procedure, and it has no place in the procedure. YMMV.

I know what you mean and usually if it is an emergency, looking at the
plate, figuring out where you are and which way you have to go might
be too late.

My friend (and i guess the rest of UA pilots) simply use it to get an
idea of the height of obstacles/terrain for descent planning. If the
MSA is 1000' AGL, you are pretty free
to descend anytime. If it is 6000' AGL, well you know where the
terrain/obstacles are and you should take a closer look at exactly
where they are and probably best to descend much later on in
the approach. I guess the best example is you are getting RV to
a fix. You are off of an established airway and the controller
says "Cleared for the approach...cross XXX at 3000." The MSA gives
you an idea when to get down in a safe manner. Agreed that it is quite
basic without too much use.
