Default ILS critical area when the tower is closed?

How many fields are there where this is a concern? I would expect most
fields with the congestion to require marked ILS critical areas to have
full-time towers.


I can't provide a cite, but I was told recently that there are ILS
critical areas at part-time towered airports.

HPN has one. Two actually, one at each end.

I did a quick survey (via the airport diagrams available on airnav) of
part-time towers I know around here that have ILS's. None of OCX, FRG,
ISP, MMU, POU, BDR, and HVN appear to have ILS critical areas (at least
none that are charted on the airport diagram), but HPN does.

Interestingly enough, at both ends of the runway at HPN, the ILS Hold Short
lines are only on the taxiways on the left side (as viewed from the
approach) of the runway, which is the side the GS antenna is on in both
cases.
