Enhanced Ground Proximity Warning System
WARNING: “PULL UP”, “TERRAIN AHEAD PULL UP”
CAUTION: “TERRAIN AHEAD”
“PULL UP TOGA”
!! DO NOT CHANGE THE CONFIGURATION (SLATS/FLAPS/GEAR) OF A/C UNTIL CLR OF OBSTACLE !!
Emergency Descent
“EMERGENCY DESCENT”
–> If A/THR Not Active -
4. THRUST LEVERS…IDLE
5. SPEED BREAKS ….FULL
TCAS CAUTION
TCAS - Traffic Collision Avoidance System
“TRAFFIC, TRAFFIC”
“TCAS I HAVE CONTROL”
–> If A/THR is off and available:
1. A/THR….ON
!! Do not perform maneuver on TA alone !!
TCAS WARNING (RA)
RA - Resolution Advisory
“CLIMB” / “DESCEND” / “LEVEL OFF”
“TCAS I HAVE CONTROL”
–> All RA, except any CLIMB RA during approach in CONF 3 or FULL:
1. AP… OFF
2. BOTH FDs ….OFF
- WHY? TO GO TO SPEED MODE
3. VERTICAL SPEED…ADJUST OR MAINTAIN
–> Any CLIMB RA during approach in CONF 3 or FULL:
1. GO-AROUND…PERFORM
2. VERTICAL SPEED…MONITOR
3. ATC…NOTIFY “ATC RA”
–> When the “CLR OF CONFLICT” aural alert sounds:

Loss of Braking
when A/SKID & N/W STRG sw goes to OFF the braking system is transferred from the BSCU to the ABCU. PF should release brakes before switch goes to OFF to avoid brutal braking action
“LOSS OF BRAKING”
–> If still no braking:
7. PARK BRAKE …..USE
(Use short successive parking brake applications to stop the aircraft)
Unreliable Speed Indication/ADR Check Procedure
“UNRELIABLE SPEED”
If the safe conduct of the flight is impacted:
1. AP …..OFF
2. A/THR ….OFF
3. FDs ….OFF
Note: When at or above MSA or circuit altitude, level off for troubleshooting.
