I've added a new command, property-randomize. It sets a random value
within a range specified by the user, like this:
<binding>
<command>property-randomize</command>
<property>/environment/pressure-sea-level-inhg</property>
<min>27.92</min>
<max>31.92</max>
</binding>
Just for fun, I've added a couple of entries to the menu to
demonstrate the new command (well, the first one has real training
applications).
1. Location/Random Attitude
---------------------------
The three most dreaded words for any flying student are "cover your
eyes" -- they mean that the instructor is about the put the airplane
into an unusual attitude (often a spiral or a stall), and you'll have
a couple of seconds to open your eyes, figure out what's wrong, and
fix it as soon as she or he shouts "RECOVER!" It's fun in VMC, but
it's a blast under the hood.
Now FlightGear has its own Virtual Sadistic Instructor to do this for
you. Just select the Location/Random Attitude menu entry, and
FlightGear will instantly put the plane into a ridiculous attitude,
no eye-covering required. For extra fun, try it in IMC 500 feet above
the ground:
fgfs --altitude=500 --vc=110 --visibility=50
Then, as soon as the program starts, select the "Random Attitude"
entry and try to recover. Once you can see the ground, it's probably
too late.
2. Weather/Random Weather
-------------------------
Until now, in FlightGear every day has been a good flying day. Not
any more -- select Weather/Random Weather and you can get good or
crappy weather any day, just like in real life.
Some day we'll do a good job of this; for now, it just sets some
random and not always consistent values -- for example, you might get
heavy fog with a 40 degC dewpoint spread, or -40 degC at the equator.
We'll work on it (or perhaps climate change will catch up with us
first).
All the best,
David
