            Subpart B_Nondirectional Radio Beacon Facilities

 

Sec. 171.29  Installation requirements.



    (a) The facility must be installed according to accepted good 

engineering practices, applicable electric and safety codes, and FCC 

licensing requirements.

    (b) The facility must have a reliable source of suitable primary 

power.

    (c) Dual transmitting equipment may be required to support some IFR 

procedures.

    (d) A facility intended for use as an instrument approach aid for an 

airport must have or be supplemented by (depending on the circumstances) 

the following ground-air or landline communications services:

    (1) At facilities outside of and not immediately adjacent to 

controlled airspace, there must be ground-air communications from the 

airport served by the facility. Voice on the aid controlled from the 

airport is acceptable.

    (2) At facilities within or immediately adjacent to controlled 

airspace, there must be the ground-air communications required by 

paragraph (d)(1) of this section and reliable communications (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 section 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 factor, the requirements of paragraphs (d) (1) and (2) of this 

section may be reduced 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 communicate 

with aircraft during the proposed instrument approach procedure, at 

least down to the minimum en route altitude for the controlled airspace 

area.
