Every Day A Blue Day

A glimpse of the future, nightmare or dream?

Where will in-cockpit graphical display of fellow competitors lead us?  This 
debate must be opened before it is too late to influence what our 
competitions may be like in a few years.

Will new technology change gliding competition tactics and make "every day 
like a blue day" always try to start late and use the gaggles.

Currently available cockpit displays displaying other competitors situations 
are in their infancy both in the range they can "see" ahead and the 
information they display.
FLARM can give detailed real-time information on aircraft within a 3-10km 
radius - this is useful for keeping tabs nearby competitors but once Mode-S 
is mandatory or widely used details of gliders possibly up to a 50km radius 
will be readily available. ADS-B receiver boxes are already available to 
pull in MODE-S generated signals and deliver them to LX instruments and 
other gliding displays but unlike FLARM there is no stealth mode to enable 
pilots to make their own flights without being watched by anyone who has the 
technology.

Extremely large, high resolution, good daylight readable displays are 
already available, newly developed tactical software will provide a pilot 
with detailed and relevant information about fellow competitors and gaggles. 
There is no technological barrier to this happening, it is just a 
programming exercise that will become refined and more targeted so that 
within a couple of years pilots will have full positional / performance 
awareness of any group of competitors they are interested in.


You will never loose track of the gaggle again
You will be aware of gaggles / gliders around the start
You will be alerted to gaggles / gliders climbing well
You will "see" gliders ahead at all times and how well they are doing.
You will see your current task performance relative to your competitors
You will see all final glides and be able to compare best routes back to the 
airfield.
Etc. Etc. - and there will be a lot of "Etc."



Technology will give everyone 40/20 vision
All this information can be monitored by the "Team" on the ground and key 
tactical possibilities can be analysed by ground based software and 
experienced coaches. If your "Team" has the resources and a good radio you 
can take critical decisions together or allow yourself to be guided through 
all the critical parts of the flight.

The questions we must ask ourselves.

Will the new technology actually be taken up and used by competitors and 
teams?

Will it really be possible to use it effectively?

Will it make our competitions fairer and more fun?

Will it lead to a new generation of pilots who win by using others not by 
their own flights?

If the answers are positive then we must consider whether this is what we 
want.


One very likely outcome is to intensify gaggling to an extent where points 
spread among the top performers will be much closer and the tactics used to 
gain that small advantage will be very, very similar to those used when 
competing on a blue day.


Should the IGC be considering the impact ?
If the current IGC competition rules remain unchanged then it is very 
possible that when Mode-S is made mandatory or widely adopted it will be the 
last piece in the technological jigsaw that will profoundly change the 
nature of gliding competitions. It is a technological development that 
should be fully discussed now at National and International level.

In 2010 the BGA competitions committee introduced a rule to restrict the use 
of in cockpit display of fellow competitors situational information, the 
wording is as follows...

EXTERNAL AIDS

All data transmission between competitors or between them and the ground is 
prohibited, except as required by the organisers, or for safety purposes or 
for anti-collision warning.
Flarm devices shall be set to "Stealth" mode or equivalent setting (known as 
Privacy Mode in some LX Navigation products) for the duration of the 
competition. Other types of devices that are able to receive and decode 
Flarm or other positional data radio transmissions without respecting Flarm 
Stealth data limiting protocol must not be used or carried in the glider



Should we take the potential change seriously and should the IGC be 
considering a similar inclusion into Annex A?



Kind regards

and All the best for soaring in 2011.
