I loved the smell of "dirty purples." Can we get them to put those in our vfiles? (note the use of the word "vfiles," and they said you can't teach old dogs new tricks)

LTN-92 Ring Laser Gyro Inertial Navigation System

The LTN-92 Inertial Navigation System (INS) is the world's leading laser gyro replacement for the mechanical INSs used on many military transport and commercial aircraft, including "classic" B747s, DC-10s and L-1011s. The LTN-92 uses three ring laser gyros, force rebalanced accelerometers, and three high-speed digital microprocessors to provide an advanced technology, all-attitude, worldwide navigation system offering up to five times the reliability of mechanical inertial navigation systems. The system’s ability to manage internal navigation bulk data storage allows for comprehensive worldwide flight planning.

You are right, we were running the LTN-92 in TMIX with DME/DME update on the B747 classic and the DC10s. I know some operators were using the system in Dual mode with just two boxes.

Before those upgrades we used the older Delco Carousel, we also used three of these, but our units only held 9 waypoints, I know some other models would hold up to 150 waypoints. Not sure what units you used, so I thought the OP had the LTN & Delco mixed up. No big deal.......

It's all Amish went compared to a B777 or A380.

Thanks for the background info Cohiba.

A little too much caffeine this morning, Johnso?

I once had a captain tell me that he doesn't run both because he doesn't want to "over-pressurize the duct work." That was amusing! Some of the gate A/C's work really well and some don't. That's one of the first things I check when I step on an airplane.

Just brewing my 1st cup now.

forgot to bid

well, I guess, one way to do it is just do it without asking and then see what they say. If they're not happy, say, "sorry, everyone - including the LCA I flew with last week - told me to turn it on if its hot. I guess thats coming from the LCA meetings, they're making it a priority. Read it online."



FTB, always just flew with a LCA.

We need to start an education campaign for the underwing guys and lav trucks on hose kinks and the 88, which of course has the shortest distance from jetway to where the air hose goes. I was in CMH, they claimed they had a bad hose, it had 7 kinks in it. I took most all of them completely out and the hose had a straight 10' going into the plane, it worked great. Thats not saying anything about CMH, ATL is horrible about it. JAX actually has a dolly that their hose sits on to keep it off the ground and in a way it minimizes kinks.

As to freebirds point, I think we should all have to DH on an 88 once a month or so in the summer. Just to know what goes on in the back. However, every one of the CA's I've flown with all summer have been anti-heat and turn the APU on- but we've got what, 1000 pilots on this plane in ATL alone? It only takes 1.

I would just start the APU. If a captain doesn't like it and wants to shut it down so be it, but if I am too hot to safely work...... Well I am just saying

forgot to bid

Good point.

Also, open that window. Its 95F and humid and loud.

I wouldn't worry about overpressurizing the ductwork, but I don't see the point of using two different cooling units, at least one of which runs on a thermostat, to try to reach one temperature. Either the ground air works, and it's cold enough; or it doesn't, and it'll fight the APU.

If you need the APU, get the air disconnected. How complicated could that possibly be?

Also, some of the fleets can't cool down efficiently when running recirc fans: the air that's picked up often comes from the cargo compartment, which is open to the hot (and often humid) air. Another great example of fighting yourself.
