Wind: compass-assisted wind calc (using nmea-compass)

[daniel.forst@…]

hi...

during long straight flights a compass(heading-sysstem)-assisted wind-calc
would be very useful in oder to get a correct wind-indication even if not
circling for a longer time or during mountain-flights where the wind may change
quite often, depending on the topology.
there are compass-heading-systems available that transmit the information to
external devices using nmea-sentences.

e.g. http://www.yachtbits.com/nasa/nmea_compass_sensor.php .

the nmea-datastream could then be multiplexed into the nmea-datastream of the
logger, vario or flarm.

a nmea-multiplexer is available at

i'm pretty sure hans or falk from the k6team would assist you if you need any
support concerning the nmea-multiplexer... just drop them a mail... they are
really nice guys a know a lot about this stuff.

if you have any questions, just contact me via email.

keep up the great work.

cheers...
