47 CFR 87.475 - Frequencies.

Status message

There is 1 rule appearing in the Federal Register for 47 CFR 87. View below or at eCFR (GPOAccess)
§ 87.475 Frequencies.
(a) Frequency coordination. The Commission will assign frequencies to radionavigation land stations and radionavigation land test stations after coordination with the FAA. The applicant must notify the appropriate Regional Office of the FAA prior to submission to the Commission of an application for a new station or for modification of an existing station to change frequency, power, location or emission. Each application must include the FAA Regional Office notified and date of notification.
(b) Frequencies available for radionavigation land stations.
(1) LORAN-C is a long range navigation system which operates in the 90-110 kHz band.
(2) Radiobeacon stations enable an aircraft station to determine bearing or direction in relation to the radiobeacon station. Radiobeacons operate in the bands 190-285 kHz; 325-435 kHz; 510-525 kHz; and 525-535 kHz. Radiobeacons may be authorized, primarily for off-shore use, in the band 525-535 kHz on a non-interference basis to travelers information stations.
(3) Aeronautical marker beacon stations radiate a vertical distinctive pattern on 75 MHz which provides position information to aircraft.
(4) The following table lists the specific frequencies in the 108.100-111.950 MHz band which are assignable to localizer stations with simultaneous radiotelephone channels and their associated glide path station frequency from the 328.600-335.400 MHz band.

(5) VHF omni-range (VOR) stations are to be assigned frequencies in the 112.050-117.950 MHz band (50 kHz channel spacing) and the following frequencies in the 108-112 MHz band:
108.200 108.250 108.400 108.450 108.600 108.650 108.800 108.850 109.000 109.050 109.200 109.250 109.400 109.450 109.600 109.650 109.800 109.850 110.000 110.050 110.200 110.250 110.400 110.450 110.600 110.650 110.800 110.850 111.000 111.050 111.200 111.250 111.400 111.450 111.600 111.650 111.800 111.850 112.000
(6) The band 960-1215 MHz is available for the use of land stations and associated airborne electronic aids to air navigation. When distance measuring equipment (DME) is intended to operate with a single VHF navigation station in the 108-117.975 MHz band, the DME operating channel must be paired with the VHF channel as shown in the following table:

(1) The frequencies set forth in §§ 87.187(c), (e) through (j), (r), (t), and (ff) and 87.475(b)(6) through (b)(10), and (b)(12) may be assigned to radionavigation land test stations for the testing of aircraft transmitting equipment that normally operate on these frequencies and for the testing of land-based receiving equipment that operate with airborne radionavigation equipment.
(2) The frequencies available for assignment to radionavigation land test stations for the testing of airborne receiving equipment are 108.000 and 108.050 MHz for VHF omni-range; 108.100 and 108.150 MHz for localizer; 334.550 and 334.700 MHz for glide slope; 978 and 979 MHz (X channel)/1104 MHz (Y channel) for DME; 978 MHz for Universal Access Transceiver; 1030 MHz for air traffic control radar beacon transponders; and 5031.0 MHz for microwave landing systems. Additionally, the frequencies in paragraph (b) of this section may be assigned to radionavigation land test stations after coordination with the FAA. The following conditions apply:
(i) The maximum power authorized on the frequencies 108.150 and 334.550 MHz is 1 milliwatt. The maximum power authorized on all other frequencies is one watt.
(ii) The pulse repetition rate (PRR) of the 1030 MHz ATC radar beacon test set will be 235 pulses per second (pps) ±5pps.
(iii) The assignment of 108.000 MHz is subject to the condition that no interference will be caused to the reception of FM broadcasting stations and stations using the frequency are not protected against interference from FM broadcasting stations.
