These hardware recommendations for FlightGear are based on community feedback, be sure to consult other sources before making serious decisions regarding computer hardware. The performance of FlightGear depends on three main components in your computer: the CPU (processor), which makes all the computations; the graphics card, which renders the visual aspect of FlightGear, and RAM (also known.

Changing it to the following fixed it. var onGround = getprop('gear/gear/wow'). getprop('gear/gear1/wow'). getprop('gear/gear2/wow'); Same cargoopporations.nas file, everything else being the same, all other references to all other aircraft conditions and geo calls all worked except this.

All that changed was moving it from aircraft domain to addon domain. This is some kind of ordering issue I think - it sounds as if props.globals was not initialised when the addon was started.

The JSBsim file I sent is enough to to load the Sim and test the issue via a listener. It does not do anything else, except allow easy reproduction of the issue.

Sounds like a lot. Not sure I'll sucessfully write the actualtest.

I may need hints or an example to follow.I'm also wondering if the problem can be found just testing the propertytree, or is it JSBSim's way of using the property tree that's the issue.If the workaround is in git already, and I actually wrote a test that onewould expect to fail on this issue, would the workaround cause the test topass?

In other words, with two clones of the main flightgear git, does the order of pulls and pushes between the three matter?Keep your forks, but just regularly keep them up to date. You can do thisas follows:- Clone your fork locally.- Use 'git remote' to rename your remote to say 'u-callahanpa-flightgear'.- Use 'git remote' to add the original FG repository as'flightgear-flightgear'.- Then run:$ git fetch -all$ git checkout next$ git merge flightgear-flightgear/next$ git pushYou are now up to date. Your 'next' branches should only ever containmerges from 'flightgear-flightgear/next'.

They must remain clean. Alldevelopment should be on branches.Regards,Edward.

A missing property should definitely not cause a crash, IMO. Can you give a minimal setup to reproduce, and we can test-ify it and ideally make things more robust?Take the An-24 at the previous revision, start fgfs with it.

I'm game. Who else wants to work on this as part of a group? Don't be shy. Meantime I'm off to take a closer look at Josh's result and anything said recently about jsbsim on flightgear-devel.I forgot to mention one commit as part of this thread:To start diving strait into the test suite code, firstly copy what hasbeen done in this commit:Just modify all names for a JSBSim test (or any other test fixture youwant to code). You should then be able to compile and check that yournew testDummy test passes as expected. You can then slowly build upfrom this basic infrastructure as you learn the fgfs internals, c,and git skills required for implementing your test on your fork's newdevelopment branch:)Regards,Edward.

Scene it lights camera action xbox 360. Founded in 1997, FlightGear is developed by a worldwide group of volunteers, brought together by a shared ambition to create the most realistic flight simulator possible that is free to use, modify and distribute. FlightGear is used all over the world by desktop flight simulator enthusiasts, for research in universities and for interactive exhibits in museums.FlightGear features more than 400 aircraft, a worldwide scenery database, a multi-player environment, detailed sky modelling, a flexible and open aircraft modelling system, varied networking options, multiple display support, a powerful scripting language and an open architecture. Best of all, being open-source, the simulator is owned by the community and everyone is encouraged to contribute. You’ve seen hiring tests before. Maybe they’re a series of questions your boss came up with, maybe they’re a list of riddles that a qualified candidate should have no problem solving.

Whatever the case, you know deep down they don’t work. Knowing that doesn’t fix your problem though. As a hiring professional, you need an efficient way to screen candidates effectively, easily, and correctly. That’s where WonScore by Wonderlic comes in. Backed by extensive scientific I/O research, the WonScore assessment analyzes three crucial components of a candidate: cognitive ability, personality, and motivation. Using this data, we ensure that you as the employer are hiring the very most qualified person for your position and your team.

You’re able to access all of the results, which boil down to one score you can compare based on your needs. It’s quick, easy, painless, and most importantly it works.
