What you are doing is not pilotage.
Fly a straight line based on compass and wind correction computations.
Time between visual points, towns, bridges, etc to compute ground speed.
Correct the heading slightly based on "observations" from pilotage.

Hmmm? I think what you are describing above is dead reckoning, not
pilotage.




Dead reckoning means no corections based on landmarks wahtsoever.

Pilotage. I try to practice different forms of navigation, and pilotage is a
useful type of navigation for VFR flights.

Yeah, roads and rivers and coastlines are the joy of flying low and
slow.

And the answer to the question is:

No, you fly at 2900 feet.

Why would you follow a river, rivers end.
Why not fly the plane?

An aircraft without DME, LORAN, and GPS may wish to stay out of the Boston
Class Bravo airspace. An excellent way to do that is follow 495 around Boston.
For those that want the torture, I know it can be done with just one VOR.

I see that the 495 is almost north-south (magnetic) in some portions. How do
you manage your altitude when flying that portion of the highway?

A more difficult situation arises when the highway meanders substantially back
and forth from east to west, constantly crossing 360 or 180 degrees. If it's
in hilly country (as it might well be if it has to meander back and forth),
just setting a single heading might not be an option, as you can easily lose
sight of the highway. So, in that case, how does one manage altitude?

You're an idiot

If you are following a road or river or other feature on the ground
while flying VFR, and that feature runs north/south but often veers
off to one side or the other, are you expected to change your altitude
each time you move from a heading of 0-179 to 180-359 or vice versa?

That's for when you're flying with an IFR (I Follow Roads) clearance.
