  • Page 6: Introduction

    Introduction INTRODUCTION TCAS (an acronym formed from the phrase Traffic Alert and Collision Avoidance System) is an airborne system used for detecting and tracking aircraft near your own aircraft. TCAS I includes a TCAS processor, antennas, a traffic display and a means to control the sys- tem.

  • Page 10: Tcas Operation

    Theory of Operation and Symbology TCAS OPERATION TCAS monitors the airspace surrounding your aircraft by interrogating the transponder of the Intruding aircraft. The interrogation reply enables TCAS to compute the following information about the Intruder: 1. Range between your aircraft and the Intruder. 2.
  • Page 11 CAS 66A Pilot's Guide Theory of Operation and Symbology SL B In sensitivity level B, TCAS I performs surveillance and tracking functions and provides traffic advisories. The conditions for sen- sitivity level B are based on own aircraft in-flight and: (1) If radio altitude source is installed and own aircraft altitude is above 2,000 feet AGL (radio altitude).

    Theory of Operation and Symbology TCAS I SURVEILLANCE VOLUMES Surveillance volume is that volume of airspace within which other air- craft with Mode S or ATCRBS transponders are tracked by own air- craft’s TCAS. (1) Range Tracking Volumes The shape and size of the range tracking volume is dependent on whether Mode S or ATCRBS transponders are being interrogated, whether tracking is occurring on a directional or OMNI antenna, and attenuation levels applied to the transmitted pulses from the TCAS...

  • Page 13: Tcas Traffic Display Symbols

    CAS 66A Pilot's Guide Theory of Operation and Symbology TCAS TRAFFIC DISPLAY SYMBOLS TCAS I will display three different traffic symbols on the traffic display. The type of symbol selected by TCAS is based on the Intruder’s loca- tion and closing rate. Relative bearing and distance to the Intruder are shown by the position of the Intruder symbol in relation to the own-air- craft symbol.

    Operational Procedures TCAS OPERATING PROCEDURES TCAS warns the operator with an aural and visual Traffic Advisory whenever TCAS detects another transponder equipped aircraft and predicts the Intruder to be a threat. The pilot should not initiate eva- sive maneuvers using information from the traffic display only or on a traffic advisory (TA) only, without visually sighting the traffic.

    CAS 66A Pilot's Guide Operational Procedures Use of the TCAS self-test function in-flight will inhibit TCAS operation for up to eight seconds. During initial departure, select the 10 nm TCAS range or lower because the traffic density is the greatest near the airport. During the climb phase of flight, select the 10 nm range or greater and continue to use the Above display volume mode, if available.

  • Page 48: Limitations And Notes

    System Considerations LIMITATIONS AND NOTES LIMITATIONS Refer to the Airplane Flight Manual . NOTES The capability of TCAS is dependent upon the type of transponder in the Intruding aircraft: The Intruding aircraft must be equipped with a properly operating transponder for normal TCAS operation. TCAS is unable to detect any aircraft without an operating transponder.
  • Page 49 CAS 66A Pilot's Guide System Considerations NOTES (CON'T) It is possible to see an aircraft flying the same course and direc- tion as your own aircraft, yet TCAS may not consider it a threat. TCAS calculates the closure rate of the Intruder, and derives the time to the Closest Point of Approach (CPA).

Once begun, self test continues automatically for approximately eight seconds. During self test, normal TCAS operation is inhibited. For optimum display dur- ing self test, selection of the 5 nm range is recommended.
