@@nefarioulyte9996 nope just a complex system of check valves, sequence valves and actuators. No computers..purely hydromechanical system excellently engineered
@@justing42The prox switches only drive the indicator lights and EICAS messages.

The whole process is all sequenced with mechanically operated hydraulic valves.
In normal ops it's quicker. It's been a long time since I flew the 76 but it had an ADP- Air Demand Pump. It used a bleed air pump to speed up, gear retraction. Many flyable malfunctions require performance corrections, most of them small. For example if a flap track fairing (the canoe looking thing at the trailing edge of the wing) was damaged and removed you would use numbers that were about 500 lbs heavier for takeoff and 1000 lbs for cruise. The ADP penalty for takeoff was huge- 40,000lbs. A 76 without the ADP performed like a 76 40K lbs heavier. If you lost an engine at liftoff and the gear took twice as long to retract that matters! Cheers
@Trebuchet48 Apparently… though I’m not sure.. it was to correct the fact that the gear could not fit in the wells as originally designed. The 767 was the last Boeing plane to be designed without AutoCAD and 3D models to verify it (CAITA).
Now we need a video of the little door on the top side of the 767 wing that opens for a second to allow part of the gear mechanism to cycle through the opening. I asked the captain about it when I observed it on a flight in 2001. He knew nothing about it. Was I hallucinating?
You’re very observant, and correct. There is a door on top of the wing, literally called a “Pop-Up Door”, that exists only to rise slightly and allow clearance for the trunnion crank and actuator during gear extension and retraction. I’m not surprised the Captain would know nothing about that. They can’t see it from the cockpit, nor on a walkaround. I have rigged those doors.
In flight with engine driven hydraulic pumps the gear moves faster. The auxiliary and/or ground powered hydraulic pumps provide lower flow. (Some ground powered units can have pressure and flow adjusted, we typically keep pressure at system operating pressure but slow the flow for better observation and inspection checks)
It's just water, there is a spot on top the side struts that water doesn't drain from. This happens after the plane has been through wash. I work on 767's everyday.
I’m not sure if this applies to the 767 (I can’t see why it wouldn’t) but the Cessna 150s I fly all have red coloured hydraulic fluid. Easy to spot if something’s wrong.
@Mr. Person airliners use skydrol for hydraulic fluid. It's mostly clear with a bit of a purple tint. Your airplane uses 5606 which is red in the nose strut.
0:30 i think that's the problem, either the right landing gear closes too late rather than the left one or the left one enters too quickly. basically the two gears are out of sync. that's why the plane was checked and repaired. so that both wheels come in and out simultaneously.
There is a certain second time interval by the time the gear extends and retracts. As long as from the start the doors open, gear is down and locked, retracted and gear doors closed at the allowed time, it is acceptable. The gear needed r&r due to time.
The gear retraction is not synchronized. As long as both gear go up and down, that’s good enough. There is a check for timing, but it requires a hydraulic source with enough flow (35 gallons per minute if I recall correctly), so either the onboard air driven pump or an external hydraulic mule has to be used.

Its amazing how those panels can take a 150+ mph wind.
well they take it at a fortunate angle :)
you do know that planes travel at about 650 mph right?
@@DingusYi He means when the doors are open and an enormous amount of aerodynamic pressure wants to blow them right off the hinges
@@DingusYiyou do know that they don’t takeoff and land at 650 mph, right?
@@swaviator9623 landing gear can still be down at about 275. Either way, OP said panels, and said panels are always exposed to the wind.

If you took the time to read, you would know it's water.
That guy on the phone with his back to the gear just makes me nervous.
He is probably talking to the guy in the flight deck

Is this the same time in flight?
Yes it’s just making sure the hydraulics are still good for service
No, they are swinging the gear to make sure they work after probably changing an actuator or something.
No, the engine driven pumps are on in flight and the gear swings faster.
@@justing42Engine driven pumps have nothing to do with the gear on the 767.

You'll only do it once.
never get in the way of moving parts
I applaud the engineers that designed the doors that close not only when the gear is up, but when the gear is down. Nice!
It's probably just a simple computer program that controls it, not sure tho.

Gear should always be fully enclosed when retracted. None of this 737 BS... And why? Because it looks cooler.😎

The world’s biggest jack stands 😆
Here for when the gear falls off because it’s missing crucial bolts. 🤣

The geometry on the brackets is making my head spin 😵💫
So if you don't read English that mean it's OK to step on the open doors ?
Is it supposed to make more noise than the engines ? 🤔
It would be great to see how the plane is held off the floor.
Big yellow jack stands. You can see two of them at the start of the video and again occasionally throughout holding the plane up off of the ground.
I performed and or assisted with many landing gear checks as Hydraulic Specialist in the USAF. We usually called it swinging the landing gear.
The 2 yellow jacks that you can see, and there is also a tail jack that isn’t visible in the video
t I must admit they looked way to small to be used here, my mistake. How many jack stands though? Must be more then 2 on each side. 8?

Because the engine driven pumps aren’t on. The electrical pumps can’t handle the volume needed to do it fast.
