Data for known obstacles such as towers, buildings, antennas, etc. is
contained on the same data card as the terrain and airport data.
Presently, there are some 70,000-plus obstacles in the database, but
they are all in the area of North America. As more reliable information
becomes available, Honeywell will expand the capability to provide alert-
ing and warning for obstacles in other areas of the world.
Obstacles in the database are those known obstacles more than 100
feet AGL, so obstacles of lower height will not produce GA-EGPWS
“Obstacle” alerts or warnings. However, terrain elevations are “rounded”
up to the next 100 feet, so alerting and warning protection is generally
available for known obstacles that are less than 100 feet AGL.
