But now seriously chaps, help me out here regarding this “Direct to” a waypoint in my flight plan business:
So here I am bumbling along to waypoint AHN. If I would like to proceed directly to TIGNA is my only option to hit the “Direct to” button, and then manually input TIGNA (which takes some time using the knobs), or is there a way to select the waypoint in the flight plan and somehow activate a Direct to that waypoint?
