GM1 CAT.GEN.MPA.210 Location of an aircraft in distress — Aeroplanes ED Decision 2021/008/R OBJECTIVES AND IMPLEMENTATION (a) The purpose of point CAT.GEN.MPA.210 is to have a high probability of timely and accurately locating the accident site after an accident during which the aircraft is severely damaged, irrespective of the accident location and survivability (hence, the terms ‘automatic’, ‘robust’, and ‘accurately’ are used in [CAT.GEN.MPA.210](#_DxCrossRefBm318086055)). The scope of point [CAT.GEN.MPA.210](#_DxCrossRefBm318086055) includes non-survivable accidents. Means compliant with point [CAT.GEN.MPA.210](#_DxCrossRefBm318086055) are expected to: (1) quickly inform the SAR authority concerned that an accident occurred or is about to occur and provide them with information that can easily be used for locating the accident site; and (2) help the safety investigation authority concerned to locate the accident site and the aircraft wreckage so that they can collect evidence in a reasonable time frame. Therefore, if an aircraft in the scope of [CAT.IDE.A.280](#_DxCrossRefBm318086059) complies with CAT.GEN.MPA.210, this aircraft is not required to be equipped with an automatic emergency locator transmitter (ELT). Similarly, if an aircraft in the scope of [CAT.IDE.A.285](#_DxCrossRefBm318086058) complies with CAT.GEN.MPA.210, this aircraft is not required to be equipped with a 8.8-kHz underwater locating device (ULD). (b) The airborne system used to comply with point [CAT.GEN.MPA.210](#_DxCrossRefBm318086055) could rely, for example, on an emergency locator transmitter of a distress tracking type (ELT(DT)), on an automatic deployable flight recorder (ADFR), or on the transmission of position reports at short time intervals (high-rate tracking (HRT)). (c) Subpart A of the Certification Specifications for Airborne Communications, Navigation and Surveillance (CS-ACNS) contains general conditions applicable to the airborne system. Subpart E of CS-ACNS contains specific conditions for meeting the purpose of point [CAT.GEN.MPA.210](#_DxCrossRefBm318086055). (d) If other transmitting equipment than an ELT is used by the airborne system for complying with [CAT.GEN.MPA.210](#_DxCrossRefBm318086055), AMC1 CNS.OR.100 to Part-CNS of the ATM/ANS Regulation contains conditions applicable to the provider of the transmission service that is used by that equipment. (e) While AMC1 CNS.OR.100 only addresses the transmission of information to the SAR authorities, the capability to also transmit that information to the operator is advisable.

Similarly, if an aircraft in the scope of [CAT.IDE.A.285](#_DxCrossRefBm927678438) complies with CAT.GEN.MPA.210, this aircraft is not required to be equipped with a 8.8-kHz underwater locating device (ULD).
