9. Constraints on Development: Regulation  Radio Regulation:  ITU, CEPT, ETSI  Frequency bands  Conditions on use (e.g. spurious, eirp etc)  Level of protection  Aviation Regulation:  ICAO Convention on International Civil Aviation  General Principles  Equipment interoperability  Safety  RTCA/EUROCAE Minimum Operational Performance Standards  SESAR  EASA  CAA

10. Constraints on Development: ICAO Convention on……  Article 3: Civil and State aircraft  This convention shall be applicable only to civil aircraft and shall not be applicable to state aircraft  Aircraft used in military, customs and police services shall be deemed to be state aircraft  The contracting States undertake, when issuing regulations for their state aircraft, that they will have due regard for the safety of navigation of civil aircraft  Article 5: Rights of non-scheduled flight  Each contracting State agrees that all aircraft of the other contracting States, being aircraft not engaged in scheduled international air services shall have the right, subject to the observance of the terms of this Convention, to make flights into or in transit non-stop across its territory……  Article 22: Facilitation of formalities  Each contracting State agrees to adopt all practicable measures, through the issuance of special regulations or otherwise, to facilitate and expedite navigation by aircraft between the territories of contracting States.  Article 30: Aircraft radio equipment  Aircraft of each contracting State may, in or over the territory of other contracting States, carry radio transmitting apparatus only if a license to install and operate such apparatus has been issued by the appropriate authorities of the State in which the aircraft is registered  Article 37: Adoption of international standards and procedures  Each contracting State undertakes to collaborate in securing the highest practicable degree of uniformity in regulations, standards, procedures, and organisation in relation to aircraft…. In all matters in which such uniformity will facilitate and improve air navigation

12. Remotely Piloted Aircraft Spectrum to support command and non-payload communication Access to additional spectrum ( ≈150 MHz) Wireless Avionics Replacement of wires with radio systems Increased diversity of routing Additional sensors Accommodated in existing aeronautical allocations Wingtip Radar Avoid collisions whilst taxiing Use of automotive radar No additional spectrum requirements Space Planes Virgin Galactic Spectrum requirement being investigated (type, quantity, propagation) Future Evolution/Revolution : Known Developments

13. Work holistically across in a multidiscipline environment to:- Identify Required Future Global ATM System (2060 and beyond) Requires Minimum Equipment Fit Rationalising Systems where Possible Workable Transition Plan that is Adhered to Justified Protection Criteria Can be Globally Harmonised and Implemented Benefits Aviation Controls its own Destiny Possible Release of Spectrum Reduced Equipage in the Air and on the Ground Less fuel burn Reduced CO 2 emissions/maintenance/AIP/etc ?

14. Definition of Radio Frequency Management: “Radio frequency management is done by experts who meld years of experience with a curious blend of regulation, electronics, politics and not a little bit of larceny. They justify requirements, horse trade, coerce, bluff and gamble with an intuition that cannot be taught other than by long experience” Vice Admiral Jon L. Boyes U.S. Navy
