be reset electronically using the multi function display.
+BigIronTV So, do you think it might be similar to the 787's cockpit? Because I think there are too many screens... Still a beautiful aircraft!
Is disconnecting the main battery (as part of returning the aircraft to "cold-and-dark" state) on every other jet a normal procedure (to protect the battery from unwanted discharge)? I've never come across/heard of this being done even though your reason for doing so is perfectly understandable (I do the same on my old 2003 Toyota Corrolla sedan).
lol, parasitic draw really does kill corollas
Thank you for these amazing videos :) May I ask a question: why is the fuel-shutoff battery in the cockpit? Is it very common for it to be disconnected for maintainable reasons, and will there be a need to access the battery inflight? Thanks :)
Hi, I don't know the reason for its location. There is normally no reason for it to be disconnected on a normal Boeing 777 because they are flying very regularly in an airline. In a private jet situation we do not fly as often and the battery will discharge over a few days with the plane not operating. So that is the reason this plane gets it disconnected when parking.
BigIronTV Thank you! Have a great day :)
Why are interior systems running from hot battery bus and not ground service AC bus like it used to be on "normal" 777? Couldn't they just install switch to shed those loads to preserve battery charge?
Emergency lights has their own battery, right? Is there any way to check state of charge of emerg lights battery?
Is it possible to power ECAM from battery using standby power switch to observe APU spool up on STAT page?
What is CRD panel on the center pedestal for?
Requesting: APU maintenance page display and everything related with SATCOM.

So may high quality posts on aviation channels here on YT. I didn't know there were comment sections like this on YT! It's like being on a professional's forum!
Wondering what the reason is for a Mid East Jet aircraft having a US registration is.
Is that Dammam Airport?
Whats your reasoning on leaving the L/R Packs and APU bleed off ?
+Clarke Ramsey Hi. Very observant. I closed the ram air inlet doors during parking to keep the birds from building nests in inlet to the packs. I don't show it but when I do open the the ram air inlet doors and turn on the packs pigeon nest materials fly out of both pack exhausts. I will get to the packs a bit later in the preflight series. I am currently editing the footage. It will be a couple more parts yet. Hope to get them all posted over the weekend.
+BigIronTV Hello. Thanks. That's what I was thinking. Thanks for your videos!
Clarke Ramsey Glad you enjoy them.
BBJ777-200ER?
why you dont have to test the fire protection system of the APU before starting it?
the system with self check it first and if it finds a fault it will not start the start sequence.
@@boeingt7236 thanks for the information
do we know who the owner is?
Saudi Royal family.
WHERE IS THE TAIL NUMBER???
One the tail. lol N777AS
There is only one thing you did wrong.The next time try slowly to open S/V of the oxygen cylinder!
