But if I say UL423 - how do you instantly check and confirm that UL423 equates to waypoints Alpha, Echo, Oscar etc?
As part of our preflight checks, we verify the nav database accuracy, so it should match. Furthermore, with the introduction of electronic charts, if it's already plotted on the chart, the route will be highlighted.
That being said, you're in charge of the frequency. If you need us to verify fix by fix, we'll have no problem with that. Thanks for taking the time to ask though!
