Any B727's fitted with INS ?

TN 727's definately had 1 INU - used to link it to the autopilot through the AUXNAV selection. Waypoints had to be manually input, from memory they could have 10 at a time. 727 was a mighty machine - built like a brick sh!thouse and quick too.

Our L1011s and 747s all had 9 lat/lons at a time.

Hi aterpster,

I remember that when we performed a "direct to" - it would place present pos in waypoint 0 (zero), but then once it was sequencing from 1 to 2 etc, could we load another waypoint in pos 0?

What happened when it overflew pos 9? Did it go to pos 0 or pos 1?

USMS aircraft had dual Littons, the kind that to enter a Jet Route, instead of just J38 from point A to point X, you had to enter every single fix on the route individually

There is a long story on just why we had the Littons, to be brief, 99% of the pilots, including me, did not want them, but the Department Head/Chief Pilot did, so that is what we ended up with. He was long gone by the time you showed up, but you probably know who I'm talking about.

However, even those were better than the INSs we first had, they could only hold nine (9) waypoints. On trips to South America the guy in the right seat and sometimes the FE had their heads down updating waypoints for almost the entire trip plugging in new waypoints.

It was a true pain in the butt.

If you forgot to update when I flew DC10s you ended up in Lagos. That was enough to remind you!!

I never flew real international, only the L1011 LAX-HNL. 9 waypoints were a perfect fit for the R routes.

I heard a story about one of our sharper international captains deadheading westbound on the north atlantic on one of our few night westbound flights. He woke up and noticed the moon go by his passenger window. So, he went to the cockpit and woke up three guys asleep. The INS had sequenced to position zero, so they were headed for N 0 and W 0.

Or, so the story goes.
