Q

What is the TCAS basis of operation?

A

TCAS identifies nearby aircraft with operating transponders. Mode 3A are processed for lateral data, Mode 3A & C provide lateral and vertical data. Warnings are based on predicted flight paths.

Q

How many seconds out is a Traffic Advisory?

A

20 - 48 seconds

17
Q

How many seconds out is a Resolution Advisory?

A

20 - 30 seconds

18
Q

How many targets will TCAS track?

A

Up to 45 targets

19
Q

How many targets will TCAS display?

A

Up to 30 targets to display, five on the PFD

20
Q

Will ground targets be displayed?

A

No. In general, if the target is within 400 feet of the ground it will not be displayed

21
Q

Under what conditions will ONLY Traffic Advisories be displayed? hint: there are four

A
  1. Cargo door/ramp open
  2. Paratroop door open
  3. TAWS alerts
  4. LPCR Windshear Alerts
22
Q

Which has higher priority: TAWS or TCAS ?

A

TAWS In case of simultaneous alarm, TCAS is placed in TA ONLY mode

23
Q

Symbol “White Diamond Outline (empty)”

A

Non Threat Aircraft = White Diamond Outline

24
Q

Symbol “White Diamond Filled (solid)”

A

Proximate Aircraft - White Filled Diamond is within 6 nm and 1200 feet

25
Q

Symbol “Yellow Filled Circle”

A

Traffic Advisory (TA) Yellow Filled Circle - Range/Closure rate warrants special attention. “TRAFFIC TRAFFIC” Aural Warning

26
Q

Symbol “Red Filled Square”

A

Resolution Advisory (RA) Red Filled Square - Position/closure rate requires corrective or preventative action. Visual & Aural Vertical Guidance (CLIMB CLIMB CLIMB) and visual maneuvering advisory on Vertical Speed Indicator.

27
Q

Plus + sign indicates?

A

Intruder above aircraft, data tag should include altitude in hundreds of feet

28
Q

Vertical arrow to the right of the intruder indicates?

A

Vertical speed of the intruder is 500 feet or greater per min

29
Q

What color is a Resolution ( RA ) ?

A

Resolutions are RED

30
Q

TA MODE is what?

A

Traffic Advisory mode: range, bearing, and relative altitude. Provides awareness but does not issue Resolution Advisories.

31
Q

RA MODE is what?

A

Resolution Advisory mode: TA information displayed, and will issue visual & audio Resolution Advisories for traffic determined a threat.

32
Q

TCAS vertical display NORM provides?

A

NORM = from +2700 feet to -2700 feet

33
Q

TCAS vertical display ABV provides?

A

ABV = from +8700 feet to -2700 feet

34
Q

TCAS vertical display BLW provides?

A

BLW = from +2700 feet to -8700 feet

35
Q

Maximum number of intruders displayed on PFD HSI?

A

Five intruders max at one time. RA’s take priority over TA’s

36
Q

System will command what FPM climb or descent?

A

1500 - 2500 FPM climb or descent, adjust vertical speed to comply

37
Q

What display on the HUD indicates safe area to fly to?

A

The “FLY-TO” box indicates safe area to fly to
