Introduction

FlightGear (http://www.flightgear.org) is an open source flight simulator that is even used in flight schools to train basic maneuvers, radio communication and navigation tasks. It is available for windows, mac and linux.

In this article I want to introduce my latest development of the Flying-Cat, a series of Hot Air Balloons.

Bug Fixes

By starting the simulation the decision height indicator gives a warning signal.
I fixed it by adding a setlistener:

setprop("/sim/signals/fdm-ready", 0);
var fdmready = maketimer(3, func {
if (getprop ("/sim/time/elapsed-sec") > 10 )
setprop("/sim/signals/fdm-ready", 1);
});
fdmready.start();

with a new property

< int type="int" n="8" alias="/sim/signals/fdm-ready" />

and in the sound file this property is checked.

< condition>
< and>
< less-than>
< property>/position/ground-altitude< /property>
< property>/instrumentation/altimeter/decision-height< /property>
< /less-than>
< equals>
< property>sim/multiplay/generic/int[8]< /property>
< value>1< /value>
< /equals>
< /and>
< /condition>

New Features

A new 3D model of a penguin is added. With full animation of deformation of the balloon depending on temperature and pressure.
