b) aeronautical station transmitters: for transmitter power up to and including 50 W: [43 + 10 log10Pp (W)] dB For transmitter power more than 50 W: 60 dB. Note.— See Figures 2-1 and 2-2. 2.4.1.8 POWER 2.4.1.8.1 Aeronautical station installations. Except as permitted by the relevant provisions of Appendix S27 to the ITU Radio Regulations, the peak envelope power (Pp) supplied to the antenna transmission line for H2B, H3E, J3E, J7B or J9B classes of emissions shall not exceed a maximum value of 6 kW. 2.4.1.8.2 Aircraft station installations. The peak envelope power supplied to the antenna transmission line for H2B, H3E, J3E, J7B or J9B classes of emission shall not exceed 400 W except as provided for in Appendix S27 of the ITU Radio Regulations as follows: S27/68 It is recognized that the power employed by aircraft transmitters may, in practice, exceed the limits specified in No. 27/60. However, the use of such increased power (which normally should not exceed 600 W Pp) shall not cause harmful interference to stations using frequencies in accordance with the technical principles on which the Allotment Plan is based. S27/60 Unless otherwise specified in Part II of this Appendix, the peak envelope powers supplied to the antenna transmission line shall not exceed the maximum values indicated in the table below; the corresponding peak effective radiated powers being assumed to be equal to two-thirds of these values: Class of emission Stations Max. peak envelope power (Pp) H2B, J3E, J7B, J9B, A3E*, H3E* (100% modulation) Aeronautical stations Aircraft stations 6 kW 400 W Other emission such as A1A, F1B Aeronautical stations Aircraft stations 1.5 kW 100 W * A3E and H3E to be used only on 3 023 kHz and 5 680 kHz. 2.4.1.9 Method of operation. Single channel simplex shall be employed. Part II Annex 10 — Aeronautical Communications II-2-9 22/11/07 FIGURES FOR CHAPTER 2 Figure 2-1.
