Fair enough. However, my suggestion slightly differs: ;)
600' - AR; (1/4 nm) 1500' - IC; (1/2 nm) 3000' - IM; 4000 - X, BC; (3/4 nm) 4500' - BR
My guess is that the Start is where the pilot starts calling the ball, right? Given the approach speed of 145 kts, we'll have some 16 sec in the groove, and at 130 kts groove time will be exactly 18 sec... :)
And it's ok to add some randomization, or a window. But currently no dashed lines, sorry ;D

I would suggest something closer to 3600 for Start (X) because using a nominal LSO NATOPS Case I WoD, using a natural wind of 12 kts + 15 kts boat speed (27 kts WoD), I calculate about 3350' at 137 INDICATED (110 TRUE). If we get up to 145 kts INDICATED, we get 118 TRUE (145-27=118) for 3600' (3584' rounded up). This is all assuming an 18 sec groove time. The numbers obviously get less/closer with a 15 sec groove time; such as a Start (X) at 3000' (2987' rounded up) using 145 INDICATED (118 TRUE).

Let's get JJ's take on this and if the pass starts at pilot Ball Call or wings level on Final Bearing AFTER Ball Request.

No. Unfortunately they don't. :(
As you can see, the locus limits are not straight lines:
I'd say these lines are a function of the distance and the glideslope deviation...
FSX waveoff lights depend on the angle of view only. Thus you'll see flashing red lights even if you're in a safe position just below LO (or above H) somewhere at 2700-3000'...
------
As for the distances.... BC = 4000..3900', X = 3700..3600'. Are we agreed? ;)

Yeah, I see what you mean in the illustration, but shouldn't the vLSO waveoff calls be in concert with the boat waveoff lights and separate from the grading LOCUS.GS?
I'm asking this as a question not a statement because I don't know if the vLSO is already programmed that way or if its something you've already discussed here and I missed.
As for the numbers, definitely agreed!!

I think this is the piece we were missing, the RELATIVE vs INDICATED airspeed approach plus 4.0/3.5 glideslope differential in FSX vs real world numbers. Here's my thinking... the RELATIVE vs INDICATED airspeed gets us right into the ball park and IF we had a 3.5 ball, we could be on the correct RADAR ALTs (450 at THE 90, approx 1.2NM TCN), along with getting a slightly faster (+2 kts) approach speed due to a tad less uptrim to control on-speed. This goes hand-in-hand with how much we see real world Hornet videos doing in the 140s indicated while the default/Sludge are always in the mid-high 130s, even at MAX TRAP. BTW, this is how it was in the sim, the Hornet easily stayed in the low-mid 140s all thru the pattern and on final bearing approach.
I'll try to confirm all this tonight and see how close we get.
