Shouldn't this be too - before it gets left languishing on the shelf? I would be happy to see it in the FlightGear/CVS. The structure is such that the DualControl subdirectory contains the generic/aircraft independent mechanisms and parts which could be put outside the c172p-dual-control aircraft directory (with adjustment of some paths). At this stage it might be better to keep it all in one directory, though.

Re: [Flightgear-devel] [ANN] dual control c172p prototype
Just some news: I added a second basic T for the copilot. I'm not sure if that is common in this type of aircraft, but it is nice to have. And a teaser of what will soon be the splash screen :) http://www.gidenstam.org/FlightGear/misc/c172-dual-splash.jpg Csaba and I made some test flights yesterday with good results. I think we are located about about 1000km apart with the mpserver geographically in between (but I have no idea about the actual routes used :). Total network RTT probably about 100ms, feedback RTT roughly 0.5 seconds. The prototype is available here: http://www.gidenstam.org/FlightGear/misc/c172p-dual_fgfsCVS.tar.gz (See http://www.gidenstam.org/FlightGear/misc/ for updates and some other small projects.)

Not particularly common and not at all on the PA-28s AFAIK, but as you say nice to have -- One of the frustrating aspects of my flight training was the engine RPM guage being on the instructors side on the PA28-140 and the consequent parallax errors. I said 2400rpm Thats what Im doing No its not, you're revving the s off it /me moves head back a bit Ah OK Thats better, why couldn't you do that the first time? Cos it looks like 2400 rpm from here Well be more careful then meanwhile my attention has been distracted and I'm trying to remember what the the second M in 'BUMMPFFICHH' stands for Call _that_ 1000 ft ? .. looks more like 1100 going on 1150 and so on for several bumpy not-rectangular-at-all circuits And a teaser of what will soon be the splash screen :) http://www.gidenstam.org/FlightGear/misc/c172-dual-splash.jpg Csaba and I made some test flights yesterday with good results.

Re: [Flightgear-devel] [ANN] dual control c172p prototype
What would be the added value of this as opposed to hooking up two sticks to the same machine running fgfs? I'm not sure whether that will work as well under Unixes, but there is no trouble in using that on Windows machines, simply assign the axes of both sticks to the same controls. I've been running dual control setups like that for a long time now, have yet to seriously test it with FlightGear but have no trouble using it on FS9.

Meanwhile - if you are on MP we're aboard and watching you :-). In case that made you curious, I can provide a preview since my prototype has now reached a somewhat useable state. Pilot and copilot currently have shared control over aileron, elevator, rudder, throttle, mixture, elevator trim, flaps and brakes. The copilot has a limited subset of the instrumentation. The system consists of two aircraft: - The pilot uses a modified variant of the c172p from FlightGear/CVS. The pilot need to specify the callsign of the copilot (other copilots will be ignored). Note: if your designated copilot uses another aircraft than c172p-copilot some of his/her control input will still affect your aircraft.. Usage example: fgfs --aircraft=c172p-pilot --prop:/sim/remote/pilot-callsign=copilot - The copilot uses a special aircraft c172p-copilot which piggybacks on the designated pilot and captures the local control inputs. A current limitation is that only the cockpit view (ctrl-v) is jitter free. There is also a noticable delay between control inputs and effect, since they are passed via the the multiplayer protocol. The severity of this delay depend on round trip time and some other factors - the delay seems significantly longer than the round trip time itself. Since being part of a control loop most likely wasn't in the design spec. for the multiplayer protocol I think we can improve this. E.g. by allowing the pilot side to bypass the deliberate delay/interpolation of control inputs from the copilot. That said, I have flown successfully as copilot in a setup with 100-120ms round trip time between both pilot and server and copilot and server (total delay 500ms). Landing is a bit exciting in that case, though. The deliberate delay added by AIMultiplayer can be significant - I have seen (rare) 5 sec delays on my LAN - I think some unfortunate interaction during the startup of the pilot and copilot fgfs instances messed up the AIMultiplayer lag tuning. Usage example: fgfs --aircraft=c172p-copilot --prop:/sim/remote/pilot-callsign=pilot The prototype is available here: http://www.gidenstam.org/FlightGear/misc/c172p-dual_fgfsCVS.tar.gz (See http://www.gidenstam.org/FlightGear/misc/ for updates and some other small projects.) Observations/Comments: - In FlightGear/plib the fixed nearplane setting of 10ft cuts away most of the aircraft for the copilot. - The AIMultiplayer processing of incoming MP data adds a deliberate delay which sometimes seems to become excessive ( 5 sec on a LAN?). I know some extra delay is needed to make animation of MP aircraft smooth and avoid extrapolation, but it would be nice to be able to reduce or disable it for the control inputs from the copilot. A property below multiplayer[x]/controls/ in the AI/MP subtree to control this would be nice. - In the long run I think we'd want the MP system to support something similar to publish/subscribe - e.g. the properties sent from the copilot is only interesting for the pilot and the extended aircraft state sent(/published) by the pilot aircraft is only interesting to the copilot or anyone else riding in the cockpit. Currently everybody in the neighbourhood receives the data. Have fun piloting! Cheers, Anders - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.
