Can anyone explain the reason for the note "maximum procedure turn
entry altitude 6000 feet" on the ILS or LOC RWY 20 at KALW, Walla Wala
Regl, WA? Is this a TERPs thing? Other approaches the same?

Here's the link, I think

My guess is that if you enter the PT above 6000, you can't make it down to
the runway without exceeding some TERPS-mandated maximum descent profile.

If you flew the PT as a teardrop entry, 1 minute outbound, roughly 1 minute
to turn around, 1 minute inbound, that's 2700 feet to lose in 3 minutes, or
900 ft/minute. Pretty steep.

Is there anything that says you can't make more than one
lap around the loop?

Are there enroute altitudes in the area that would lead
to being quite high when nearing the approach area?

Is there a reception problem with the navaid(s) defining
the pattern?
