§ 171.31
(2) At facilities within or imme-
diately adjacent to controlled airspace,
there must be the ground-air commu-
nications required by paragraph (d)(1)
of this section and reliable communica-
tions (at least a landline telephone)
from the airport to the nearest FAA
air traffic control or communication
facility.
Paragraphs (d) (1) and (2) of this sec-
tion are not mandatory at airports
where an adjacent FAA facility can
communicate with aircraft on the
ground at the airport and during the
entire proposed instrument approach
procedure. In addition, at low traffic
density airports within or immediately
adjacent to controlled airspace, and
where extensive delays are not a fac-
tor, the requirements of paragraphs (d)
(1) and (2) of this section may be re-
duced to reliable communications (at
least a landline telephone) from the
airport to the nearest FAA air traffic
control or communications facility, if
an adjacent FAA facility can commu-
nicate with aircraft during the pro-
posed instrument approach procedure,
at least down to the minimum en route
altitude for the controlled airspace
area.
