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 system. The TCAS processor and antennas detect and track other aircraft by interrogating their transponders. Aircraft detected, tracked, and displayed by TCAS are referred to as Intruders. TCAS analyzes the transponder replies to determine range, bearing and relative altitude, if the Intruder is reporting altitude. Should the TCAS processor determine that a possible collision hazard exists, it issues visual and aural advisories to the crew. The visual advisory is shown by symbols on the traffic display. Complementing the traffic display, TCAS provides appropriate synthesized voice announcements in the cockpit. A complete list of traffic symbols and announcements is given in the Theory of Operation and Symbology section of this Pilot’s Guide.

TCAS is unable to detect any Intruding aircraft without an operating transponder. TCAS can detect and track aircraft with either an ATCRBS (operating in Mode A or C) or Mode S transponders.

The traffic display shows the Intruding aircraft’s position. TCAS identifies the relative threat of each Intruder by using various symbols and colors. The Intruder’s altitude, relative to your own aircraft’s altitude, is annunciated if the Intruder is reporting altitude. A trend arrow is used to indicate if the Intruder is climbing or descending more than 500 feet per minute. TCAS traffic may be displayed on a weather radar indicator, on a dedicated TCAS display, on a TCAS compatible EFIS Display Unit or a TA/VSI (combination traffic display and vertical speed instrument).

TCAS modes and functions are controlled by switches located on a TCAS control panel or in combination with various other controls. A description of controls is given in the Controls and Displays section of this Pilot’s Guide.

ATC procedures and the “see and avoid concept” will continue to be the primary means of ensuring aircraft separation. However, if communication is lost with ATC, TCAS adds a significant backup for collision avoidance.

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. Relative bearing to the Intruder.

3. Altitude and vertical speed of the Intruder, if the Intruder is

reporting altitude.

4. Closing rate between the Intruder and your aircraft.

Using this data TCAS predicts the time to, and the separation at, the Intruder’s Closest Point of Approach (CPA). Should TCAS predict that certain safe boundaries may be violated, it will issue a Traffic Advisory (TA) to alert the crew that closing traffic is nearby.

TCAS I SENSITIVITY LEVEL

TCAS I separates the surrounding airspace into two altitude layers. A different sensitivity threshold level for issuing TAs (traffic advisories) is applied to each altitude layer. Lower altitudes have less sensitive TA threshold levels to prevent unnecessary advisories in the higher traffic densities anticipated at lower flight levels, i.e., terminal areas.

TCAS I has two sensitivity levels (SL) which are described in Table 1, TCAS Sensitivity Levels. SL A is invoked using the following order of precedence: (1) when the TCAS aircraft is below 2,000 feet AGL (if equipped with radio altimeter) OR (2) when the landing gear is Extended (no radio altimeter installed). SL B occurs under all other flight conditions. Table 2, Typical Traffic Advisory Conditions for Sensitivity Levels describes what conditions will cause a TA to be issued. If aircraft is not equipped with either a radio altimeter or retractable landing gear, TCAS I will stay in SL B at all times.

Sensitivity Level

SL A In sensitivity level A, TCAS I performs surveillance and tracking

functions and provides traffic advisories. The conditions for sensitivity level A are any one of the following:

(1) Own aircraft is in-flight and is below 2,000 feet AGL, if a

radio altimeter is installed.

(2) Own aircraft is in-flight and the Landing Gear is extended, if a

radio altimeter is NOT installed.

Effective Date 6/94 006-08746-0000 Rev 2

DESCRIPTION

Theory of Operation and SymbologyCAS 66A Pilot's Guide

SL B In sensitivity level B, TCAS I performs surveillance and tracking

functions and provides traffic advisories. The conditions for sensitivity 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).

(2) If radio altitude source is NOT installed and own aircraft has

Landing Gear Retracted.

(3) If the aircraft has a fixed landing gear and no radio altimeter is

installed.

Theory of Operation and Symbology

TCAS I SURVEILLANCE VOLUMES

Surveillance volume is that volume of airspace within which other aircraft with Mode S or ATCRBS transponders are tracked by own aircraft’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 processor’s transmitter. The typical range tracking volume is pictured as an ellipse. The distance behind own-aircraft is about one half of the forward distance. The tracking range to either side of own-aircraft is about two thirds of the maximum forward distance.

The maximum forward range for TCAS is 40 nm. TCAS reduces range tracking volumes in high density areas to reduce the number of receptions to be processed by TCAS and for interference limiting. TCAS can track as many as 45 aircraft and displays up to 30 of them.

(2) Altitude Tracking Volumes

TCAS I tracks other transponder equipped aircraft that are within a relative altitude of +/-9,000 feet.

TCAS I AURAL INHIBITS

TCAS I will inhibit the aural annunciation using the following order of precedence: (1) below 400 feet AGL (if equipped with radio altimeter) OR (2) when the landing gear is Extended (no radio altimeter installed). For installations aboard aircraft with fixed landing gear, the aural annunciation is never inhibited by the TCAS I processor. The aural annunciation is enabled above 600 feet AGL in aircraft equipped with a radio altimeter.

Effective Date 5/93 006-08746-0000 Rev 0

Theory of Operation and SymbologyCAS 66A Pilot's Guide

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 location and closing rate. Relative bearing and distance to the Intruder are shown by the position of the Intruder symbol in relation to the own-aircraft symbol.

The symbols change shape and color as separation decreases between your aircraft and Intruders to represent increasing levels of urgency.

The traffic symbols may also have an associated altitude tag that shows relative altitude in hundreds of feet, indicating whether the Intruder is climbing, flying level or descending. A + sign and number above the symbol means the Intruder is above your altitude. A - sign and number beneath indicates the Intruder is below your altitude. A trend arrow appears when the Intruder’s vertical rate is 500 feet per minute or greater.

No altitude number or trend arrow will appear beside any Intruder that is Non-Altitude Reporting (NAR).

If TCAS direction finding techniques fail to locate the azimuth of another aircraft, a NO BEARING message appears on the screen when the Intruder becomes a threat.

NON-THREAT TRAFFIC

An open white diamond indicates that an Intruder’s relative altitude is greater than ±1200 feet, or its distance is beyond 5 nm range. It is not yet considered a threat.

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 evasive maneuvers using information from the traffic display only or on a traffic advisory (TA) only, without visually sighting the traffic. These displays and advisories are intended only for assistance in visually locating the traffic and lack the resolution necessary for use in evasive maneuvering. The flight crew should attempt to visually acquire the intruder aircraft and maintain/attain a safe separation in accordance with the regulatory requirements and good operating practice. If the flight crew can not acquire the aircraft, air traffic control should be contacted to obtain any information that may assist concerning the intruder aircraft. Based on the above procedures minor adjustment to the vertical flight path consistent with air traffic requirements are not considered evasive maneuvers.

BEFORE TAKEOFF

TCAS should be tested using the pilot initiated self test feature during cockpit preparation. After passing self test, TCAS should remain in SBY before takeoff.

TCAS Traffic on the Radar Display:

If the weather radar indicator is used as the TCAS Traffic Display, select Radar to “STBY”, “TST” or “ON”. Note that the weather radar RT is radiating when in the radar is On. See the weather radar operator’s guide for proper radar operation. Select the “T/WX” (TCAS/Weather) Display Mode switch to display TCAS, i. e., “TA AUTO” or “TA ONLY”.

Before taking the active runway, TCAS should be turned ON. Range, if available, may be selected to 10 nm or lower. Above/Norm/Below, if available, may be selected to ABOVE.

FLIGHT PROCEDURES

The TCAS TA (traffic advisory) should alert the flight crew to use extra vigilance to identify the Intruding aircraft. Any time the traffic symbol becomes a yellow circle or “TRAFFIC, TRAFFIC” is announced in the cockpit, conduct a visual search for the Intruder. If successful, maintain visual acquisition to ensure safe separation.

Effective Date 5/99 006-08746-0000 Rev 5

Operational ProceduresCAS 66A Pilot's Guide

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. If a TA occurs, select the 10 nm range or lower on the TCAS traffic display.

During cruise, the longer TCAS ranges may be used. The Above/Norm/Below selection should be NORM. A 10 NM (or greater) range may be selected for high altitude cruise.

During Descent and Approach, Below may be selected using the Above/Norm/Below switch. A TCAS range of 10 nm or lower may be used.

1. If a stall warning occurs during a TA, immediately execute the stall recovery procedure. TCAS will continue to provide TA alerts during a stall warning.

2. If a TA occurs while in the landing configuration, conduct a visual search for the Intruder. A TA does not mandate a missed approach.

3. If a TA is encountered during a high speed buffet, adjust pitch force as necessary to reduce buffet.

4. While it is extremely rare, GPWS or Wind Shear may issue an alert while a TA (traffic advisory) is in progress. If this occurs, TCAS will automatically inhibit the TCAS audio alerts, but visual display of TAs will continue.

AFTER LANDING

After departing the active runway, TCAS should be turned to Standby (SBY) or Off.

Post Flight

If a failure of the TCAS system has occurred, give Maintenance as much specific information about the problem as possible. Avoid phrases such as “TCAS Inop.” Provide information in terms of fault lights lit, audio announcements, test pattern discrepancies and screen annunciations that indicate which unit was observed to have failed.

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.

If the Intruder is Non-Altitude Reporting (NAR), TCAS will display only the range and bearing. It can issue a TA (Traffic Advisory) based on distance and direction of flight. TCAS assumes NonAltitude Reporting (NAR) traffic is at the same altitude as your own aircraft.

Intruders considered on the ground by the system will not be displayed.

Wiring options for TCAS also include the following:

* TCAS can be wired to display all traffic full time or all traffic only

as a result of the presence of a TA.

* The maximum number of targets displayed (3 - 30) can be

selected by strapping.

* The TCAS display may have pilot selectable range or may be a

fixed range controlled by the aircraft wiring.

* The TCAS system can be automatically placed in standby when

the aircraft is on the ground.

* The manually initiated system self test can be inhibited in flight.

* An aircraft lamp test switch can be wired to control the TID

66A/D & IVA 81A/C/D sequential lamp test.

* TCAS can be wired to give GPWS and Wind Shear a higher

aural warning priority.

If a radio altimeter is installed, the TCAS I aural warning (TRAFFIC, TRAFFIC) is inhibited below 400 feet AGL during descent and below 600 feet during ascent. If no radio altimeter is installed, then the aural warning is inhibited whenever the Landing Gear is EXTENDED.

System ConsiderationsCAS 66A Pilot's Guide

NOTES (CON'T)

It is possible to see an aircraft flying the same course and direction 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). If there is no closure rate, no advisory will be issued, unless the Intruder is very close (within approximately 0.2 mile). Conversely, traffic at the same altitude very far ahead (about 10 miles) may be shown as a TA by TCAS because of a very rapid closure rate.

Appendix

TCAS SELF TEST

The TCAS self test determines the operational status of the entire TCAS system. Select self test on the TCAS control panel. Once begun, self test continues automatically for approximately eight seconds. During self test, normal TCAS operation is inhibited. For optimum display during self test, selection of the 5 nm range is recommended.

If the traffic display is a weather radar indicator and the indicator is OFF, turn On the indicator before selecting TCAS self test. The warm up time for weather radar indicators is about five seconds.

During the first few seconds of the test sequence, the traffic display allows verification of each type of Intruder symbol. The test generates the symbols arranged as shown. The traffic display annunciates the word TEST. If the weather radar is in the TEST function, this pattern appears over the radar test pattern. If in a weather function, this test appears over the weather.

Use of the TCAS self test function in flight will inhibit normal TCAS operation for up to 15 seconds. For this reason, the pilot should use caution when initiating the test in flight.

IVA 81A/C/D & TID 66A/D TCAS I Test Patterns; 5NM range

A Traffic Advisory (yellow circle) will appear at 9 o’clock, range of 2 miles, 200 feet below and climbing.

Proximity traffic (solid white diamond) will appear at 1 o’clock, range

3.6 miles, 1000 feet below, descending.

Non-Threat traffic (open white diamond) will appear at 11 o’clock, range of 3.6 miles, flying level 1000 feet above.

Effective Date 2/06 006-08746-0000 Rev 7

AppendixCAS 66A Pilot's Guide

At the conclusion of a successful Self Test, a synthesized voice announces:

“TCAS SYSTEM TEST OK”

FAILURE CONDITIONS:

Should a failure be detected during self test, the audio message says:

“TCAS SYSTEM TEST FAIL”

A “TCAS” flag will be annunciated on the traffic display. A self test failure may indicate that the auxiliary equipment required for TCAS is not operational. Check the associated equipment.

If the traffic display is a radar indicator, the appropriate failure message will be displayed. See WX & TCAS Message Format in Section II: Controls and Displays.

Should a VSI failure be detected at any time, the VSI flag will appear on the TA/VSI (IVA 81A/C/D). A “VSI” flag is not caused by the TCAS processor.

CP 66A/B CONTROL PANEL TEST

Pressing the TST button on the CP 66A/B initiates a comprehensive TCAS self test lasting approximately eight seconds. The system will return to the previously selected modes when the test is complete.

IVA 81A/C/D & TID 66A/D OPTIONAL LAMP TEST

The optional lamp test produces an array of traffic in the pattern shown. The climb/descend color bands alternate between green and red, lasting for two seconds each. The bands are blank for a one second interval in between.

Note: The VSI function of the TA/VSI ( IVA 81A/C/D) will not be observed during the lamp test.

RADIO ALTIMETER

If RALT is installed and is inoperative, TCAS will be Inoperative.

GLOSSARY OF TCAS TERMS

ABBREVIATIONS AND DEFINITIONS

AFM or AFMS Airplane Flight Manual or Airplane Flight Manual Supplement.

AGL Above Ground Level. Height above the ground.

ATC Air Traffic Control. A federally operated ground based system

that manages aircraft traffic flow.

ATCRBS ATC Radar Beacon System. A ground based secondary radar and airborne transponder system used to monitor traffic.

Absolute Altitude The altitude shown on a traffic display is described as Absolute whenever the FL mode has been selected. Otherwise, TCAS displays the Relative Altitude between your own aircraft’s pressure altitude and the encoded altitude of the Intruder aircraft.

Altitude Tag Data tag shown above or below threat symbol giving the relative altitude of the Intruder.

BITE Built-In Test Equipment. A feature of TCAS that continuously monitors itself for operational errors.

CPA Closest Point of Approach. CPA refers to predicted point at which the Intruder will be closest to your own aircraft.

FLFlight Level. This is a TCAS mode that allows the annunciation of Absolute Altitude on the traffic display. The traffic display will indicate the altitude in hundreds of feet, I. E., 190 is 19,000 feet.

Indicated Altitude Altitude shown on the altimeter with barometric correction setting set to local sea level pressure. Indicated altitude is used by the crew below 18,000 feet but not used for TCAS processing.

Intruder Any aircraft that is in the surveillance range of TCAS.

LRU Line Replaceable Unit. A self-contained avionics component

that can be replaced in the field.

Mode A Transponder ATCRBS transponder that replies to ATC interrogations sending identification code but without giving altitude data.

Mode C Transponder ATCRBS transponder that replies to ATC interrogations giving identification code or encoded altitude data.

Effective Date 6/94 006-08746-0000 Rev 2

AppendixCAS 66A Pilot's Guide

Mode S Transponder Transponder that replies to ATC interrogations giving an ATCRBS identification code, encoded altitude and other data fields including discrete aircraft address and airspeed capability.

NAR Non-Altitude Reporting traffic.

Non-Threat Intruder An aircraft that has entered the TCAS surveil-

lance volume at a distance greater than 5 miles or altitude greater than 1200 feet above or below your own aircraft.

Pressure Altitude Indicated altitude when barometric pressure is set to 29.92” Hg. (1013mb). Pressure altitude is used by TCAS to determine the relative altitude of traffic.

Proximity Intruder An aircraft that is within 5 miles range and within 1200 feet above or below your own aircraft but does not meet the TCAS definition of a threat.

Rad Alt or RALT Radio Altitude is the height above the ground as determined by a radio altimeter. RALT isused by TCAS to inhibit TAs close to the surface. Radio altitude above terrain is absolute. As such, RALT height is sometimes referred to as absolute altitude in some systems. RALT systems typically function below 2,500 ft AGL.

Relative Altitude The difference in altitude between two aircraft. TCAS calculates relative altitude as the difference between your own aircraft’s pressure altitude and the encoded pressure altitude of the Intruder.

Self Test A functional test that determines equipment status. Self test differs from BITE performance monitoring because it is initiated by the crew and is not performed continually or automatically.

Sensitivity Level TCAS I has two sensitivity levels (SL). SL A shall be automatically invoked using the following order of precedence: (1) when the TCAS aircraft is below 2,000 feet AGL (if equipped with radio altimeter) OR (2) when the landing gear is Extended (no radio altimeter installed). SL B occurs under all other flight conditions. If aircraft is not equipped with either a radio altimeter or retractable landing gear, TCAS I shall stay in SL B at all times.

Surveillance Volume The volume of airspace surrounding your aircraft that TCAS scans for Intruding traffic. The TCAS system scans approximately 40 NM in front of and 9000 feet above and below the aircraft. The volume will automatically begin to decrease when flying into a high density area and may be reduced to approximately 15 NM in front of the aircraft.

Effective Date 6/94006-08746-0000 Rev 2

Appendix

TA Traffic Advisory. An audio and visual indication that another aircraft is a potential threat.

TA/VSI Traffic Advisory/Vertical Speed Indicator. A flight instrument that gives standard VSI indication and plan position of TCAS traffic.

Threat An aircraft that has satisfied TCAS threat detection logic and thus requiring a Traffic Advisory.
