How is the INS aligned at sea on a carrier that is moving at 30kts? BRBR

Ouch. Here I thought I was a stud. |:-)

Two axis VGI, TACAN and ADF, cockpit lighting by afterthought, single
engine, "interesting" dirty flying qualities. A night in the life I'm glad
is far behind me.

OBTW, T-45 GINA (integrated GPS/INS) has no SINS cable. Uses GPS in the
ship alignment mode and must calculate ship's movement null factor (whatever
the hell that is). From power-up: Full alignment on concrete = 3 minutes.
Full alignment in flight = 6-7 minutes. Full alignment on flight deck =
16-24 minutes. Go figure.

John,

Hornet EGI (Embedded GPS/INS) produces fairly similar numbers--slightly
longer for the concrete alignment (5-6 mins for the full 0.5 OK). Using the
GPS to generate POS/AINS (aided nav) is at the pilot's option.

GPS IFA's in flight take about 6-8 minutes. CV on-deck alignments are about
12-15 or so depending. Although on my last cruise I found myself
occasionally wrestling the jet through 3 alignments before getting the third
one to take (about a 25 minute evolution) with the Boss querying me for a
status as I took the third one.

C'mon John, didn't ya enjoy being 'lost' everytime ya lost sight of the CV?(Me
neither)...

I remeber one transit(VF-151, Midway-Maru) where we flew, daytime, complete
Ziplip, just to FAGAT, but the F-4 guys had to stay overhead the CV, so not to
get lost. Interestingly, the only guy to break ziplip was a A-7 guy who's
system crashed...

Try doing a "must make it" approach into one of our winter wonderland
seismic strips on Melville Island NWT (That's just past Resolute Bay for
those that don't know the North) with 100 + nuthing in snow using an ****ty
DG and a very good set of Eyeballs, or motoring around the Beaufort Sea with
ADFs and a very erractic Omega. Of course this wasn't combat as no one
except the locals were shooting at us when we were in Alaska flying out of
Barrow. (wait a minute isn't that the same thing?) I found a few 30-30 holes
in our Aztec so I guess that applies
Sum of us old Farts really like using the new stuff after those days

Gary,

Of course this wasn't combat as no one except the locals were shooting at
us when we were in Alaska flying out of Barrow.

Sea story time.

When RA-5C community set up shop at NAS Albany, GA (ex-Turner AFB) they
brought with them a quaint Naval Air tradition unknown to those whose
aviation horizons had been limited to the Blue Suit way of life:

Night FCLPs.

One of my RAN buddies told me that he saw more muzzle flashes over the
approach end of the duty runway than during two cruises over Route Pack 6.

So you don't need to freeze your cajones off to have your aircraft shot at
in North America.

Night FCLPs.

Here locally, MCAS Beaufort has it put in the local newspaper when
FCLP's are scheduled. They are all back on the deck by put to bed
by 2300.
