You would think so, yeah. I'm sure some of it is. But in some cases there's enough tolerance stack and on some parts if they are getting bent or twisted at all (like wing skin sheets) the exact warp and stretch can vary slightly from part to part. May be enough that it isn't practical to do every hole until everything is actually aligned in the fixture. I know on thinner sheet metal wings, it can be very difficult to convert where the holes should be in 3D down to a flat 2D piece of sheet metal that is going to be bent to fit to an airfoil shape. On thin sheet the angle you drill at is a little less important but if you have thick skins and thick ribs, more of a challenge.

No , cz make prehole before assembly is more hard to work with, due to precise issue, cz sometime, we deal with mis aligment hole between 2 part, that why we assembly first then riveting, cz more easier..

Seems to me like it would take ages to cover the entire wing having to move the rig for every single hole

It's called HALOSENSOR system which is owned by ZB3 Technologies Ltd

It's cozier to do it from the inside of the wing

Have you ever been inside an aircraft wing? I doubt it. I have been inside the wing of numerous aircraft. They ALL have wire, fuel pumps, fuel xfer lines, fuel vent lines, fuel capacitive probes, densitometers etc......

Um...come on now jose..this is construction..why would u add all the hardware during construction.....

@@-covid-20 > Jose is just an ignorant fool. He doesn't know a damn thing about aircraft. He doesn't even seem to realize that there are millions of workers working on aircraft, manufacturing, maintenance, fueling every single day. Most of these are hourly workers and in many cases union worker. Some how all of these workers are in on his big conspiracy. We are all some how hiding his big conspiracy. HE IS A COMPLETE IDIOT. The sad part is that he doesn't even realize how dumb he is.

@@rcairflr The really sad part is that he might have offspring some day.

Call up a flight school dude they'll show you where the fuel is stored

You're looking at them. The aluminum is sealed off with black liquid rubber, and bang, you have a fuel tank!

in some walt disney production.

The manufacturers do extensive loads testing on the wings to make sure they don't break. For anyone not involved in aircraft developement, you would be surprised at the amount of testing that is done on aircraft before they ever go into production. Manufacturers spend billions to test aircraft .

If you didn't mind Denny Laine, they were great in their day.

That's ok! If you haven't drilled wings at Boeing or Airbus you don't have any reason to understand what they are saying! :)

I'm lost too. Why not just drill from the target side?

Most likely 7075 aluminum alloy.

It may look time consuming and expensive. But I'm sure it saves more time rather than replacing misdrilled parts and the cost of replacing them as well. As a sheet metal specialist time is nothing you want to keep track of. Just do the job deliberately and slowly. Drilled right the first time every time.

It's almost like they're building an airliner or something

Actual mechanics can drill straight holes without this bullshit lmao

@@al69420 yes but can a mechanic drill 50 of them every hour?

they use suction cups

Why not ask a flat-earther?

Kevin Taylor probablly you did not understand that halo tool is recommended only for alu aloy.

@@dimitriskaligeris5506 we use it on carbon also.....

Mac Delaney due to expansions and other various factors i think

Pre-drilling doesn't take into account the position of the matching holes in the other structure's. e.g... setting the pre-drilled metal over the other existing holes on the mating piece may not line up because of various precision variants.

yes on a little kit do it your self plane.

Match drilling is the only way known to man that can produce accurate alignment. Usually they use fixtures to precisely locate a few reference holes and then match drill/fasten the rest.

should work fine with ferous metals

i use a similar thing for drilling holes through walls,,,,

And what is that?

I’m an aircraft mechanic and it’s awesome...for the first 5 years. Lol
