A destination runway selection method, system and apparatus for use with a
Terrain Awareness and Warning System ("TAWS"). The method involves
determining upon which of a number of candidate runways an aircraft is
most likely to land so that appropriate Required Terrain Clearance
("RTC") values and other alert thresholds may be referenced. According to
a first aspect of the method, a destination airport is initially selected
from among candidate airports. According to a second aspect of the
method, a destination runway is selected from among the candidate runways
at the destination airport. In one particular embodiment of the
invention, the candidate runway is selected solely on the basis of
distance calculations between the runway and the aircraft.
