[Flightgear-devel] VASI
Does anyone have any specific dimensions for the layout and size of a VASI system? >From what I've been able to find, the VASI/PAPI system should be 50' off the side of the runway and about 950ft/285m from the threshold. I know that each of the 4 PAPI lights is spaced about 9m/30ft apart. But, VASI seems to be the 'old' system and I'm not having any luck finding any documentation on exactly where the VASI is placed and exactly how the lights are laid out. I believe that VASI is placed the same as PAPI, but I need to figure out exactly what the VASI looks like.

[Flightgear-devel] VASI
According to the U.S. Navy: http://www.efdlant.navfac.navy.mil/Lantops_15/topics/Facilities/NAVAIR_51-50 AAA-2.PDF see Section 003-11 for VASI, Section 003-12 for PAPI The first (downwind) VASI bar should be 600 feet from the runway threshhold, and subsequent bars should be 700 feet upwind. Most civil installations use a three-bar system, with three lights in the first and second bars, and two lights in the last one. VASI bars are located on both sides of the runway, so a three-bar system has 6 bars and 16 lights. In each bar the light nearest the runway is 50 feet from the runway edge. The other lights(s) are spaced 16 feet apart. I deduce from the drawing that the first bar lights point at an angle of 2.5 degrees above the horizon, and the other two point at 3 degrees.

[Flightgear-devel] VASI question
I was shooting an approach with FG and noticed that when I pitch up the aircraft, the VASI lights turn white. Similarly, when I pitch down the aircraft, the VASI lights turn red. I loaded the UFO and verified the VASI lights change color when the UFO is stationary and the pitch of the UFO varies. Is this a known issue?

Here's an excerpt from the Canadian AIP: Approach slope indicator systems provide safe wheel clearance over the runway threshold. The vertical distance from a pilot's eyes to the lowest portion of the aircraft in the landing attitude is called the EWH, and this distance varies from less than four feet to up to 45 ft for some wide-bodied aircraft, such as the B-747. [snip] Visual Approach Slope Indicator System (VASIS) V1: 2-BAR VASIS intended to serve aircraft with EWH up to three metres (ten feet). V2: 2-BAR VASIS intended to serve aircraft with an EWH up to 14 m (45 ft). V3: 3-BAR VASIS intended to serve wide-bodied aircraft with an EWH up to 14 m (45 ft). AV: AVASIS intended to serve aircraft with EWH up to three metres (ten feet). PAPI (Precision Approach Path Indicator) P1: PAPI for aircraft with EWH up to three metres (ten feet). P2: PAPI for aircraft with an EWH up to 7.5 m (25 ft). P3: PAPI for aircraft with an EWH up to 14 m (45 ft). AP: APAPI for aircraft with an EWH up to three metres (ten feet). I imagine that the main consideration is runway length -- if the runway is 8,000ft, it doesn't hurt a C172 to come in 40 feet too high over the threshold, and if the runway is 2,000ft, transport jets won't be landing on it. There are aerodrome standards online, and those probably include VASIS and PAPI placement. I could point you to the Canadian ones, but I'm sure the FAA has the U.S. ones online as well.

re: [Flightgear-devel] VASI
Yes, there are definitely complications, but right now our data has N=none, V=vasi, P=papi, so I'm planning to start simple. What I'm looking for is somethingn to the effect that a VASI light bar is a row of "n" lights spaced "x" meters apart. VASI light bars are spaced "y" meters apart along the length of the runway. And if I'm really lucky I'd get the difference in degrees in alignment between the two/three light bars. I.e. bottom bar turns red at 3 degrees, top bar turns red at 3.25 degrees (or something like that.) Regards, Curt. David Megginson writes: > Curtis L.

Re: [Flightgear-devel] VASI
For the U.S., the numbers are documented in the AIM to give the angles etc for both 2-bar and 3-bar VASI and normal PAPI systems. Generalizing: A 2 bar VASI is simply a 3 bar VASI with one of the bars missing so I recommend doing 3 bar units consistently everywhere. The PAPI unit has all the lights at the same location, only the angle for the color change is different. Therefore, aircraft that need a greater threshold crossing height for the pilot viewpoint are forced to use a steeper approach angle which is inconvenient for them. In contrast, the VASI has small aircraft use the two nearer bars while larger aircraft use the two further bars. This provides both a steeper angle for large aircraft as well as additional distance down the runway which in combination provide the needed threshold crossing height. As a result, the descent angle for wide bodies is less steep. > Yes, there are definitely complications, but right now our data has > N=none, V=vasi, P=papi, so I'm planning to start simple. ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

Well, I'm all googled out and I still haven't come up with anything for VASI (although I have good data for PAPI.)

I am not sure that there is a 'regulation' that states this exactly my reading of the above link indicates that things vary on an airport by airport basis in that local conditions vary and it is the overall 'effect' of the lights and the 'pathway' they mark that is regulated My reading of this australian document seems to confirm this http://www.casa.gov.au/download/CAAPs/drome/89t_1.PDF here is a link for aeronautical survey related documents http://www.ngs.noaa.gov/AERO/aerospecs.htm#FAA405 < these are the surveys that must be made in order to get FAA approval for an airport > there are photographs of several different 'conforming types' linked at the bottom of this page HTH Norman ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

That would also let us > custom-design unusual configurations. The directional lighting is based on environment mapping so the input you feed it is 'static', i.e. there's no animation. You need a texture map that specified the light color relative to view angle. The direction a light is pointing (i.e. a normal.) Plus a slightly clever mechanism to draw a point that isn't visible from behind. (Which keeps us in the bounds of defined environment mapping behavior.) Then you turn on environment mapping/automatic texture coordinate generate for drawing lights and set the polygon drawing mode to GL_POINT to allow the one side point trick to work and draw the point. The system automatically calculates a texture coordinate (or position in the texture map) based on your view angle relative to the specified normal. If you are looking at the point dead in line with the normal, you will get the center of the texture map. It's a bit of work to get there, but is a nice effect in the end ... although vasi/papi is not working out as well as I had hoped. It could be I'm doing something wrong, or could be that there is something I could do differntly to make it work correctly? I might punt on that for the moment.

It's an astonishingly simple device. Basically, it's a box with a bright white interior. At one end is a lens. At the other (on the focal plane of the lens) is a white card painted red on the top and white on the bottom. Along the sides of the box are flourescent light tubes. ++ Red#/\ # | | Lens ~ | | Wht~\/ +-- + ==light=== So when you look through the lens, you see a singularity image (i.e. infinite magnification) of whatever you're looking at on the back card. If you're below the centerline, you see the red side. If you're above, you see the white. The box is mounted on a pair of sturdy concrete poles, and is tilted up at the glideslope angle. Basically, Curt's approach seems exactly right. The image of the thing depends entirely on direction to the viewer. There are no moving parts at all.

[Flightgear-devel] VASI lights in new sceenery
Curt, I just noticed that one of the KADW 01L VASI lights is underground and invisible. This is probably not the only instance, though it is the only on I have seen. Perhaps there should be a strip of truly flat land wide enough to encompass the VASI and PAPI lights, and anything else that lives close to the ground next to runways for that matter.
