[Flightgear-users] instrument approaches in FG
My query is mostly related to navigation, but since I'm using FG (not currently a reality pilot), I'll ask here. I'd like to practice instrument approaches in IMC. At this time situational awareness is pretty good using VORs, and I do a nice ILS approach/landing down to minimums (no high crosswinds!) flying the needles. Is it possible to do GPS or VOR/DME approaches in flightgear? For former I'm guessing no, although not sure since there is the lat/lon on heads-up display. How about VOR/DME? As I understand, these are done by intercepting a VOR radial, flying over the VOR, and then timing to calculate distance. Not sure how one decends glideslope in real flying situations. How does one approach/decend using NDB. The field near me (KDAW; Skyhaven; Rochester, NH) has a NDB approach: http://www.airnav.com/depart?http://204.108.4.16/d-tpp/0501/05978N33.PDF what happens in IMC after flying the to the NDB? I plan to read more about IMC flying soon, and just want to maximize learning potential. I'm considering flight school at this time :-) Mike __ Do You Yahoo!? Tired of spam? Yahoo!

I'm using an via chipset mobo too but I compile the via chipset support into the kernel as opposed to agpgart support, which I compile as a module. I dunno if this gets you anywhere but it might be worth trying. Do you have POSIX shared memory support enabled? This comes under Virtual memory filesystem support (former shm fs). I believe this is required for the ATI drivers.

Re: [Flightgear-users] instrument approaches in FG
Upon further review, I seem to understand the NDB approach, and the AP waypoint GUI accepts GPS waypoints . Regarding these approaches, from what I can tell, it's all about the MDA and MAP! A message on the developers group from Feb 2003 mentions a DME radio, but I can't seem to figure out where this is on the radio stack.

A message on the developers group from Feb 2003 mentions a DME radio, but I can't seem to figure out where this is on the radio stack. DME has it's own frequency, but it is normally slaved to the VOR receiver's channel. A VORTAC has a VOR transmitter and a DME transponder at the same location (also has a TACAN, but that's for military use only.) So, if you set the NAV receiver for a nearby VORTAC, the DME will automatically pick up the associated DME transponder. (It is possible for the DME to lock onto a more distant DME transponder on the same channel, but that is a rarity except at high altitude.) In aircraft that have remote DME indicators, there is no DME radio. It is a hidden black box, slaved to the NAV channel, and readion distance on the remote indicator dial. On some older aircraft, there actually was a DME box, with the distance indicator, as well as some controls and a light that indicated it was receiving a response from a transponder.

Re: [Flightgear-users] help with ATI fglrx
Hello everyone !! Josh your problem is coming from the module owner as you can see in the lsmod listing the owner of the module ( to be read the father of process in linux ) has the owner id : 7 ... what you have to do is edit the startup config. file so the module is inserted at start-up with the owner id 0(root) ... Also if this is not working it will be usefull if I can see the .config file from kernel menuconfig. It could be the DRI suport from the kernel. Send us the file ( it should have around 50Kb). Good Luck !!! = Stefan Palade __ Celebrate Yahoo!'s 10th Birthday! Yahoo!
