30
TCAS should be operated in which of the following?
All of the answers are correct.

All of the answers are correct.
TCAS is recommended for:
Turbine powered aircraft with a maximum takeoff weight over 5,700 kg or authorized to carry more than 19 passengers.
If the input from the aircraft’s transponder fails:
TCAS will automatically fail.
TCAS is connected to both autopilot and the Flight Management System (FMS) and will not function in the event of the failure of either of these systems.
False; TCAS is not connected to autopilot or the FMS and will function if either fail.
A solid cyan or white diamond on the TCAS traffic display indicates:
Proximate aircraft.
A solid cyan or white diamond on the TCAS traffic display indicates:
Proximate aircraft.
The RA display will:
Display vertical required and prohibited rates on IVSI or PFD.
A red arc on the IVSI display indicates:
A range of vertical speeds which are to be avoided during the issued RA.
An issued RA will always include both a red and green arc on the IVSI display.
False; for RAs which do not require changes in vertical speed, only a red arc will be present.
In a multi-threat situation, TCAS can do any of the following EXCEPT:
Always ensure Altitude Limit (ALIM) separation from all intruders.
What type of transponder is required in both own and intruder aircraft for TCAS to provide optimum safety benefits?
Mode S transponders in both aircraft.
What does a solid red square with a +12 above it and a down arrow to the right indicate?
A resolution advisory has been issued for a descending aircraft above own aircraft with a relative altitude of 1200 feet.
TCAS is designed to provide collision avoidance for aircraft closing horizontally up to 1200 kts. and vertically up to:
10,000 fpm.
In the instance of a multi-threat encounter, TCAS will always provide ALIM separation from all intruders.
False; below ALIM separation is possible in multi-threat encounters.
If two TCAS equipped aircraft declare each other as threats simultaneously, there is a chance both aircraft will select the same sense. When this happens:
The aircraft with the higher Mode S address will detect the selection of the same sense and will reverse its sense.
TCAS will never issue RAs below 1000 feet AGL.
True.
Increase Descent RAs are inhibited below:
1450 feet AGL.
Traffic advisories:
Alert the pilot of the presence of another aircraft that may become a threat.
Resolution advisories recommend:
Maneuvers that increase or maintain existing vertical separation from intruder aircraft.
The main objective of an RA is to achieve safe vertical distance from a threat aircraft. RAs will be issued:
15-35 seconds to CPA.
Which of the following statements is NOT true regarding an “Adjust Vertical Speed, Adjust”?
The vertical rate for this RA should be reduced to 2000 feet per minute.
The “Level off” RA:
All of the answers are correct.
A “Monitor Vertical Speed” RA:
Does not require a change in vertical speed.
An RA which requires a vertical climb rate of 1500-2000 fpm following a “Descend” RA is known as:
Reversal Climb.
An RA which requires a vertical descent rate of 2500-3000 fpm is a(n):
Increase Descent RA.
A “Climb, Climb NOW” RA:
All of the answers are correct.
A corrective RA will advise the pilot to:
Any of these.
Preventive RAs:
Require pilots to avoid certain deviations from current vertical rate.
TCAS will never direct a pilot to cross through an intruder aircraft’s altitude to achieve safe separation.
False; TCAS may direct pilots to cross altitudes and the pilot should comply.
A change in the direction previously issued by TCAS, for example an initial descend RA that changes to a climb RA, is which type of RA?
Reversal.
In the event of a “Climb” or “Descend” RA, pilots should adjust vertical speed to 1500 feet per minute. “Increase Climb” or “Increase Descent” RAs require a vertical speed of:
2500 fpm.
Flying with inoperative TCAS II is permitted.
True; provided it is done in accordance with the applicable MEL provisions.
Maneuvers may be made in response to an issued TA.
False.
When at the gate, TCAS operating mode should be operated in Stand-by which will make own aircraft invisible to:
All of the answers are correct.
If an issued RA conflicts with assigned ATC clearance or instructions, the pilot should comply with the RA anyway.
Yes.
From level flight, proper response to an RA typically results in an overall altitude deviation of 300 to 500 feet. Excessive responses to RAs:
All of the answers are correct.
Pilots should follow the TCAS RA to resolve the immediate traffic conflict in all of the following situations EXCEPT if the RA requires maneuvering contrary to which of the following?
All of the answers are correct.
Disregarding an RA and maneuvering vertically based solely on visual acquisition may result in a loss of safe separation because:
Any of these.
TCAS may be operated in TA-only mode in all of the following circumstances EXCEPT:
In visual conditions while flying in remote areas.
If the Mode S Transponder is fully operational and will reply to ground and TCAS interrogations, but TCAS is in stand-by, then the transponder is set to:
Transponder Mode.
When a pilot selects TA-Only mode, TCAS is placed into sensitivity level 2, meaning:
RAs are inhibited.
Pilots should have an initial vertical speed response time of _____ to a “climb” or “descend” maneuver advisory.
Pilots should have an initial vertical speed response time of _____ to a “climb” or “descend” maneuver advisory.
Operating TCAS on the ground:
All of the answers are correct.
Disregarding RA information may result in:
All of the answers are correct.
When informing ATC of a clearance deviation, the transmission should include the name of the ATC facility, aircraft ID and:
The nature of the TCAS deviation.
ATC will not provide separation to the TCAS maneuvering aircraft until:
At least one of these conditions is met.
Pilots must report all RAs to ATC.
False; only RAs causing deviation from assigned ATC clearance must be reported.
If a flight crew receives a TCAS RA followed by a newly issued and contradictory ATC instruction, the pilot should respond by:
Following the RA and responding to ATC “Unable to comply, TCAS resolution advisory.”
