Well, so much for the paperless cockpit. The FAA has issued a NOTAM warning pilots using Jeppesen NavData flight-planning information to use paper charts until the company sorts out a glitch in its database that might misrepresent the boundaries of several types of special-use and controlled airspace. "This affects a small number of NavData users," said Jeppesen spokesman Mike Pound. Pound said the company has traced 350 boundary "irregularities" in the database out of more than 20,000 listed. Pound said the false boundaries can show up on data supplied directly to owners of moving-map GPS units. The aberrations can also affect flight-planning information offered by third-party vendors that use the Jeppesen database. He said the irregularities involve the precise position of the airspace boundaries. The glitch does not affect other Jeppesen data such as navaids, intersections and waypoints. The errors do not show up on Jeppesen charts, either.
