Enlarged sectionals?

The following website has sectionals online that you can enlarge and print
but I believe you have to be a member (of which I am) so I don't know
if it will work for you.

Membership has its hassles.

If it's for a route, plug in the address and airport here
http://aviationtoolbox.org/old/nearby_airports
and then select a "[sectional route]".

Someone uploaded a bunch of high resolution scanned sectionals to
Flightsim.com a few weeks ago. The site requires a membership to download
files, but it's completely free and you could cancel it after you get what
you need. The same files might have been uploaded to avsim.com as well.
They're huge files, of course.

Is that not a great circle, or am I fooled by the projection of the map?

The tool that draws the route just uses the same technique any student
would; it draws a straight line. Sectional maps use the Lambert
Conformal Conic projection so a straight line should be close to
describing a great circle route.

Does that property of the LCC hold across large areas, like the whole
US? I happened to be plotting a course from Oregon to Georgia (in-laws
are moving to Atlanta) and it looked straight and too southerly to me
offhand.

Good question. I don't know the boundary conditions but certainly the
LCC does *not* work across "large" expanses. I think it can suffice
for the conUS, but the rotation required to stitch together the
sectionals might make it unusable in that way.

I suspect that I need to account for the rotations. I'll look into it
more.

Thank you.
