waypoints and fixes
Having been retired for more time than I care to admit, just a thought....whilst flying on active route 1 , is it not possible to put in the fix page, any 5 letter waypoint ? Then at the desired "moment", a quick Heading Select around towards ones "fix " turns the aircraft towards the fix and then , having made the big turn to new desired route, time enough to build up ones new route, altho' perhaps not enough time as the plane appears to pass the first fix/waypoint and then turn hard back towards the next airway waypoint....assuming the flight paths shown initially are correct! Thus no need to construct Route 2 at all......
