What is a consideration when using a hand-held GPS for VFR navigation?
A
Position accuracy may degrade without notification.✓ Correct Answer
B
RAIM capability will be maintained for entire flight.
C
Waypoints will still be accurate even if database is not current.
Explanation
AIM 1-1-17 cautions that many VFR and handheld GPS receivers have no RAIM, so position accuracy can degrade without any warning to the pilot, and an out-of-date database may contain waypoints that have moved or no longer exist. That is why VFR GPS use should be cross-checked with pilotage or other navigation.
