Appendix D – Differences between CS ACNS.D.ELS and JAA TGL 13 Rev1 ED Decision 2022/008/R To demonstrate compliance with the CS-ACNS elementary surveillance requirements, the following additional points need to be addressed for aircraft previously compliant with Joint Aviation Authorities (JAA) Temporary Guidance Leaflet (TGL) 13 Revision 1: (a) verification that the aircraft identifications sent in ‘extended squitter’ messages and in the Mode S replies are identical (see [CS ACNS.D.ELS.015(b)(2)](#_DxCrossRefBm573002703)); (b) verification that the pressure altitudes provided in ‘extended squitter’ messages and in Mode S replies are identical if the installation sends ‘extended squitter’ messages (see [CS ACNS.D.ELS.015(b)(2)](#_DxCrossRefBm573002703)); and (c) other parameters provided by the airborne surveillance system are verified as correct and are correctly indicated, as available (see [CS ACNS.D.ELS.015(b)(1)](#_DxCrossRefBm573002703)). Note. The tests of the other parameters transmitted by the system allow certification of aircraft not subject to full EHS mandate but capable of transmitting some of the parameters which can be used by the operational systems.
