Perhaps the aircraft has windshear recovery guidance in the FD system- (TOGA Windshear). If so then the FD should always be followed.
Most recovery control laws will consider the aircraft’s altitude and speed (total energy), and then compute a compromise FD command between not loosing altitude and minimising the time in the location. However, in a severe micoburst, the system’s optimisation would (should) direct a climb at the ‘eyebrow’ attitude thus minimise the likelihood of ground contact.
