I have not seen anyone directly answer the question raised by the
poster. What exactly is 'on-course'? Which airway are you supposed to
intercept? MSA may not be operational in nature, but it does tell us
there are 3200' ft obstacles within 25NM. If you proceed at 2300', how
can you remain clear of these obstacles?

You may be remembering some Canadian regs. The MSA is irrelevant. It
has no operational significance and is not part of an instrument
approach procedure. Under Part 91, you don't have any takeoff
minimums.

If you are really concerned, climb over the departure airport until
you feel comfortable in proceeding.

On the way to Pinckneyville last weekend, I stopped at Jimmy Stewart
Field, Indiana, PA. KIDI. I had to shoot the GPS 28 approach with
a cirle to land 10. There's a nice transition off the Revloc VOR.

Since we had a late start, we had planned to stop there for the
night, but by the time we left for the hotel, the overcast had broken
up and it was clear. Next morning, we left VFR.

Looking at the plates, 10/28 has minima 300-1 and 600-1 respectively.
The procedure for runwya 10 is to climb runway heading to 2300 before
proceeding on course. The MSA for the area is 4200. How do you get
from the DP to the nearest Victor airway safely when it's 300 and 1?
