Hi, I just pushed a new instrument to "next": we now have a TCAS device. It's a new module providing aural alerts for conflicting traffic. It's also able to drive TCAS displays, since aircrafts' threat-levels are exposed to the property tree. The existing wxradar instrument is updated accordingly, and now has an option to display traffic in TCAS-style (colorful diamonds/circles showing the traffic's threat-level). The TCAS is implemented in the FG core and requires minimal performance - so should be fine even at busy airports.
And it works with AI and multiplayer traffic. As expected, AI pilots are well-trained, so they always respect TCAS advisories: when you get a "climb! climb!" alert in your cockpit, you'll also see conflicting AI planes dive to safety (or vice versa). And since you're a responsible pilot, I trust you'll also know what to do... :) There's more info on its features and installation in the wiki: http://wiki.flightgear.org/index.php/TCAS I've tried to stick as close as possible - well... reasonable :) - to the TCAS II standard. The traffic detector shouldn't be too far off. However, I've simplified the advisory code a bit. A TCAS II only provides vertical advisories (so it's either up or down...), but there's still a long list of variations and exceptions in the standard. Also, determining/predicting an optimal evasive movement for conflicting aircraft isn't always easy. Well, should be good enough for most situations as it is now. I might still add a few more advisories later - as well as improve the MP support. The TCAS and new display is already installed on the 777 now. And the cockpit is also extended with an ATC/TCAS panel (more switches!) - huge thanks to Syd Adams for another nice modeling job! A good area for test flying the TCAS is EHAM - with lots of AI traffic. Give the AI pilots a hard time by interfering with their nicely aligned approach sequence. The default TCAS voice samples in fgdata are temporary stubs only (artificial voice). Hopefully we can replace them by more realistic sound samples soon. But you can also provide custom voice samples for an aircraft (which is also possible for the GPWS now, see "GPWS" in the wiki). Hope the new instrument works for everyone (well, Hudson compiled it!). And hopefully this won't trigger a new multi-player sport (proximity flying to trigger TCAS alerts) - otherwise just use the "ignore pilot" buttons. Fly safe! cheers, Thorsten ------------------------------------------------------------------------------ Free Software Download: Index, Search & Analyze Logs and other IT data in Real-Time with Splunk.
