shall include an RCP-130 performance standard as well as SatVoice standards. (4) Training of radio operators on new operation procedures and protocols. (5) A phased implementation plan for incorporating SatVoice services into the AMCS program. (6) The estimated cost of the implementation procedures for relevant stakeholders. (d) HF/VHF minimum equipage The addition of SatVoice capability as an added means of communication in oceanic and remote continental airspace shall in no way affect the current HF/VHF equipage requirement for communications in such airspace. The Administrator shall maintain existing HF/VHF services as minimum equipage under the AMCS program to provide for auxiliary communication and maintain safety in the event of a satellite outage. 409. Low altitude routes for vertical flight (a) Sense of Congress It is the sense of Congress that the national airspace system requires additional rotorcraft, including advanced air mobility aircraft, low-altitude instrument flight rules routes leveraging advances in performance based navigation to operate on direct, safe, and reliable routes that ensure sufficient separation from higher altitude fixed wing aircraft traffic. (b) Low-altitude rotorcraft instrument flight routes (1) In general Not later than 1 year after the date of enactment of this section, the Administrator shall initiate a rulemaking process to— (A) incorporate instrument flight rules rotorcraft operations into the low-altitude performance based navigation procedure infrastructure
