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.
