New version [WIP]

Dear fellow simmers,
I've been working on a new vLSO version for a year or so. Yes, this will be a new version, not just another beta. The most noticeable feature of this version is its new design with custom skins:
Less visible but no less important options are all FSX and Prepar3D versions support with separate configurations for each sim, integration with RFN gauge, an optional practice carrier with adjustable WOD, user activated calls (ex.manual calls) now with joystick support, more convenient debrief window etc.

Another option I'm going to add to the program is using real WOD calls when applicable. For sure you did hear such calls like 'Roger ball, 23 knots' on numerous carrier videos.

I already have a number of good samples for WOD calls from 23 to 29 knots and a single call for 38 knots. But a whole range of calls from 30 to 37 knots are still missing.

So, I have a favor to ask you guys, if by any chance you have such missing samples or know places where to get them (mostly youtube videos?), could you share them?

Correction. I just got 2 sample calls for 30 and 31 knots, so the missing calls are 32 to 37.

[EDIT] FSX carriers' inconsistencies

Ok, guys

When working on the RFN gauge integration into the next vLSO version I've noticed certain inconsistencies in OLS-wires placement on different carriers, namely on the Acceleration and Javier's CVN68.OLS hereinafter means the Acceleration embedded FLOLS.
Well, I googled a blueprint of the Nimitz and then compared it against the two models:

First thing that you will notice is that the Acceleration model is smaller and loosely reminds the real ship, while Javier's carrier almost perfectly matches the blueprint, which seems to prove that his model is the most accurate. However, the most significant difference (not visible at first glance) is that Javier's OLS and crossdeck pendants are shifted to the stern. Also, you can notice different spacing between wires - the green crossdeck lines above show Acceleration wires and the OLS datum line, the yellow lines show Javier's ones.
This zoomed view displays these differences in more details:

Then I placed an airplane on the deck of these carriers in a position 'on glideslope' to see where it should touch the deck.
'On gideslope' ball as seen from the cockpit

The Acceleration - right on wire #4
Javier's - well past wire #4
Huge disappointment!

Is there a carrier with correct wires-OLS positions, one might ask? Yes, there is. The Team SDB CVN65 in configuration with the default FLOLS. The 'on-glideslope' position on this carrier matches wire #3:

Another comparison screenshot proves that. The green line corresponds to wire #3 of the Big-E.

So, what's the point? What all this means for us? Well, it means that even flying on the ball you shouldn't hope to catch wire #3 on existing Nimitz models. Otherwise you should intentionally fly low at the ramp...

As a workaround you can use the RFN gauge, but in this case you shouldn't take the OLS into account and fly RFN needles exclusively.

======  EDIT  ======

The Aerosoft CV63 Kitty Hawk utilizes a RFN gauge (with its inherent precision). You can see that when flying on the ball you should land right in front of wire #3:

Actually, this gauge is kinda MOVLAS, not FLOLS, and the ball corresponds to your position on the glideslope. The RFN gauge controls the ball the same way as a real LSO controls a MOVLAS.

The survey results

First of all I'd like to thank every one of you who took part in my survey. 
Well, here are the results of your 99 responses:

As you can see, FSX keeps its first position as the most frequently used simulator, followed by FSX:Steam Edition and Prepar3D v3 neck and neck. Quite surprisingly, Prepar3D v1 is still being used. Honestly, I was about to remove its support in the new vLSO version, but definitely I'll have to keep it there.
As I expected, most of you have two (or perhaps more) flightsims and fly them on a regular basis, so the new vLSO version will support any number of simulators, currently up to five, installed on the same machine.

During my last downloads reordering I erroneously published an outdated download link as  the latest My bad... Please check your vLSO version and download the right version if required. Sorry for this inconvenience.

This version is my another attempt to minimize the annoying effect of the 'Light on deck' calls.

The program now checks the lights and gives the warning every 20 seconds 1) no more than 3 times and 2) only after you landed on deck. This means if your mission starts on the deck, you won't hear these calls.

The setup option introduced in the beta is still valid. Maybe I'll remove it in the future...

A small update once again - you can now disable the exterior lights check (if you find it annoying). This option is a subset of the NATOPS option, that is, if the NATOPS is disabled then the 'Lights on deck' is disabled as well.
Just download and replace the vLSO.exe file.

To not clutter the blog, I have removed the two previous .exe downloads ( and

This is another small update to the program - the CASE info being added to the export formats CSV and XML (at Scott Gray's request).
Just download and replace the vLSO.exe file.

Here's another small update.
- Even more strict Ok requirements introduced
- A weather reporting error corrected (my guess is that this glitch caused frequent 'N/A' floating point errors)

Happy landings!

Well, another small update. Just two changes - now it's harder to score an Ok grade and the Virtavia A4 Skyhawk is supported by default.

Happy landings!
