petition for rulemaking1 requesting that the Commission consider rule changes to permit public safety
aircraft voice operations on 700 MHz narrowband channels designated for secondary trunking use in
Section 90.531(b)(7).2 Furthermore, NPSTC recommends that the Commission limit public safety
aircraft voice operations on these channels to two watts effective radiated power, which is consistent
with Section 90.541(d).3
NPSTC bases its proposal on the State of Maryland’s request to deploy air-to-ground voice
operations on 700 MHz narrowband channels so it may incorporate public safety aircraft into its existing
and planned 700MHz networks.4 NPSTC contends that allowing air to ground voice operations at 700
MHz is “a nationwide issue affecting all licensees operating aircraft radios.”5 NPSTC has identified
these secondary trunking channels as the “most appropriate” for public safety aircraft voice operations
because NPSTC believes these channels “are likely to be lightly used and… sharing arrangements among
geographically adjacent agencies can be developed through the Statewide Interoperability Executive
Committees…or similar body in the affected states to minimize interference.”6 Consistent with trunking

We seek comment on whether to initiate a rulemaking proceeding to consider NPSTC’s
recommended rule changes. Commenting parties should address the potential costs and benefits of
NPSTC’s proposal, including: (1) how and in what ways the secondary trunking channels are used today;
(2) the compatibility of the proposed airborne operation with terrestrial use; and (3) what coordination
procedures geographically adjacent licensees should employ to limit interference from airborne operation.
