Narrative:
After receiving line-up & wait instructions from ATCT on runway 18R; airport experienced a radical wind shift with convective activity near the field. We were instructed to taxi to runway 36L and were told that a wind shear alert had been issued. As we taxied toward 36L the captain requested a re-computation of the takeoff data using the wind shear profile. We discussed the steps in using the wind shear profile and the appropriate changes were made to the cockpit setup to reflect the new runway and wind shear profile. Specifically we discussed the pilot monitoring (pm) switching to flight path vector (fpv) after takeoff go-around (toga) was selected. Once cleared for takeoff (winds ~320/21g31) the captain advanced the throttles; stabilized the power; selected toga and stated 'set max power'. Shortly after toga was selected; while the throttles were being driven to the takeoff setting I selected fpv on my primary flight display (pfd). The engines reached takeoff thrust and I looked at my display in anticipation of stating 'max power set; speed reference system (srs); 80 kts....etc'. Instead I said 'max power set; no srs' because of the blank flight mode annunciator (FMA)s with the exception of the thrust display. Due to the wind and the slower acceleration of the PW4100 series engines; the aircraft was already well beyond 80 knots. The captain announced 'reject'; brought the throttles to idle and maximum braking was initiated by the autobrake system. I announced 'spoilers' and the aircraft was brought to a rapid stop. I estimate that the reject occurred at approximately 105-110 knots. We informed the tower of the rejected takeoff; cleared the runway; and ran the rejected takeoff (rejected takeoff) checklist and the after landing checklist. We coordinated with ATCT to find a suitable parking position and contacted [company] for appropriate guidance regarding the high speed rejected takeoff. We were instructed to return to the gate for a maintenance inspection and for refueling as we were approaching our rqr fuel. Brake fans were placed on in accordance with (in accordance with) ECAM and the hottest brake approached 380C. We proceeded back to parking without incident.

That procedure drove our decision to have the pm utilize fpv after toga was selected. The fact that the fpv selection eliminates most displayed information on the FMA of the selected side was unanticipated.

Title: An A300 First Officer (FO) reported the Captain initiated a rejected takeoff when the FO announced 'No SRS' at about 105 kts on the takeoff roll.
Narrative: After receiving Line-Up & Wait instructions from ATCT on Runway 18R; airport experienced a radical wind shift with convective activity near the field. We were instructed to taxi to Runway 36L and were told that a wind shear alert had been issued. As we taxied toward 36L the Captain requested a re-computation of the takeoff data using the wind shear profile. We discussed the steps in using the wind shear profile and the appropriate changes were made to the cockpit setup to reflect the new runway and wind shear profile. Specifically we discussed the Pilot Monitoring (PM) switching to Flight Path Vector (FPV) after Takeoff Go-Around (TOGA) was selected. Once cleared for takeoff (winds ~320/21G31) the Captain advanced the throttles; stabilized the power; selected TOGA and stated 'set max power'. Shortly after TOGA was selected; while the throttles were being driven to the takeoff setting I selected FPV on my Primary Flight Display (PFD). The engines reached takeoff thrust and I looked at my display in anticipation of stating 'Max power set; Speed Reference System (SRS); 80 kts....etc'. Instead I said 'Max power set; no SRS' because of the blank Flight Mode Annunciator (FMA)s with the exception of the THRUST display. Due to the wind and the slower acceleration of the PW4100 series engines; the aircraft was already well beyond 80 knots. The captain announced 'reject'; brought the throttles to idle and maximum braking was initiated by the autobrake system. I announced 'spoilers' and the aircraft was brought to a rapid stop. I estimate that the reject occurred at approximately 105-110 knots. We informed the tower of the rejected takeoff; cleared the runway; and ran the Rejected Takeoff (RTO) checklist and the after landing checklist. We coordinated with ATCT to find a suitable parking position and contacted [company] for appropriate guidance regarding the high speed RTO. We were instructed to return to the gate for a maintenance inspection and for refueling as we were approaching our RQR fuel. Brake fans were placed on In Accordance With (IAW) ECAM and the hottest brake approached 380C. We proceeded back to parking without incident. The duty officer was contacted after block in and the Ground Turn Back closed with flight coordination.
