Q. Do I have to update my GPS / FMS NavData every cycle?
When should I update my NavData card? Is there an effective date?
For your convenience, we make our updates available 7 to 10 days prior to the effective date. Pilots using most GPS units will want to load new data updates as close as possible to the effective date. However, we don't recommend that you load and update your NavData card before it becomes effective. Attempting to use new or revised data prior to its effective date can cause problems for ATC and can impact flight safety.
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. With non-dual cycle FMS units, it's an operation decision as to when to update to the current cycle of data. ARINC 424 doesn't specify an effective time.
Q. Where can I view a schedule of the NavData and terminal chart update cycles? When does NavData update, and what is the effectivity schedule?
