Hi Chen,

Well I've been playing around with the software and done just as you say and it still fails. Being in the software testing game I've been trying to reproduce the issue in a reliable way.

It turns out that I had placed my position for the launch site according to what the Google Maps overlay showed... The google maps overlay however for this location are out by 10-20 meters and what is displayed in the image as the top of a hill is half way down the back according to the SRTM files... :-(
So when I launched it flew straight into the hill.

Of course I'm assuming this is an issue with the Google maps overlay and not something else...

Hi there

 I had the same problem before as well

Anyway, you need to jump to block of "take-off" , then press the lunch.
Now the simulation should show the aircraft is in the flight.

I'm having trouble making a flight plan that actually works in the sim.
I've downloaded the latest source and built, srtm files for Australia.
I've copied the basic.xml flight plan and changed only the the

<flight_plan alt="300" ground_alt="200" lat0="-36.778810"
lon0="149.696277" max_dist_from_home="1500" name="Basic"
  <waypoint alt="300.0" name="AF" x="177.4" y="45.1"/>
  <waypoint alt="200.0" name="TD" x="28.8" y="57.0"/>

When I load the example project with these changes and launch the A/C
very quickly stops. (crashes)
I've tried changing the ground_alt and alt to real values (150) and
always get the same result.

What am I doing wrong?
