If you plotted a course to a target say 300 miles away in France
(assume a straight line) how close would you expect to be on average
at the end of the estimated time of flight to target? Assume no nav
aids or fixes.
Just take off on a given course for a given time.
Art probably would be the better guy to ask than me, but in my simple minded
pilot's soul, if I'd plotted the course acccurately and had cranked in the
correct variation and deviation, I'd have been pretty close to on the mark
assuming a day in which the air over the course was completely still. Was
it a trick question?
OTOH, I used to be pretty good at following railroad tracks when my other
nav skills abandoned me.

Also known as IFR (I follow roads) flying.
In the late 1970s or early 1980s "Stars and Stripes," European
edition, had a cartoon of a helicopter hovering low to read a road sign.

I know of cases of pilots pre ww2 flying low and slow to read railway
station names too.
The question i suppose is how close to your target will flying the
original course with no deviation get you, given the effects of wind
and weather.

With no compass or barometer, flying in a fog,
using only the inner ear for guidance, I'd be
screwed.
Try it yourself, go into a large room, set a course
to a point on the otherside, have someone turn-off
all the lights, then walk in pitch black to the light
switch, see how close you get.
With a compass and altimeter, I'd be very lucky to
get within 10 miles, unless I was going from
London to the Eiffel Tower, oops, did the Parisians
really want that thing sticking up :-).

I remember driving I 35 in 70s, every once in a while you'd see a
general aviation type offset a hundred feet or so from the road flying
along at 1500 feet. One way to make sure you hit Dallas.

I seem to remember British Intelligence supposedly asked for maps,
tourist photos, from the Continent during WWII. We seem to forget how
mapping used to be a big deal. Dad had maps from SAC marked uncharted
territory of the Canadian North. God knows what he had for the Soviet
Union. This was before Powers was shot down.

When I lived in LA, there was a mapmaker, put out a street atlas of
LA, forgot the name of the publisher. Their maps were copyrighted,
they went out and checked locations they had on them. One of the
newspaper stories they said they put one ficticious street location on
their maps so if somebody copied their maps they'd be able to prove
illegal usage. Usually some small street somewhere with some name that
didn't exist. They updated them yearly and it was a big deal for
delivery guys, all that to buy updated books from them of all the
streets in LA.

I remember we wanted a map of Edwards, one that had all the sensor
sites, emergency runways, all that. There were DMA charts, aero stuff,
but we wanted a good base map of the range and adjacent area. Finally
got one after years from DMAA, all the range rats, old timers went
over it, found errors on it. Stuff that wasn't there, stuff they
missed. I doubt they ever updated it

The old C-130 flight simulator building, building 424, on Eglin AFB was never on any map I ever saw between 1980 when the flight simulator was there and 1994 when the building was being used for avionics. Some less than ethical people who worked there would order pizza knowing the "30 minutes or it's free" always meant free pizza. The pizza joints eventually caught wise.
