In the 1960s/70s there was still a lot of WW2 expertise around in the Victor Tanker Force, these guys taught us from their experience about situational awareness.
OK, in mainly two dimensions.
We had a single G4B compass system which could precess at 15 degrees an hour with NO attendant bells or whistles. Only indication was a small window
on the repeater which should alternate between Dot and Cross, if working correctly. You tried to monitor this amongst all your activity.
If you were on a Transatlantic flight to the well known Paradise of Goose Bay, you would normally hit the Ocean at local noon. The Sun was due South of you
and your speed generally matched that of the Sun's passage over the Earth. So as you set off from overhead Stornoway the Captain (LH seat pilot) would
draw a Chinagraph (wax pencil) Circle around the Sun and alert the Navigator if it came out of the circle. We did ,of course check the Main and Standby Compasses
every 15 mins.
This gave me a great awareness of direction, which I still find usefull to this day.
