It is the responsibility of those installing this article either on or within a specific type or class of aircraft to determine that the aircraft installation conditions are within the TSO standards. TSO articles must have separate approval for installation in an aircraft. The article may be installed only if performed under 14 CFR part 43 or the applicable airworthiness requirements. The GNS 480 WAAS/GPS receiver is compatible on aircraft equipped with SATCOM when installed with an appropriate antenna. See table notes in Section 1.3.10 for more information on compatible antennas. 5.3.1 GPS Antenna The WAAS/GPS receiver is compatible with the GPS antennas listed in Section 1.3.10. Antenna selection may affect operational limitations. 5.3.2 Antenna Installation – General GNS 480 interfaces to GPS antennas other than those identified in this installation manual are outside the scope of this manual and may require further evaluation for certification and/or other FAA airworthiness approval. 5.3.3 Equipment Interfaced to the GNS 480 GNS 480 interfaces to aircraft systems other than those shown in this installation manual are outside the scope of this manual and may require further evaluation and/or certification approval. All equipment interfaced to the GNS 480 must be previously or concurrently approved. 5.3.4 Preservation of Previous Systems It is the installer’s responsibility to preserve the essential characteristic of the aircraft being modified by this manual to be in accordance with the aircraft manufacturer’s original design. This includes the preservation of multiple power buses, which reduce the probability of interrupting power to essential instruments and avionics. For Aircraft on the AML certified under 14 CFR Part 23 post amendment 41, use of the GNS 480 for IFR operations requires a functional redundant electrical power system. 5.3.5 Aircraft Radio Station License An aircraft radio station license is not required when operating in U.S. airspace, but may be required when operating internationally.
