I agree that final approach segments often demand higher precision
than what "the rules" require. My favorite is the ILS 5 to Lawrence,
MA, which ought to be called the cannonball run:

Hm, that's one of my favorite approaches to practice in LIFR. Flying it
to
PTS standards looks safe to me. Is there a hazard I'm failing to
appreciate?


No, not if flown properly. But, with the obstacles where they are, the
margin for error (particularly right around GRAPS where the
smokestacks are) is definitely reduced.

True, but the obstacles are still well beyond both the horizontal and
vertical boundaries of the glideslope.

I probably would not wait for
a full-scale right deflection before missing this approach if the
crosswinds were messing with my head.

Yup, PTS standards call for no more than 3/4 deflection. I'd always go
missed in IMC if I were off by that much.

It might be interesting sometime on a VFR day to fly this with the
localizer on its last dot (just barely not pegged) and also on the
last dot of the glideslope, just to see how much room that really
leaves you. Maybe I'll try it in Flight Simulator tonight just for
kicks.

Cool, I'll give that a try too.
