Runway Centerline Extensions
The Apollo handheld GPS receiver includes
an automatic procedure to insert the runway
end point and a point four nautical miles out
on the runway centerline extension into any
route. These two points can be used to line up
the airplane with the runway centerline and
give distance information to the runway end.
These are NOT published approaches and do
not take into consideration any terrain or
obstacle
clearance. These extensions are
provided for many runways around the world.
