Coast Out/coast in
 

Couldn't find a definition on a search although I have an idea. Anyone care to comment and if they still do this on their transoceanic flights.

Are you talking about a NAV accuracy check?

Our company is dragging the old procedures into the future. For what? I do not know.

Yes, Nav accuracy check. Any details.

Verify ANP vs. RNP.

Yes. We do this every time we don't have GPS PRIMARY. Which adds up to 0 times in my career.

We now check IRS drift, but no longer have to do a VOR/DME crosscheck.

Our operator still specifies the need for a "Nav Accurcay Check" requirement prior to going remote....but doesn't say what it is!

So is the definition of coast out the last update or check done on your nav system?

Probably another tick in the box to cover for lawsuits.

Hey, there is a publication - I have done my home work, when I thought I was going to fly the A330. Listen up, CPDLC included . . !

Wow, I am surprised anyone ever left or had time to do all that on a NAT crossing... :}

Dunno how we have done it so far...

There's a lot of things people don't do these days. One guy told me, "I have a magenta line. Why do I have to do plots to verify course enroute?"

I wonder how many of the new-age "magenta line boys and girls" could accurately plot a deviation on a chart?

They probably can't take an astro noon shot either!!!

Well plotting was ingrained to me as a junior F/O flying DC-8s with Litton INS (pretty good) and OMEGA (really bad) across the Atlantic. Still done in my cockpit, even if we have fleetwide GPS/RNP/ANP/YOU NAME IT...

Har har, very funny. It was only an aide memoire.
