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.

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
Symbol "Yellow Filled Circle"
Traffic Advisory (TA) Yellow Filled Circle - Range/Closure rate warrants special attention. "TRAFFIC TRAFFIC" Aural Warning
26
Symbol "Red Filled Square"
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
Plus + sign indicates?
Intruder above aircraft, data tag should include altitude in hundreds of feet
28
Vertical arrow to the right of the intruder indicates?
Vertical speed of the intruder is 500 feet or greater per min
29
What color is a Resolution ( RA ) ?
Resolutions are RED
30
TA MODE is what?
Traffic Advisory mode: range, bearing, and relative altitude. Provides awareness but does not issue Resolution Advisories.
31
RA MODE is what?
Resolution Advisory mode: TA information displayed, and will issue visual & audio Resolution Advisories for traffic determined a threat.
32
TCAS vertical display NORM provides?
NORM = from +2700 feet to -2700 feet
33
TCAS vertical display ABV provides?
ABV = from +8700 feet to -2700 feet
34
TCAS vertical display BLW provides?
BLW = from +2700 feet to -8700 feet
35
Maximum number of intruders displayed on PFD HSI?
Five intruders max at one time. RA's take priority over TA's
36
System will command what FPM climb or descent?
1500 - 2500 FPM climb or descent, adjust vertical speed to comply
37
What display on the HUD indicates safe area to fly to?
The "FLY-TO" box indicates safe area to fly to
