After a discussion on irc://irc.flightgear.org/#flightgear and reading an old thread http://www.google.com/search?q=+site:www.mail-archive.com+%22stall+horn I think that a patch like the following would be advisable. It turns the stall horn off on ground if all wheels are on ground and the wind speed is below 10 kt (arbitrary number). Under these conditions one would assume that the low pressure conditions for the sensor are not fulfilled. (Rationale: the whining stall horn on parked/stopped aircrafts is reportedly not realistic and pretty annoying, too. :-)
