Sec. 22.857 Channel plan for commercial aviation air-ground systems.
The 849-851 and 894-896 MHz frequency ranges are allocated for block
assignment to nationwide air-ground systems providing radiotelephone
service to passengers aboard commercial aircraft. These frequency ranges
may also be used to provide service to persons in general aviation or
other aircraft. Ground stations transmit on channels in the 849-851 MHz
range. Airborne mobile stations transmit on
[[Page 181]]
channels in the 894-896 MHz range. Systems using these channels must
conform to the channel plan described in this section.
(a) Channel blocks. The spectrum allocated for commercial aviation
air-ground systems is divided into ten channel blocks, numbered 1
through 10. All ground stations in each geographical area must use the
same channel block for communication with airborne mobile stations in
flight, in accordance with Sec. 22 .859 .
(1) Each channel block is subdivided into 6 control channels labeled
P-1 through P-6, and 29 communications channels labeled C-1 through C-
29.
(2) The authorized channel bandwidths are as follows:
(i) Each control channel has a bandwidth of 3 .2 kHz.
(ii) Each communications channel has a bandwidth of 6 kHz.
(b) The center frequencies (in MegaHertz) of the communications and
control channels are listed in Tables G-1 and G-2 of this section.
