Returns whether a unit is currently riding a flight path (taxi). Valid for any unit in the player's area of interest, but generally useful only for player -- taxi flights move quickly, so a taxi-riding unit visible to the player will not remain visible for very long.
See also Unit functions, Taxi/Flight functions.
Signature:
onTaxi = UnitOnTaxi("unit")
Arguments:
