Pitching Deck
By Orion Lyau



Your radio comes to life with the landing signal officer's voice. "Three quarter mile, call the ball," he says.

Visibility is bad, but you're just able to discern the light from the ball. "Three zero one, Hornet ball, four point two," you call back. This is going to be one heck of a landing. Rough seas and low visibility make one of the most challenging things in naval aviation even harder.

The LSO acknowledges you. "Roger ball, 33 knots down the angle." The crosswind is buffeting your aircraft, throwing you off course. Your ghost vector on the HUD is way off to the side. The LSO's voice comes back. "A little power. Come right." You react accordingly.

The carrier is now clearly visible in the midst of the clouds, deck pitching and rolling. You follow the ball for a stabilized approach. As you pass over the fantail, the deck heaves up. You snag the two wire, and quickly come to a complete stop. You're down.

And now you too can experience the challenge of landing on a pitching deck, from the comfort of your desktop computer. In this new version, an improved and more intuitive user interface allows you to easily create pitching and rolling boats for Microsoft Flight Simulator X. If you're lost, you can request your bearing and distance to the boat to help you find your way. You can now also control the period and amplitude of the pitch and bank independently from within the program itself. And by popular request, there's even a new option to freeze the boat attitude after landing.



Prerequisites:


Installation:

  1. Download the file below.
  2. Extract the files contained in the ZIP archive into a new folder.

Uninstallation:

  1. Remove the folder you created in installation step 2.



Features:

  • Intuitive interface
  • Pitching and rolling deck
  • Boat directions (bearing and distance)
  • Variable period and amplitudes
  • Option to freeze boat attitude after landing
  • Custom location files
  • Persistent settings
  • Built in updater
  • Compatible with vLSO

Usage:

Z4MIt7i.png


Click Connect when you have Flight Simulator X open, and click Create Boat when you want the boat to be created. To change the location or boat, select a preset from the drop down menu, or enter data in the textboxes manually.

Title refers to the SimObject title, as seen in the sim.cfg file. Latitude and longitude should be expressed in decimal degrees. Heading is in degrees, and speed is in knots.

The sliders for the pitch and bank amplitude are in degrees. You can adjust the period (time it takes to go from the maximum amplitude to the minimum, and back to the maximum) of the pitch or bank by changing the appropriate frequency slider. The maximum frequency (100%) creates a period of approximately 6 seconds; 60% is approximately 10 seconds, and 20% is approximately 32 seconds.

To request directions (bearing and distance) to the boat, press Tab+Q while in the simulator.

Data entered in the textboxes will not be saved. If you wish to create a new preset, you can create an XML file similar to the one below:

HTML:
    CVN68_1
    21.2333333333333
    -157.833333333333
    142
    25
  
  
    CVN68_1
    28.374
    -80.476
    160
    25

Then locate the PitchingDeck.xml (in the same directory as PitchingDeck.exe, created after first run) and add a new LocationFile element with the path to your new preset XML.

The example above contains two locations, but you can have as many or as little location elements as you wish.



Known issues:

  • Carrier lights (e.g. IFLOLS and runway lights) do not pitch with the deck.
  • Catapults become disarmed as the deck pitches. You can work around this by either enabling the freeze carrier attitude after landing option, or by launching immediately after arming the catapult.
  • Some aircraft may exhibit a slight bouncing behavior while on the pitching deck.
  • The carrier may jitter if the frame rate is not consistent. If you find the carrier to be jittering, consider locking your frame rate to an attainable setting.

Sheesh! As if I don't have a hard enough time when it is dead calm.
Yes please post a vid or at least some pics.

It's a bear! Ran the S-3B Viking a few times. It throws a whole knew monkey wrench into things!
 
Sheesh, you guys are a tough bunch to please! I spend months writing a program and now you want a video on top of it!? :dizzy:

I jest, though, making a video, as it turns out, is quite a bit of work. And without further ado...


Also, glad you like it StormILM and Bill. :)
 
AVG free 2014 considers that the exe file is a thread, and blocks it. Has anybody else had problems with this?
 
Crap, this is scary! I should have bingo'd to the beach, as the seas were too rough for flight ops. For me anyway... :) This is pretty cool. Nice work Orion! I think I will calm the seas just a bit for the next go...

Ha Ha. Well....at least you're down. Great program. This I just have to try (even if only once?).

Orion, I'm having a lot of fun with this. You've got the pitching and rolling motion down beautifully too. It isn't "unrealistic", IMO. The other fun thing about this is that now I can drop a carrier (Akagi?) oh, about 200 NM north west of Midway Island, course 075, speed 20, then take off from Midway in an SBD and try to find it, without using CTRL-Z! How fun is that? :) I did tweak the waves down a bit from "Halsey's Typhoon" to "Normal rough day in the Pacific"...

I've talked to pilots who have made approaches to carriers in high sea states, and they always describe the feeling as "being too high", then "too low" due to the appearance of the deck from the cockpit. This demonstrates that affect perfectly! Very cool.
 
It was getting late. Just returned from a four hour search mission from Lex. We were in the Coral Sea. We had word the Japanese were on the move, about to invade Port Moresby. We were sent out to look for the approaching invasion force. Scuttlebut sad the Japanese navy was on the move too, and we might meet them here, in the Coral Sea, in the coming days. I was just tired, and looking forward to a sandwich and some coffee in the CPO mess. But first I had to get aboard, and the weather was, well, stinko...

 
Nice landing Paul.:applause: Have you tried adding the rest of the task force with aicarriers (Yorktown and escorts)
with this app running as well? Lady Lex looks really lonely out there in enemy territory.

Why you make video so dark? I can't really tell what's going on here. Pitch, but no roll. Sorry, no credit card here. LOL
 
Glad you like it Paul and Napamule. :)

Paul: could you edit my initial post in this thread and move the video I posted yesterday to where the program screenshot currently is, and move the screenshot between Usage and the instructions? Thanks! Also, just curious: what are your "Normal rough day in the Pacific" settings?

It's dark because it's a dark and stormy night. Can you see the roll in this video? If you still don't think it's enough, try landing on this:


Make your own video if you don't like it. Or just try the program for yourself -- you do realize I'm giving it away free of charge?

Orion,
We see that the program works as advertised, it makes carrier ops more challenging and as freeware it is much appreciated. :encouragement: Don't let one comment about the video get you fired up.
 
Thanks TARPSBird. I actually had that video from when I was testing and inadvertently set the amplitudes too high, but I found it too relevant not to post. I just find it irksome that dvj has had nothing constructive to say when I've put so much work into the program and video, and provided it for free. As a disclaimer, I do have an option for those who would like to donate (a small label beneath the advanced options within the program), but as I labeled it, it's for those who feel charitable and appreciate my work; those who don't are free to ignore it.
