Must the GPS database be current to use the GPS for VFR navigation?

No, it is not required for VFR, but an outdated one is not recommended near critical airspace.

  1. Yes, it must be updated every 28 days
  2. No, there is no such VFR requirement ✔
  3. Only when flying at night

Why: Databases must be current for IFR, but there is no rule requiring updates for VFR. The AIM still warns against relying on an outdated moving map near critical airspace, and says to check waypoints on current charts.

Huh, didn't know that: The AIM says many VFR GPS receivers have no RAIM alerting, so pilots should cross-check position another way.
