Magnetic or True North?

[A4sForever]

There's a book out there, I think it's called the LHA/LHD NATOPS MANUAL (NAVAIR 00-80T-106), that defines the BRC as: "base recovery course (BRC). The ship’s magnetic heading during flight operations." (I cut and paste the definition so nothing could be lost in translation.)...

LHA/LHD (whatever THOSE are) and CV/CVA/CVS NATOPS: F.Y.I for all of you-all ... since there seems to be some 'discussion' on the topic --- BRC IS ALWAYS/HAS ALWAYS BEEN MAGNETIC !!!

W/ apologies to Martha Stewart: it's a good thing.

I only have one question: any questions ???

Exactly. This all sounds very familiar...almost like someone posted this stuff a few posts earlier.

I dunno ... until K-Bay saved the day, this is all I remember reading: " I can't remember for the LHA Natops"

..the only thing we're concerned with around the boat is magnetic (BRC) and relative (winds over the deck)...

We had this and similar 'arguments' 40 years ago ... and in a perfect world: while these aren't necessarily the same, what about 'final bearing'??

FINAL BEARING. Which is what counts for fixed wing drivers ...

If they're not the same (relative wind & final bearing): shouldn't they be ... ???

Good BOAT drivers can make it happen ... why can't all of 'em ???

Touche. But BRC is BRC, regardless of the boat or pub...ie, it's magnetic.

The potential problem there is when you introduce anything w/ a "F" in the name, the small-boy Shoes will give it to you in true, again because of the ATP-1. You're right, though, FB is what matters, and not just to fixed-wing guys. Like I mentioned earlier, it's an issue for helos going into a non-LAMPS ships or the "smaller" gators.

I've always heard that if it's written it's True if it's spoken it's MAG

Your Air Boss is wrong and probably just lazy. The gauge in the tower shows the ship's course in true since that's what SWOs speak. It probably wouldn't be too hard to make the gauge correct for magvar, but they don't - the boss has to do math before passing it.

With that said, the BRC is a perishable value anyhow. More than once I've broken out on a Case III approach staring at the side of the island because the boat turned mid-approach.

Always remember, the boat is trying to kill you. The Gator Navy just seems more dedicated to the cause.

Good BOAT drivers can (most of the time)...exception: When recovery is required with calm natural wind, the ship may have to make it's own wind. Artificial wind is by definition "axial wind" irregardless of FB, therefore is an approx. 13 degree stbd crosswind regardless of ship's heading. Even the "best" SWO can't overcome that.:icon_help

60B will give you both...as long as you have the correct MAGVAR entered in Nav Parameters ...Oops!

But when in True, you don't have any kind of course guidance nor DME, which makes it kind of worthless.

Indeed...however a moot point for me now, going back to the TH-57, and probably never touching a 60B again...

You need to get out more

Non L-Class ships are far worse than any Amphib I've ever worked with. That said, Shoes are still Shoes and even the best Gator bridge crew seems to have an uncanny knack for putting the ship in the middle of the only rain in a 50mi radius.

You heard wrong. Per LHA nd CV Natops, BRC and FB are always magnetic.

Never say never. I once thought the same as you. While not part of the "normal" food chain, I still seem to find myself in a -60B again, albeit Block 0's.

Tell me about it! This week, I had to put on my Safety Officer hat and personally visit a DDG skipper pierside. He was getting underway Monday for a few days of aviation services (our squadron going first Tuesday night) and he wanted one of our pilots to get underway and spend the night and then be on the bridge with him for our DLQs. My OPSO chuckled into the side of the phone and offered to send me over for an hour for a warm fuzzy brief. I got there and spent about 30 minutes explaining how we were not Bravos so we were not going to ask for RAST landings. Another 10 minutes to explain that we were not going to HIFR. Then another 20 minutes on the flight deck where he pointed at and asked me what each line and circle meant. Seriously, I cannot make this stuff up.
