Greenie Board Possibilities?
Paddles:
Very useful post, thanks Spaz!
I think it's time to get into more details. Most of the areas I planned to arrange are in place already and here you can see the layout (don't be confused of that red wireframes mess).
I used approach figures from the latest LSO NATOPS available (of may 2009) and calculated (millimeter-wise) GS areas geometry for Javier's CV68, which is known to have the glideslope angle 3.99 and the deck angle 8.496. The GS distances, shown on the picture, are measured from the ramp.
There are 7 areas for lineup deviations (_LUL_, LUL (LUL), OK, (LUR), LUR, _LUR_) and 7 areas for glideslope deviations (_H_, H, (H), OK, (L), L and _L_) at each part of the approach. So, it will be possible to reliably define aircraft's position/deviation. I also plan to monitor AoA, sink rate and other aircraft parameters such as flaps, gear and hook positions...
And here is my question. ;)
What do mean \ - fly down through the glideslope and / - fly up through the glideslope? Or when these errors are recorded? I mean that during its approach the aircraft constantly flies up and down through the glideslope, as the pilot constantly makes corrections. So what are the criteria?
Thanks. And more questions to come... ;D
SpazSinbad:
fsxnp, WOW - looks like you have an excellent idea of how to go about the task.
Not sure about your question:
"What do mean \ - fly down through the glideslope and / - fly up through the glideslope?"
I'll do some thinking and investigation. I gather this criteria is in the latest LSO NATOPS May 2009. Every other day I search the internet for the latest 2010 LSO Reference Manual PDF - no luck. ;D

Fuzzy Logic PDF may be inspirational - or just plain FUZZY:

SpazSinbad:
Found the 'fly up' & 'fly down' through glideslope references here online:

FROM this CNATRA T-45C pub: http://www.tpub.com/content/aviation2/P-1211/index.htm
Is this the standard? I hope it is seen that comments differ over time whilst there is some flexibility as well.
Paddles:
Spaz,
Good reading about fuzzy logic, it IS inspirational, not fuzzy ;D thanks!
Down to my question. Just an example. Say, I start a little low and make correction. Sure I will cross (fly through) the GS and will be a little high. Then I'll try to compensate and go down again... These small oscillations are inevitable during the approach. So, when or why these oscillations are considered as / and \ ?
