When you set up a flight plan with a departure and destination airport selected, you can turn on approach guides by choosing active or all. The approach guides are green “follow me” boxes that get you to your destination by following them. I know I can find out on my own but it is late and will not be able to fly for a few days ( work gets in the way all the time) what is the differences between active and all. I have been using all for now. Also what are the yellow ones called and where do I find them under so I can turn them off?
