The answer to your para1is in FCTMGENERAL GUIDELINES
The answer to your para1is in FCTMGENERAL GUIDELINES
- Predictive windshear@ warning (“WINDSHEAR AHEAD" and "GO AROUND WINDSHEAR AHEAD" aural alerts, associated with the W/S AHEAD that appears on the PFDs), reactive windshear warning ("WINDSHEAR WINDSHEAR WINDSHEAR" aural alert, associated with the WINDSHEAR that appears on the PFDs) and windshear detected by the flight crew, request immediate actions.
The following recommendations apply for takeoff after V1 and when airbone (including approach and go around phases):- The flight crew must set TOGA thrust and should follow SRS orders (if necessary pull the sidestick fully back).
If the FD bars are not displayed, the flight crew should move toward an initial pitch attitude of 17.5 °. Then, if necessary, to prevent a loss in altitude, increase the pitch attitude. - If the AP is engaged, the flight crew should keep it engaged. The AP disengages if the angle of attack value goes above αPROT
- The flight crew should monitor the flight path, the speed and the speed trend.
- The flight crew must set TOGA thrust and should follow SRS orders (if necessary pull the sidestick fully back).
- Suspected windshear (upon ATC or traffic notification or flight crew observation) and predictive windshear@ caution (“MONITOR RADAR DISPLAY" aural alert, associated with W/S AHEAD that appears on the PFDs) request anticipation of the flight crew to be prepared for a possible windshear
So it seems that FLEX T/O is permitted in case of suspected w/s , and if suspect is confirmed by crew or alert - use TOGA ,otherwise use flex...
There is a list in FCTM that gives precautionary measures for appch with suspected w/s. I thought that there is something similar for T/O in manuals. Thanx.

Hi Sergei,
Are You referring to the fact that when the predictive windshear procedure migrated from the FCOM to the FCTM the wording and format changed?
In the "old" FCOM PRO-SUP-91 Adverse Weather the use of TOGA as a precaution was specifically mentioned. In the FCTM the use of TOGA is related to the crew and/or PWS detection of the windshear.
Is that what You were thinking about?
Cheers.

I just wanted to highlight the priorities of SRS. FCOM doesn't specify this.
