What if instead, the normal tx mode was to only broadcast lat. Then if

Wouldn't work - a near potential collision along the other axis wouldn't
be spotted unti very late. It could also needlessly interfere with non-
glider traffic's collision avoidance. Outside the USA FLARM is commonly
used by microlites, hang-gliders and SAR aircraft.
