While I commend their interest in technical and operational issues, some things should never be revealed or discussed in these forums. And, this isn’t one of them. As stated before and linked, there is plenty of open-source material available on the internet that shows all of the stuff being discus...Jump to post

Am I sure about that? with about 12,000 hours on various models through the 100, 200, SP, 300 and 400 freighters and PAX versions, YES!

The 747 one is shown quite well on a Sam Chui video where they climb up an old stored one in the desert, they climb up on the nose gear and them up into the EE bay and then through a panel in the floor of the old first class. Back when I was a newly minted, youthful and energetic A&P, I would c...Jump to post
Yeah, the Whale has one. A friend, who was a wrench on it at UPS loved to tell of diverting into King Salmon and using it as a way to the ground to order fuel. No stairs available. Yes, but that is the normal E&E access in the floor of the main deck. Six’ish feet below that is the exterior E&am...Jump to post

On the 747, there is a bulkhead door in the fwd wheel well. No warning light in the cockpit. Sure about that? MD11 has one that I only found out about recently. Never saw one on a B747.

iPad went a little screwy. If a jet engine is at idle thrust, does the thrust level have to be adjusted for ground, air, altitude?

Sounds a bit dodgy to me. With all due respect to Russian technology, they would be the last manufacturer I would think would have advanced technology to the point of being able to avoid physics.

They are indeed panel “seams”. Fun fact: we referred to the ones over the engines as “gap covers”, and they had about 100 screws of 4 or 5 different lengths and the had phenolic fillers in some areas. Fun. We had those things up all the time. Wire bundles make some 90 degree bends under the cover an...Jump to post

My guess is that it’s used to shore a wing when certain maintenance tasks are performed. Looks just like what we’ve built to just that.

Seen it plenty of times on plenty of different aircraft types. It's not fuel or hydraulic fluid, so, past those considerations, never gave it a another thought.

I think the biggest "Problem" with Clancy adaptations is that they do have so, so much story in them.

By the way, temperature is usually used as a parameter to moderate HPC air. HPC air can easily over-temp the pneumatic system. The HP Controller and/or PRSOV, or equivalent, will choke down the air to keep the temperature within acceptable limits. I guess I should elaborate, in the interest of clar...Jump to post
Normally the bleed air is extracted from the low pressure compressor No. Bleed air is almost always taken from the high pressure compressor, but from an early stage…5th on the CFM, as I recall. This is low pressure air. It is supplemented, at idle or under heavy demands, by high stage air…maybe 9th...Jump to post
I'm not sure where you're headed here. There are plenty of checks and balances in aviation. Trust but verify is very much alive in aviation. Certain mechanic's work is checked by an inspector.

I don’t think it would interest an A&P, just too much work. Really? I know quite a few A&P's that have taken on restoration projects. It's a hobby. Not for me, but to each his own.

Walk away. The guy said the engines are "locked up". I heard "frozen by corrosion". Truth is, I wouldn't worry too much about the airframe and interior, that's straight forward restoration work. That would be a good project. But, the engines? Those are probably good for boat anch...Jump to post

I remember when we were doing RVSM certifications on our DC8, the air data settings appeared way out whack. Varying airspeeds at different altitudes, some seemed very extreme.

Does the this attrition lining extending past the fan, also have the same acoustic dampening properties as the inlet liner forward of the teal liner?
I was really surprised that posters were suggesting that the teal liner was an attrition/abradable lining. As you point out, the teal material extends many inches ahead of the fan. So it's not that, folks! Yes, it is. I suspect the reason the liner extends forward of the fan is based on the structu...Jump to post
I kinda like the idea of a head of state…a ceremonial leader who, while not ‘of the People’ nor representing the will of the People, represents the People.
The head of government does the dirty work, the head of state sits above it all and does the hand-waving.
