Boeing B777-300ER APU startup.

[@vedymin1]

Its cool to see the 777 load shedding and not lighting everything up immediately on battery push 🐸

[@dennisvijverbergbrakesrele6098]

@@vedymin1 it really doesn’t do much on batteries, although if you switch on the standby power more will come on with batteries only. But this is not needed when starting the APU

You need either apu or gpu to get the full stuff.

[@noel0004]

Love these videos! I got lucky and could visit the cockpit of a 777-300ER and sit in the right hand seat. Such a beautiful cockpit, and aircraft!

[@dennisvijverbergbrakesrele6098]

Glad you enjoyed it!

[@G-Nema]

Wow nice start, if i grow up i wanna be an airline Pilot and fly a b777-300ER, its my dream plane

[@MGGAMERZ428]

Same bro ❤

[@SYDAirlineEnthusiast]

Pilots usually turn on the ground power instead as apu burns fuel, and this only gets turned on a few minutes before engine start as the apu is needed for the engines to start without having to use an air starter.

[@iVTECInside]

No where to see APU status as it starts? Surprised how long it took for the flight displays to turn on.

[@dennisvijverbergbrakesrele6098]

You can turn on the standby power to start up AIMS but that would take about 10 minutes, and because we do not want to drain the battery, it is normally not done. If on external power you can see the start up on the status page.

[@iVTECInside]

@@dennisvijverbergbrakesrele6098 Makes sense. in the event of a fault how would you know in this scenario? Other than the APU not coming online within x number of seconds?

[@dennisvijverbergbrakesrele6098]

When APU fails to start or has an auto shutdown, you would need to connect a GPU to troubleshoot the problem.

[@Advocatz]

4:00 what is that noise, sounds like a mic test or something? I hear that on my flight sim's 777 as well on startup, and I thought it's just to simulate a flight attendant's mic check

[@dennisvijverbergbrakesrele6098]

I think that sound comes from startup of the audio management system, not 100% sure though

[@starpawsy]

Bit of a bummer that there is no APU instrumnetation until AFTER the APU is running :O

[@dennisvijverbergbrakesrele6098]

Only if started on external pwr you would see the indications.

[@timduggan1461]

Yeah, my first thought too...but since I never "typed" on the B-777 I based your comment on my experience with other Boeings and Douglas. The fire warnings were/are powered by the Battery Bus, but not the squibs if I recall correctly (retired now, need to check my manuals).

[@davebondanza8489]

Great to see but I gotta say I've seen a bank of vacuum tubes get operational faster than this lol.

[@dennisvijverbergbrakesrele6098]

Indeed, the AIMS is a bit slow starting up with all the software is needs load before it is operational.

[@softwarephil1709]

No feedback showing the APU is starting?

[@dennisvijverbergbrakesrele6098]

Nope, just the sound of a starting APU on the background, but if it doesn’t start on the battery the first time we will need an external power to see what is wrong with the APU.

[@dankk2754]

Mooie kist die 777-300

When two engine on and trun off apu why electry does work? What is main electry?

[@bratanchk]

Engines have generators

[@komrad1983]

Didn't I fly with you in PANAM academy on 777 full motion in MIA?

[@ewanman6303]

Great video!! Appreciate the effort. Other than Brake Source and L Main/ R Main Generator Off lights will any other indicator, display or instrument power on if it’s just on battery?

[@dennisvijverbergbrakesrele6098]

Thanks. You can turn on the standby pwr but that takes some time. Normally you just start up the APU like this.

[@carlos23161]

I thought the sequence, after APU power was established, was: APU bleed air-AUTO Left & right packs-AUTO ADIRU-On Hydraulic Primary switches, all 4, pushed “ON” Fire test. I’m still learning though. I’m going from a 747 into a 777. Maybe leaving APU bleed air switches & pack switches on after shutdown, is normal too. IDK

[@dennisvijverbergbrakesrele6098]

Hi, with the B777 pack switches are when shutting down APU switched off. APU bleed switch stays in AUTO. I normally don’t startup ADIRU if I don’t need it, flight crew then shuts it down and restart it again. Also don’t switch on hydraulics, flight crew only switches hydraulics on just before departure. Fire test is done when electrical pwr available after start up APU with the batteries. If external pwr is connected you can do it before.

[@thongteevee]

Do you know what is the HYD PRESS in the STAT page is? It says 90 in the video, but I search online and it said the system pressure is 3000psi. Are there any differences?

[@dennisvijverbergbrakesrele6098]

As there are no hydraulic pumps on there is no system pressure. Brake pressure is the only one available and that comes thanks to from a accumulator.

[@thongteevee]

@@dennisvijverbergbrakesrele6098 So after the engine is turned on, it will show ~3000, isn't it? Thanks for you help

[@john.enospahitamos3596]

Can you start the apu without turning on the battery?

[@dennisvijverbergbrakesrele6098]

If you have no pwr at all on the aircraft APU will not start. The APUC at least needs battery pwr to control the start up of the APU.

[@DenDanskeKarpe]

Please do one with the 777-200ER because i need it :)

[@dennisvijverbergbrakesrele6098]

🧐

[@matthews3432]

I have been on JJS. Has a bad Air conditioner though.

[@dennisvijverbergbrakesrele6098]

Maybe the air came from the outside connection and not from the the airco packs

[@matthews3432]

After we pushed from the gate and the JJS was on it’s own power there still wasn’t good AC. I asked the Turkish airlines flight attendants and there was no solution. Was brutal for 12 hours.

Would actually like to see what you're doing and not of the random panel near it.

Something for a new video, thanks

[@timduggan1461]

Informative. I flew almost everything at my airline except the B-777 and B-747. (Retired now, but still have a memory). I am gathering that you're technical/maintenance, not flight crew?

[@dennisvijverbergbrakesrele6098]

Yes, a aircraft maintenance technician

[@cipherjoe9]

Those screens need some cleaning omg

[@jackmidd123]

It bothers me that it says “tiller” like the flight crew are useless. Imagine a car said “steering wheel”

[@dennisvijverbergbrakesrele6098]

Maybe because they can mistake the handle for opening the window for the steering tiller 😬. Sometimes it just the way they do things.

[@jackmidd123]

@@dennisvijverbergbrakesrele6098 why does it not say “throttle” Incase they mistake it for an arm-rest?

[@timduggan1461]

Airplanes are notorious for labeling everything. Simple.

[@timduggan1461]

​​@@jackmidd123 If you look closely you can see little armrests, or "wristrests", just aft of the FMCs. The B-737, B-757 and B-767 didn't have such niceties when I flew them. "Oh! Humanity!". LOL.

[@SYDAirlineEnthusiast]

It’s cause each panel is different, and there are too many instruments to memorize. 777 Pilots don’t just fly a 777.

You did Not make a Fire Test

[@dennisvijverbergbrakesrele6098]

Yes I did, when you start APU with the battery only, you do the fire test after the AIMS (Airplane Information Management System) has fully started up. Check the end of the video.

[@tfc5389]

How is he going to make a fire test without gpu or apu. If I did the batteries would drain.

[@shaxbozabulov-sn7dh]

[@kurthunter2427]

APU fire test before starting…..nah! who needs that

[@dennisvijverbergbrakesrele6098]

Fire test doesn’t work when starting with batteries, as AIMS isn’t powered you can’t test the system, you can do it after pwr up. But don’t worry the APUC is very capable in controlling and monitoring the startup and will take action when a fire is detected.
