Subject: NavData Boundary Data

A problem has been discovered in NavData Controlled Airspace, Restrictive Airspace, and FIR/UIR boundaries, which can cause a misrepresentation of the boundaries for some airspace. Do not use any of the boundaries for reference or navigation. Until further notice, please refer to information from other publications such as paper charts as your primary source for boundary information.

Jeppesen will provide further information when it is available. Until then, an entry will appear in the NavData NOTAMs beginning with the 7 MAR 03 revision, and this Alert will be posted on the Jeppesen web site (click on Aviation Resources, On-line Publications, NavData NOTAMs/Alerts).

WE STRONGLY URGE YOU TO MAKE THIS INFORMATION AVAILABLE TO APPROPRIATE CREW MEMBERS, CUSTOMERS OR OTHER USERS IMMEDIATELY!

NavData Alerts are published to advise users of significant issues in Jeppesen navigation data which may affect flight operations or safety. They are distributed to affected ARINC 424 NavData users (avionics companies and other raw data users) and airlines receiving NavData direct from Jeppesen. Alerts are not distributed by Jeppesen to individual airline, business aviation or general aviation pilots, but are available to them on the Jeppesen web site, www.jeppesen.com. Different avionics equipment and computer systems use and display NavData, and data derived from NavData, differently. Avionics users should consult with their database update service provider for definitive information on whether their system is affected by this Alert.
