On windshear takeoff after V1, what is the first action?

• A. Reach VR...Rotate
• B. THR LEVERS...TOGA
• C. DO NOT CHANGE CONFIGURATION
• D. FD ORDERS FOLLOW

Answer: (B)

When windshear is encountered on takeoff after V1, the priority is to maximize thrust to regain airspeed and climb performance as quickly as possible. Moving the thrust levers to TOGA sets the engines to maximum takeoff/go-around thrust, giving you the strongest possible acceleration and improved chances of getting the aircraft cleanly airborne and climbing out of the windshear. Once TOGA is established, you rotate at the appropriate VR to initiate the climb, then continue the windshear recovery procedure as required. Rotating before applying TOGA would delay the needed power, reducing your performance margin in the windshear. Not changing configuration ignores the need for maximum thrust, and simply following flight director orders without establishing TOGA first can leave you underpowered in a hazardous situation.
