background image No PBN/ code needs to be filed to indicate the ability to fly point - to - point routes using GNSS or INS. Filing one of these four area navigation capabilities as shown does not indicate performance based navigation sufficient for flying Q - Routes, T - Routes, or RNAV SIDs or STARs. To qualify for these routes, see the section on Performance Based Navigation Routes. (c) Transponder Capabilities (Item 10b) For domestic flights, it is not necessary to indicate Mode S capability. It is acceptable to simply file one of the following codes in TBL 4 - TBL 4 - Mode C Capability Item 10b Transponder with no Mode C Transponder with Mode C International flights must file in accordance with relevant AIPs and regional supplements. Include one of the Mode S codes in TBL 4 - 9, if appropriate. NOTE - File only one transponder code.

The accompanying entry in Item 18 indicates that the equipment is compliant with 14 CFR 91.227. Some ADS - B equipment used in other countries is based on an earlier standard and does not meet U.S. requirements. Do not file an ADS - B code for "in" capability only. There is currently no way to indicate that an aircraft has "in" capability but no "out" capability. For aircraft with ADS - B "out" on one frequency and "in" on another, include only the ADS - "out" code. For example, B1 or U1, (See TBL 4 - 10).
