Now it's happened.
Like me, you've completely converted to electronic charts on some tablet device the mention of whose name would trigger a massive influx of spam. I try to keep a WAC chart handy but you know how that goes.
But now you've had a navigation failure of some kind, and it's time to keep a dead-reckoning log.
If you're like me, you've been keeing some kind of navigation log all along, especially for a longer flight. I wrote a while ago about one airline's practice, and that's not the only carrier whose captains write out nav logs. I emulate it.
My protocol seems complex but with a little practice it's quite easy.
- Go to your favorite flight planner. Plan. Make a screen capture of the nav log (on my tablet, that involves pressing POWER and HOME simultaneously;
- Open a productivity app like uPad and import the screen capture;
- Use uPad (or whatever) to annotate the nav log.
- Use your favorite tablet nav program and enter your flight plan;
- Take a screen capture;
- Open the screen capture in uPad (or whatever) and keep track of where you are.
