The Pitching Deck Saga
micro:
Sorry for the delay fellas. Well, here is what I have so far on the pitching deck: long story short, the deck was made to pitch by slewing the pilot-able version of Javier’s carrier. I chose that as my “aircraft”, raised the altitude to about 30 feet, and then started pitching with my stick. I recorded it with FS-Recorder, and then played it back to land on.
Now, because it is technically an aircraft dressed up to look like a carrier, the meatball does not work. So what I’m trying to do is take track of the pitching carrier and insert it into a mission where the real carrier plays it back. That way everything will work, and you might even have a tanker on station to really get your blue water jollies.
If you open up the sim.cfg for the carrier, you’ll see a line at the bottom that says “static_pitch”. While tinkering with that I discovered that the FLOLS is actually stabilized (kind of). In the following pictures I set the pitch from +1.0 to -1.0 hoping that would get the deck to start pitching.
Unfortunately the deck stays at the pitch angle you set, but if you notice, the ball is not “physically” attached to the model. It kind of floats in its normal position giving the illusion of being stabilized. The problem, as you can see, is that as the bow of the ship goes down, the deck actually starts to obstruct the ball. Just like in real life, the solution to this would be to have a higher than normal glideslope (3.5 – 4.0 degrees). Maybe someone out there with a knowledge of the FLOLS in Flight Sim can tell us if that is possible, but I would have no idea how to pull that off.
As for making the carrier itself get a pitching motion: according to the guys at FSDeveloper it should be possible, but for the moment it has a lot of people scratching their heads (go to fsdeveloper.com forums and search ‘bobbing’). That’s why I’m trying the mission route. That is where I am at. I would gladly appreciate anyone and everyone to join in on this project. Maybe together we can knock this out.

Hi, micro, thanks for the update! I can say from my experience with the carrier-ILS-capable HUD, that the ball is set at exactly 4.00 degrees, for both the default and the Nimitz carrier. I don't know if that helps. It's pretty high, but because in the carrier missions the carrier is moving at 35 kts and there is 10 kts headwind, that 4.00 degrees is a good value. The route you're following seems correct, I'll scratch my head too, see if anything comes up ;D

I can look around and provide some insight, but I'm no expert with carriers. I'd love to see pitching deck ASAP, so I'll look around.

USN LSO NATOPS might interest those looking at the pitching deck and associated issues. Graphic from one example (there are many online with different publish dates but the data is mostly the same): http://www.navyair.com/LSO_NATOPS_Manual.pdf (1Mb) EDIT Matter of fact same PDF (one of the smaller example PDFs) zipped should fit here BELOW.

You're really a PDF ninja. ;)
