Re: [Flightgear-devel] best way to remotely control flight gear?
* Eli Jordan -- Tuesday 14 July 2009: as far as I could see the route manager only allows for pre set waypoints, such as airports, i was hoping to be able to input co-ordinates (latitude and longitude) and have the auto pilot fly between these. In telnet just type set /autopilot/route-manager/input -123.456,37.89 to append this waypoint to the list at runtime. That's lon,lat. (Maybe we should swap those?) You can also demand a particular altitude: set /autopilot/route-manager/input -123.456,37...@8000 Possible formats are: (airport|fix|nav|lon,lat)[...@alt] -- e.g. k...@900 There are commands available for clearing the list, removing entries, etc. @clear ... clear route @pop ... remove first entry @delete3 ... delete 4th entry @insert2:k...@900 ... insert k...@900 as 3rd entry k...@900 ... append k...@900 For example set /autopilot/route-manager/input @clear This works also from the property browser, or via Nasal etc. The route manager dialog uses the same interface. Of course, you have to use an autopilot which takes the waypoints from the route manager if you want your aircraft flown through all the points. The default AP does this. m. -- Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!

[Flightgear-devel] best way to remotely control flight gear?
Hi I am new to flight gear, but am using it in a multiple flight vehicle simulation system for my thesis, this system will be used to research aerial search patterns. To do this I need to be able to control flight gear from the search algorithm, running on a separate machine. I was wondering what would be the best approach to achieve this? I have had a look on the web site/wiki and found out about the telnet interface to the property tree (also, is there info on the syntax of each variable in the property tree?) and thought that the route manager accessed through telnet would be able to solve my problems, but as far as I could see the route manager only allows for pre set waypoints, such as airports, i was hoping to be able to input co-ordinates (latitude and longitude) and have the auto pilot fly between these.

Any help would be greatly appreciated!! At a lower level, the FlightGear waypoint system can handle any arbitrary latitude and longitude and altitude. However, something that might work better for you (?) would be to just set up a basic autopilot that can hold a commanded heading, altitude, speed, etc. and then monitor the flight location from the remote search algorithm and pass heading updates to the autopilot. The autopilot target values are all stored in the property system, so it's really straightforward to change them from a remote application using the telnet interface. And likewise you could monitor aircraft location through the same interface.

Any help would be greatly appreciated!! ThanksEli I believe the GPS sub-system may be able to help you, but failing that writing your own FCS using Nasal isn't too difficult (although the development and testing may be time consuming). The Nasal Geo sub-system includes a number of very useful functions that can be used to direct a custom FCS and autopilot combination to fly between a series of lat and lon coordinates and even perform automated take-offs and landings. As I have said above though, tuning the custom configuration to work well with the particular FDM you use can be very time consuming. One thing to be aware of when using the Nasal Geo functions is that some of them need the relevant scenery tile to be loaded into the scenery cache before it can be interrogated, so while flying between coordinates at an absolute altitude is not a problem, setting up a relative altitude (agl) flightpath or getting runway locations and orientation cannot be done until the relevant scenery tile is loaded into the scenery cache. Another thing to bear in mind is that no consideration is given to backwards compatibility in FG development, so for the period of your thesis I would avoid tracking the cvs version of FG and either use one of the stable versions or stick with a single cvs snapshot; you're quite likely to find your work broken by subsequent development code changes if you try to keep up to date with cvs. LeeE -- Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!
