How long before /G required for IFR?

And yet if you suggest to
another pilot that you could get to "so-and-so" intersection (which is
the
intersection of two airways that you're not currently on) from here by
taking a 200 heading until you hit the airway, then turning down along
the
airway until you hit the intersection, and they look at you like you've
grown an extra horn on your head.

Why don't pilots do approximate bearings like that? The only thing I've
seen close to that is when ATC will give you an approximate heading to a
VOR a long way away and say "fly 200 degrees, then direct ETX when
able".


Because you are required to fly direct, not find your way there by some
indirect route. If you are cleared from present position direct FOOBAR,
you are required to fly along the direct course between those two points.

§ 91.181 Course to be flown.
Unless otherwise authorized by ATC, no person may operate an aircraft
within controlled airspace under IFR except as follows:

(a) On a Federal airway, along the centerline of that airway.


So why are the airways eight miles wide?


I don't know. Why are they? I would like to know.

But it is irrelevant to the issue at hand. The rule says what it says.
