AMC1 ACNS.E.LAD.140 Activation signals — essential information ED Decision 2021/008/R ACCEPTABLE MEANS OF COMPLIANCE APPLICABLE TO ALL SOLUTIONS (a) If the activation signals are transmitted in flight, every activation signal containing information that is used to determine the latitude or longitude of the aircraft should be sent no later than 2 seconds after the time at which this information is valid. (b) The information that is used to determine the latitude and longitude of the aircraft should be included in the activation signals even if this information is inaccurate. (c) If an activation signal contains latitude or longitude information, this information should be provided in the World Geodetic System 84 (WGS84) (G1150 or later) or in another realisation of the International Terrestrial Reference Frame (IERS) (2000 or later). (d) The information contained in the activation signals or their characteristics should be sufficient to determine with certainty whether those signals were transmitted by an automatic ELT, an ELT(DT), or another type of equipment.
