Multiple Approaches
Even after a couple hundred hours behind my Garmin GTN 650, there are still things I struggle to do properly. Chief among those is flying multiple approaches. Sure, we mostly have to do that in practice, but if you miss at a busy airport or the winds change after youve set up, you might find yourself needing to plug in that second approach, or third. If you were like me, youd get things hopelessly bollixed up before you just cleared the flight plan and started over.
