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!
Glad you enjoyed it!
Bit of a bummer that there is no APU instrumnetation until AFTER the APU is running :O
Only if started on external pwr you would see the indications.
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).
Amazing ❤
Great to see but I gotta say I've seen a bank of vacuum tubes get operational faster than this lol.
Indeed, the AIMS is a bit slow starting up with all the software is needs load before it is operational.
Mooie kist die 777-300
Yes it is
😍😍
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?
Thanks.
You can turn on the standby pwr but that takes some time. Normally you just start up the APU like this.
Those screens need some cleaning omg
Didn't I fly with you in PANAM academy on 777 full motion in MIA?
No where to see APU status as it starts? Surprised how long it took for the flight displays to turn on.
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.
@@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?
When APU fails to start or has an auto shutdown, you would need to connect a GPU to troubleshoot the problem.
747 next please.
It’s there
When two engine on and trun off apu why electry does work? What is main electry?
Engines have generators
No feedback showing the APU is starting?
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.
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?
Yes, a aircraft maintenance technician
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
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.
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?
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.
@@dennisvijverbergbrakesrele6098 So after the engine is turned on, it will show ~3000, isn't it?
Thanks for you help
Can you start the apu without turning on the battery?
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.
Thy nin uçağını bu arkadaş hangi sıfatla girip kurcalıyabiliyor ?
If correct out of google translate, my response would be: because I was hired to that by THY
++++
Would actually like to see what you're doing and not of the random panel near it.
Something for a new video, thanks
It bothers me that it says “tiller” like the flight crew are useless. Imagine a car said “steering wheel”
Maybe because they can mistake the handle for opening the window for the steering tiller 😬.
Sometimes it just the way they do things.
@@dennisvijverbergbrakesrele6098 why does it not say “throttle” Incase they mistake it for an arm-rest?
Airplanes are notorious for labeling everything. Simple.
@@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.
APU fire test before starting…..nah! who needs that
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.
You did Not make a Fire Test
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.
How is he going to make a fire test without gpu or apu. If I did the batteries would drain.
