Default ILS critical area when the tower is closed?

As you're the one who brought the .65 (ie, controllers, their duty
requirements, and thus a situation where the tower is open) into the thread
it's only fair you should be the one to de-creep it.


No, I brought in the .65 language after someone else had quoted the
alert language contained in that order.

And when the tower *is* open that aircrew would be equally savvy not to
assume the critical areas are protected simply because ATC forgot to issue
an advisory.


Here is what AIM 1-9-9 k says about it and has said pretty much the same
thing for a long time. Note the phrase "to ensure that the ILS critical
areas are protected..." (during weather better than 800-2):

(2) Glide Slope Critical Area. Vehicles and aircraft are not authorized
in the area when an arriving aircraft is between the ILS final approach
fix and the airport unless the aircraft has reported the airport in
sight and is circling or side stepping to land on a runway other than
the ILS runway.

(b) Weather Conditions. At or above ceiling 800 feet and/or visibility 2
miles.

(1) No critical area protective action is provided under these conditions.

(2) A flight crew, under these conditions, should advise the tower that
it will conduct an AUTOLAND or COUPLED approach to ensure that the ILS
critical areas are protected when the aircraft is inside the ILS MM.

I guess the AIM tells pilots one thing and controllers tell controllers
another thing. That has been going on for a lot longer than 27 years.
