I have been thinking of a way to introduce some navigation error when simulating Oceanic crossings in old school aircraft (ie pre INS and GPS). X-Plane gives you a Lat/Long readout but it is very precise, which is not what I’m looking for. The perfect solution would be to use celestial navigation coupled with dead reckoning. So, I’m thinking a good compromise will be to add error to the charts by plotting by hand on somewhat wide scale maps… I came up with the following by grabbing maps from the JeppFD app, and then annotating the lines of Latitude and Longitude.
My plan is to plot my position on these charts with my Apple Pencil, which should introduce plenty of ‘fudge factor’ when it comes to making course corrections. If I decide to route via PLCH, the legs will be shorter, but PLCH is not a very big island to find in a massive ocean.
Another thing I am considering is to only allow myself a position fix (aka looking at X-Plane’s Lat/Long readout) if the sky above me is clear enough to see either the Sun or the stars. I will be using FSGRW, which evidently gives a pretty decent representation of weather over the oceans. Routine fixes will be taken (weather permitting) at planned ETE’s over each 5º line of Longitude on the San Francisco to Honolulu leg, and each 5º line of Latitude on the Honolulu to Pago Pago (or PLCH)…
I think I’m almost ready to start out on the trip now.
