ADVISORY ALERT(TCAS) Flashcards
TRAFFIC ADVISORY ALERT “CALL OUT”
● If AP/FD TCAS mode is armed:”TCAS Blue”
● If AP/FD TCAS mode does not arm:”TCAS, I have control”
PROCEDURE:
Triggering Conditions:The TCAS (in the SURV system) detects a Traffic Advisory (TA).
If the AP/FD TCAS mode is available, the AP/FD TCAS mode arms.
TCAS mode …………………………………………………………………………………………CHECK ARMED (blue)
When the AP/FD TCAS mode arms, the flight crew must be prepared to apply the AP/FD TCAS
procedure in the case of a Resolution Advisory.
If the AP/FD TCAS mode does not arm, the flight crew must be prepared to apply the basic TCAS
procedure in the case of a Resolution Advisory.
● If the A/THR is off:
A/THR………………………………………………………………………………………………………………………..ON
The flight crew should set the A/THR ON to avoid the triggering of the AUTO FLT A/THR LIMITED
alert at the A/THR activation, in the case of a Resolution Advisory.
Do not perform a maneuver based on a TA alone.
RESOLUTION ADVISORY ALERT “CALL OUT”(SAME AS FOR TA)
PROCEDURE:
Triggering Conditions:
The TCAS (in the SURV system) detects a Resolution Advisory (RA).
There are two types of Resolution Advisories (RA):
- Preventive RAs
A preventive RA is announced by the “MONITOR VERTICAL SPEED” aural alert. For more
information on the aural alerts, Refer to 34 / SURV / TCAS / Controls and Indicators / Aural Alerts.
- Corrective RAs.
A corrective RA is announced by one of the following aural alerts:
• “CLIMB, CLIMB”
• “CLIMB, CROSSING CLIMB, CLIMB, CROSSING CLIMB”
• “CLIMB, CLIMB NOW, CLIMB, CLIMB NOW”
• “INCREASE CLIMB, INCREASE CLIMB”
• “DESCEND, DESCEND”
• “DESCEND, CROSSING DESCEND, DESCEND, CROSSING DESCEND”
• “INCREASE DESCENT, INCREASE DESCENT”
• “DESCEND, DESCEND NOW, DESCEND, DESCEND NOW”
• “MAINTAIN VERTICAL SPEED, MAINTAIN”
• “MAINTAIN VERTICAL SPEED, CROSSING MAINTAIN”
• “LEVEL OFF, LEVEL OFF”.
If the AP/FD TCAS mode is available, the AP/FD TCAS mode engages.When the AP/FD TCAS mode engages, the flight crew must apply the AP/FD TCAS procedure.If the AP/FD TCAS mode does not engage, the flight crew must apply the basic TCAS procedure.
AP/FD TCAS PROCEDURE
The flight crew applies this procedure, when a Resolution Advisory (RA) is triggered, and the
AP/FD TCAS mode engages. The AP/FD TCAS mode follows the RA orders.
Always follow the RA orders, even if this results in crossing the intruders altitude, because these
orders ensure the best altitude separation.
CAUTION Be aware that the intruder may have a TCAS, and may maneuver in response to a
coordinated RA order. Therefore, not following an RA order could compromise safe
separation.
● If the AP is off:
FD ORDERS………………………………………………………………………………………………….FOLLOW
The AP can be engaged.
VERTICAL SPEED ……………………………………………………………………………………………MONITOR
If a preventive RA was triggered: Check that the vertical speed remains out of the red area of the
vertical speed scale.
If a corrective RA was triggered: Check that the vertical speed gets out of the red area, and
remains in the green area of the vertical speed scale.
CAUTION If for any reason during an RA, the aircraft vertical speed does not reach the green
area of the vertical speed scale. the Pilot Flying (PF) should disconnect the AP,
and override the FD orders, in order to lead the aircraft vertical speed out of the red
area of the vertical speed scale.
If necessary, the PF must use the full speed range between Vαmax and VMAX.
● If any “CLIMB” aural alert sounds during the final approach:
AP/FD TCAS ORDERS …………………………………………………………………..MONITOR/FOLLOW
GO-AROUND……………………………………………………………………………………………..CONSIDER
If the flight crew performs a go-around, the AP/FD TCAS mode disengages, and the SRS GA
mode engages. The AP/FD does no longer follow the RA orders. The flight crew must follow
the vertical speed indications on the vertical speed scale. The flight crew must then apply the
basic TCAS procedure.
Respect stall, GPWS, or windshear warning.
ATC …………………………………………………………………………………………………………………… NOTIFY
● When “CLEAR OF CONFLICT” aural alert sounds:
The AP/FD TCAS mode disengages. For more information, Refer to DSC-22-FG-70-110-40
Introduction.
AP/FD………………………………………………………………………………………….. MONITOR/FOLLOW
ATC ………………………………………………………………………………………………………………. NOTIFY
LATERAL AND VERTICAL GUIDANCE ……………………………………………………………. ADJUST
The flight crew should engage an appropriate vertical mode, or adjust the vertical speed
target, in accordance with the latest ATC clearance.
SPEED …………………………………………………………………………………………………………. ADJUST
The flight crew should adjust the speed target, and revert to managed speed, as appropriate.
BASIC TCAS PROCEDURE
The flight crew must apply the basic TCAS procedure, if a corrective RA is triggered, and the
AP/FD TCAS does not engage.
Always follow RA orders, even if this results in crossing the intruders altitude, because these
orders ensure the best altitude separation.
CAUTION Be aware that the intruder may have a TCAS, and may maneuver in response to a
coordinated RA order. Therefore, not following an RA order could compromise safe
separation.
AP (if engaged) ………………………………………………………………………………………………………….OFF
FDs…………………………………………………………………………………………………………………………..OFF
Respond promptly and smoothly.
VERTICAL SPEED …………………………………………………………………………. ADJUST or MAINTAIN
Adjust or maintain vertical speed as required, depending on the green area, and/or to avoid the
red area of the vertical speed scale.
Note: Avoid excessive maneuvers while attempting to maintain the vertical speed just outside
the red area of the scale, and within the green area. If necessary, use the full speed range
between Vαmax and Vmax.
Respect stall, GPWS, or windshear warnings.
ATC…………………………………………………………………………………………………………………….NOTIFY
● When the “CLEAR OF CONFLICT” aural alert sounds:
ATC………………………………………………………………………………………………………………..NOTIFY
LATERAL AND VERTICAL GUIDANCE……………………………………………………………..ADJUST
Adjust the lateral and vertical guidance to resume normal navigation, in accordance with ATC
clearance.
AP/FD ………………………………………………………………………………………………………… AS RQRD
If necessary, reengage the AP/FD.
● If any “CLIMB” aural alert sounds during the final approach:
GO-AROUND………………………………………………………………………………………………PERFORM
