AC 120-55C Air Carrier TCAS - Code7700

AC 120-55C 2/23/11g. Line Checks and Route Checks. When using TCAS-equipped aircraft during line orroute checks, check airmen should routinely incorporate proper TCAS use as a discussion item.h. LOFT. LOFT programs using simulators equipped with TCAS should be enhanced byinteraction with the TCAS. In addition, LOFT programs should consider proper crew vigilancefor aircraft which may not be transponder or Mode C equipped.i. Crew Resource Management (CRM). CRM programs should address effectiveteamwork in responding to TCAS events with emphasis on the following areas:(1) The crew should conduct preflight briefings on how to handle TCAS advisories; and(2) The proper reaction to a TA by the Pilot Flying (PF) and the pilot monitoring (PM).10. OTHER OPERATIONAL ISSUES.a. Manuals and Other Publications. Airplane flight manuals, operating manuals,maintenance manuals, general policy manuals, other manuals, publications, or written material(such as operating bulletins that may relate to TCAS use) must be appropriately amended todescribe TCAS equipment, procedures, and operational policies according to the appropriateregulation.b. MMEL/MEL.(1) Operators formulate necessary TCAS revisions to their MELs for each particular fleet(for example, B727, DC10). MEL revisions must be consistent with the FAA MMEL establishedfor each aircraft type. A summary of the process for addressing the necessary changes to MELitems as well as examples of MMEL and acceptable MEL provisions for TCAS are inAppendix 3.(2) The MMEL changed April 6, 2000, and the relief category changed from C to B forthe entire system.c. Aircraft with TCAS Differences. Operators who have aircraft with TCAS differences indisplays, controls, procedures, or involved with interchange operations must account for thoseTCAS differences. Accomplish this as part of an approved differences training program inaccordance with § 121.418, or as otherwise specified in applicable FAA FSB reports concerningcrew qualification pertaining to a particular airplane type.d. Issues Unique to a Particular Operator. Operators should address any TCAS issuesthat may be unique to their particular route environment, aircraft, procedures, or TCAS displayand control features. Examples include the following:(1) Route Environment Issue. Air carriers having takeoffs or landings outside of thereference TCAS performance envelope (for example, airport elevations outside of the rangebetween sea level and 5,300 feet mean sea level (MSL), or temperatures outside the range ofInternational Standard Atmosphere (ISA) (±50° F) should advise crews of appropriateprocedures and precautions regarding RA compliance.
