[Flightgear-devel] Sending flight dynamics data to serial port

2003-03-06 Thread Tim Jelliffe
Hi all, First a bit of background to this request: I am just starting off a thesis project for my engineering degree, with the task of building a cockpit mockup of a single engine light aircraft that my university has designed. Something in the same sort of class as a cessna 172. The aim

Quoth Darrell Walisser: There is a fairly well-known and officially unresolved inefficiency in the rendering of small vertex arrays that is particularly painful on Mac OS X. Thank you for the reference. I was aware of this and thought I had checked against the right patches, but apparently

Hi guys! Maybe you can help me to solve this problem I have 3 channels Flightgear on linuxandFDM computer on windows I need to write a program to wakeup and shutdown IGs. Wakeup is simple you have to setup wake-on-lan and send magic packet and have to autologin But how to implement remote

You could have the IGs be always on. By that I mean when the computer boots, it immediately starts up the FG IG and it is always running and waiting for packets from the FDM computer. Another approach I've seen is a front end GUI that runs on the operator station. It talks to daemons on each

This is probably obvious, but according to my study materials for the instrument rating, the efficiency of a jet engine depends on the temperature differential between its combustion and the outside air temperature -- that's why jets are very efficient flying near the tropopause at around

Has anyone looked at (or at least confirmed) the panel ASI and NAV problems? I've just found another one -- on aircraft on which the ASI works, the HUD and ASI readout for IAS don't match -- it seems that the panel ASI gets multiplied by the IAS/TAS ratio twice. I assume of course that the HUD
