Anyone want to chime in on some good contest strategies or tactics?

Get a copy of Condor soaring simulator (www.condorsoaring.com) and
start flying some races (Monday Night Soaring 7 &10pm ET Mondays -
friendly to first-timers)

Figure out how to connect your regular flying PDA to Condor. Condor
outputs GPGGA, GPRMC, and LXWP0 sentences to a COMM port, and most if
not all soaring PDA programs accept these by default. You may need a
USB-to-serial adaptor for this.

Design some short AAT and/or MAT races in Condor and fly them using
your actual PDA. You'll be surprised how hard it is to make the PDA
work for you instead of against you, and this is something you do not
want to discover in an actual contest.

IMHO Condor is by far the best way to prepare for cross-country
racing, as opposed to cross-country flying.

Just wanted to also put in a plug for Condor, with one caveat:

Do _not_ use Condor to soar your local area, or your intended contest
area. At the least you'll find it annoying because of the
inaccuracies. At worst you'll make bad decisions in real life because
you got used to referencing the terrain in Condor and try to apply it
to the real world!

Condor Soaring is awesome for developing general soaring techniques
and (as TA pointed out) working with a PDA/flight-computer. It is NOT
designed to give you ground-reference familiarity.

Well, I have actually found Condor to be quite helpful for area
familiarization, as Condor uses the same terrain database used for all
other terrain mapping programs, including Google Earth. Flying a
terrain in Condor is much more helpful to me than 'flying' it in
Google Earth or staring at a map.

However, as Noel pointed out, no terrain database is entirely
accurate, and location/elevation errors of hundreds of meters are
common, so assuming that a ridge line goes just so, or that a mountain
pass is just this high, could lead to some very embarrassing moments
in real life. Also, thermals in Condor aren't always where you would
find them in real life, although thermals do tend to favor high ground
as expected. In flat terrain, thermals are distributed more or less
randomly, and don't correspond to infrastructure features like road,
towns, lakes, etc.

NEGATIVE. This is NOT TRUE. Some people use the NASA "SRTM" data for
terrain elevation; but there are different resolutions for that data
that can provide different levels of accuracy. And Condor maps are
all user-created and not necessarily based on real-world locations.
It is totally up to the map's creator to define the terrain and the
scenery. Satellite photos _are_ used for some maps; but others are
semi-random repeating patterns of texture & color to make lowlands
look lush and high ground look rocky - with no regard for the real
world.

Condor is the product of just 2 people. And it is AMAZING for the
small team that produces it. But the maps are not like MS Flight
Simulator where a large dedicated team of people has spent years
poring over the entire world and building it up as accurately as
possible. Some map-makers are obsessive and realistic; other map-
makers provide scenery that is inaccurate or is a wholly fantastic
setting (and there's nothing wrong with that).

As Frank points out, thermals are not always accurately placed in
Condor, either. The map files have hidden values that tell Condor
what probability to assign to a thermal popping up in any given
location... Those hidden values are specified by the map-maker and are
not necessarily tied to any real-world data. Condor tries to simulate
the effects of wind and terrain, but it uses those hidden values as
its primary guide to thermal generation. So again, if the map-maker
is obsessive and makes the house thermal spot (in real life) a likely
place for thermals to form in Condor - then its probably fairly
accurate.

Runways and buildings are the same way. Its not based on exact real-
world data; its based on whatever the map-maker says. And with dozens
of small/outlying airfields in most Condor maps, you can bet that a
certain percentage of them bear no resemblance to their real-world
counterparts. Heck, some of them don't even have the runway pointing
in the correct direction.

NOW, having said all of that - let me make it clear: CONDOR IS AN
AWESOME PROGRAM. Any pilot who wants to work on his/her cross-country
soaring or racing skills should have this simulator and use it. But
use it to develop your sense of timing and flying skills - do NOT try
to use it as a guide for what the "real world" will look like when you
get there.

Enjoy,
