“WINDSHEAR TOGA”
SURV MONITOR RADAR DISPLAY(AMBER CAUTION)
Triggering Conditions:
The Predictive Windshear System (in the SURV system) detects windshear (predictive
windshear) during the approach phase.
The W/S AHEAD caution on the PFDs
- The associated MONITOR RADAR DISPLAY aural alert
- The location of windshear on the ND.
APPLY PROCEDURE FOR “SUSPECTED WINDSHEAR”
BEFORE TAKEOFF
Delay takeoff, until weather conditions are better.
Confirm if the weather conditions are safe for takeoff by:
- Observation and experience
- Checking weather conditions.
MOST SUITABLE RUNWAY …………………………………………………………………………………SELECT
Take into account the location of suspected windshear, when selecting the most suitable runway.
● Before starting the takeoff run:
WEATHER RADAR …………………………………………………………………………………………. CHECK
Press the EFIS CP WX pb to check the weather radar and the PWS display on the ND, and to
ensure that there are no suspected problem areas on the flight path.
TOGA THRUST …………………………………………………………………………………………………..SELECT
Do not use reduced takeoff thrust (i.e. derate or FLEX).
SPEED and SPEED TREND ………………………………………………………………………………MONITOR
During the takeoff run, carefully monitor airspeed and the airspeed trend, for early indications of
windshear.
DURING APPROACH
Delay landing, until weather conditions are better, or divert to another airport.
Confirm if the weather conditions are safe for landing by:
- Observation and experience
- Checking weather conditions.
WEATHER RADAR ……………………………………………………………………………………………….CHECK
Press the EFIS CP WX pb: To check the weather radar and the PWS display on the ND, and to
ensure that there are no suspected problem areas on the flight path.
MOST SUITABLE RUNWAY………………………………………………………………………………… SELECT
Take into account the location of suspected windshear, when selecting the most suitable runway
approach aid.
FLAPS 3 ……………………………………………………………………………………………………………. SELECT
MANAGED SPEED ……………………………………………………………………………………………………USE
Use managed speed during the approach phase.
When in managed speed, the ground speed mini function provides additional speed in strong
wind conditions.
Both FDs……………………………………………………………………………………………………….. CHECK ON
Make sure that both FDs are engaged in approach modes, FPA or V/S modes.
AP……………………………………………………………………………………………………………………………..ON
Engage the autopilot to ensure a more accurate approach, and to rapidly correct any deviation
from the beam, when flying a precision approach, or a NPA with the FLS function.
● If downburst is expected:
VAPP…………………………………………………………………………………………………………INCREASE
Increase the VAPP, that appears on the MFD, up to a maximum of VLS + 15 kt.
SURV GO AROUND, WINDSHEAR AHEAD,(RED WARNING)
Triggering Conditions:
The Predictive Windshear System (in the SURV system) detects windshear (predictive
windshear) during the approach phase.
Apply the following procedure at landing, if the PWS triggers:
- The W/S AHEAD warning on the PFDs
- The associated GO AROUND, WINDSHEAR AHEAD aural alert
- The location of windshear on the ND.
● At landing:
Note: If the flight crew verifies and confirms that there is no risk of windshear, they may
disregard the alert, provided that:
- There are no other signs of possible windshear conditions
- The reactive windshear function is operative.
There are reported cases that specific environments (e.g. obstacles) cause the spurious
triggering of predictive windshear alerts, during either takeoff or landing. However, the
flight crew must always rely on all reactive windshear (i.e. WINDSHEAR) alerts.
GO AROUND…………………………………………………………………………………………………..PERFORM
It is permitted to change the slats/flaps configuration, provided that the aircraft does not enter a
windshear.
L/G UP ……………………………………………………………………………………………………………….SELECT
AP (if engaged) ………………………………………………………………………………………………….KEEP ON
SRS ORDERS ……………………………………………………………………………………………………FOLLOW
If necessary, the flight crew may apply full backstick.
Note: - If the angle-of-attack value goes above alpha prot, the autopilot disengages.
- If the FD is not available, select an initial pitch attitude of 12.5 °. Then, if necessary,
increase the pitch attitude, in order to minimize the decrease in altitude
SURV WINDSHEAR AHEAD, WINDSHEAR AHEAD(RED WARNING)
Triggering Conditions:
The Predictive Windshear System (in the SURV system) detects windshear (predictive
windshear) during the takeoff phase.
Apply the following procedure on ground, before and during takeoff, if the PWS triggers:
- The W/S AHEAD warning on the PFDs
- The associated WINDSHEAR AHEAD, WINDSHEAR AHEAD aural alert
- The location of windshear on the ND.
■ On ground:
Note: If the flight crew verifies and confirms that there is no risk of windshear, they may
disregard the alert, provided that:
- There are no other signs of possible windshear conditions
- The reactive windshear function is operative.
There are reported cases that specific environments (e.g. obstacles) cause the spurious
triggering of predictive windshear alerts, during either takeoff or landing. However, the
flight crew must always rely on all reactive windshear (i.e. WINDSHEAR) alerts.
■ Before takeoff:
TAKEOFF…………………………………………………………………………………………………………DELAY
Delay takeoff, until weather conditions improve.
MOST SUITABLE RUNWAY……………………………………………………………………………. SELECT
When selecting the most suitable runway, take into account the location of predicted
windshear.
■ During the takeoff run:
TAKEOFF……………………………………………………………………………………………………… REJECT
Predictive windshear alerts are inhibited above 100 kt, and until the aircraft reaches 50 ft.
■ When airborne, at initial climb:
THR LEVERS ………………………………………………………………………………………………………… TOGA
It is permitted to change the slats/flaps configuration, provided that the aircraft does not enter a
windshear.
AP (if engaged)…………………………………………………………………………………………………. KEEP ON
SRS ORDERS…………………………………………………………………………………………………… FOLLOW
Note: If the angle-of-attack value goes above alpha prot, the autopilot disengages.
SURV WINDSHEAR, WINDSHEAR,WINDSHEAR (RED WARNING)
Triggering Conditions:
The PRIMs detect windshear (reactive windshear).
Both PFDs display the WINDSHEAR warning, during the takeoff and landing phases. This warning is
associated with a WINDSHEAR, WINDSHEAR, WINDSHEAR aural alert.
If windshear is detected, either by the systems, or by the flight crew, apply the following recovery
techniques:
■ On ground, at takeoff:
During the takeoff roll, WINDSHEAR, WINDSHEAR, WINDSHEAR alert is inhibited. Windshear
recognition is based on the flight crew observation.
● Before V1:
If there are significant variations in airspeed, and in airspeed trend below the indicated V1,
reject the takeoff.
If windshear occurs during the takeoff roll, the aircraft may reach V1 later (or sooner) than
expected. The flight crew should ensure that there is sufficient runway remaining to stop the
aircraft, if necessary.
● After V1:
THR LEVERS……………………………………………………………………………………………………. TOGA
REACHING VR ……………………………………………………………………………ROTATE NORMALLY
SRS ORDERS………………………………………………………………………………………………. FOLLOW
■ When airborne, during initial climb, or at landing:
THR LEVERS AT TOGA ………………………………………………………………………. SET OR CONFIRM
AP (if engaged)…………………………………………………………………………………………………. KEEP ON
SRS ORDERS…………………………………………………………………………………………………… FOLLOW
If necessary, the flight crew may apply full backstick.
Note: - If the angle-of-attack value goes above alpha prot, the autopilot disengages.
- If the FD is not available, select an initial pitch attitude of 12.5 °. Then, if necessary,
increase the pitch attitude, in order to minimize the decrease in altitude.
DO NOT CHANGE CONFIGURATION (SLATS/FLAPS, GEAR) UNTIL OUT OF WINDSHEAR.
CAREFULLY MONITOR FLIGHT PATH AND SPEED.
RECOVER SMOOTHLY TO CLIMB, WHEN OUT OF WINDSHEAR.
