ANNOUNCEMENT
DATA FORMAT CHANGE
A revision will be made August 13, 2003 to the Navigational Aid Data
section on the Universal Data Delivery Format (UDDF) in order to report
additional information for ILS marker beacon antennas. The point on the
the runway centerline extended nearest to the indicated ILS marker beacon
antenna will now be reported. The distance between the NAVAID and its
associated runway centerline point (CLPT), along with the offset direction
L (LEFT) OR R (RIGHT) relative to an observer facing forward in a landing
aircraft, will be reported in the "NAVAID OFFSET DISTANCE" column.
The distance between the NAVAID's runway centerline point (CLPT) and the
runway approach end will be reported in the "NAVAID ALONG CENTERLINE
DISTANCE" column. Note that the distance between the NAVAID and runway
approach end will continue to be provided.
