Updating jeppeson database
NOTE: Most FMS units are dual cycle and carry both a current and future data set.
With these units, the future effective data can be loaded at any time, and the unit will automatically switch on the effective date. Where can I view a schedule of the Nav Data and terminal chart update cycles? The most current notices and alerts for your avionics are always just a click away.
Attempting to use new or revised data prior to its effective date can cause problems for ATC and can impact flight safety. Every 28 days, there are on average more than 85,000 changes to the Nav database. Yes, there is an effective date, and Nav Data updates for GPS and FMS equipment are only good for the specific, 28-day time period indicated.For this reason, we also strongly recommend a regular update service to VFR pilots! Pilots using most GPS units will want to load new data updates as close as possible to the effective date.If you found this page by accident, we would greatly appreciate hearing from you.Any feedback regarding your experience on the Jeppesen Customer Support Portal will help us improve the quality and functionality of this service.
