    • Course Title: TCAS 2000/ATDL Mode S Transponder System

      The TCAS System is configured for installations in all aircraft types including Commercial Air Transport, Regional, and General Aviation aircraft types. This training course teaches students system description, flight operations, maintenance procedures, interface and general aircraft maintenance procedures. The major components discussed in this course include the TCAS 2000 computer, ATDL Mode S transponder, control panels, VSI/TRA display and directional antenna. This course also includes interface protocol, signal tracing and specifications, and ramp testing for both the TCAS computer and Mode S transponder. A thorough description of LRU end item test requirements, aircraft ground test procedures, and typical flight test procedures is also included.

    • Course Title: T2CAS (TAWS) System

      ACSS integrated TAWS functionality into the TCAS 2000 LRU, allowing operators to combine TAWS and TCAS in a single LRU. The TCAS 2000 is unchanged from the existing ARINC-735A characteristic in terms of operational characteristics and I/O interfaces with the addition of the TAWS capability. This training course will present the TAWS system (including the optional windshear and GPS) and teach the students system description, flight modes of operation, maintenance procedures, interface and general aircraft maintenance procedures. Aircraft interfacing and the Aircraft Personality Module (APM) are discussed in detail with examples of aircraft configurations. Self-testing and data loading are presented in the line maintenance discussion.

      Students should have a good understanding of aircraft systems and basic understanding of analog, digital and ARINC protocols.

    • Course Title: SafeRoute – ADS-B In

      SafeRoute is the suite of Automatic Dependant Surveillance – Broadcast (ADS-B) IN applications that ACSS has certified for operation. The course will cover familiarization with the main SafeRoute applications – SAMM, M&S and CAVS. SAMM, or Surface Area Movement Management, is an ADS-B In application that provides the flight crew with an airport moving map, own-ship location on the map and the location of traffic on the airport surface. The Merging and Spacing, or M&S, application is a Flight Deck based interval management function intended to help streamline airline arrivals. The CDTI Assisted Visual Separation, or CAVS, application is an interval management application intended to aid flight crews in maintaining appropriate separation during final approach. Each of these applications will be discussed in detail, along with a brief discussion of ADS-B and how it differs from standard Mode S broadcasts. Finally, an overview of maintenance procedures unique to the ADS-B In system will be discussed.

      Students should have a good understanding of RF related products, Mode S Transponder Theory and Operations, Air Traffic Control procedures, and basic understanding of analog, digital and ARINC protocols.
