VOR to VOR navigation question

So how was flying across huge oceans handled? Plan-G shows the nearest VORs to be ~1000nm apart in Atlantic!!  They dead reckoned a heading for over 800nm?

 You also need to plan your route so that you'll be able to maintain VOR reception. In the one image on page 1 where the changeover point was mentioned you'll also see the MEA.. The MEA is there to ensure you will have adequate signal coverage between the 2 stations.

Of course VOR's aren't used in Oceanic crossings. That's why back in the day you had a navigator. Before INS, RNAV, GPS etc there was LORAN or SEL NAV and even sextants!

This reminds me of my experience a few years ago with VORs.  I had carefully studied the FSX lesson on VORs, but no matter how much I tried, I couldn't pass the test (there's a part of that test that still makes no sense to me).  Finally, I decided to just try flying to a small rural airport in FSX using VORs exclusively.  I figured "the proof's in the pudding", this navigational flight would show whether or not I had a basic understanding of VORs. 

 

After flying for a couple of hours, I was supposed to be at my destination - but there was NO airport to be found, nowhere.  I looked in every direction, but nothing.  Oh no!

 

Then I discovered that the airport was directly beneath me, where I couldn't see it.    : )

For the most part, yes. navigators on overwater flights had the luxury of being able to tune into radio stations, and use their fixes to pinpoint the flight's position; something that isn't possible (to some degree) in FlightSim.

 

If you go back to the days of the PanAm Clippers, they used a sextant to shoot star sightings and plotted their positions that way. There are Gauges available to simulate a sextant, with the ability to 'shoot' stars in order to plot your location.

 

Take a peek at the odyssey of the Pacific Clipper:

The first around the world flight by a Commercial aircraft, using only a sextant, rudimentary maps from a World Atlas, under radio silence,

and by the seat of their pants.
