Go Around at Orly led to GPWS warnings as the aircraft descended

When the plane was on final for runway 25 at Orly, a Runway Incursion Monitoring and Collision Avoidance System (RIMCAS) warning was activated due to the presence of a bird-control vehicle in the vicinity of the runway safety area. However, the bird-control vehicle was behind the holding point and outside the runway safety area. The erroneous activation of the RIMCAS warning was due to the relocation of the holding point, after work, not being taken into account in the system parameters. Due to the RIMCAS warning and the absence of a reply from the driver of the vehicle, the controller ordered the crew to perform a go-around after they had passed through the decision altitude (DA). The crew carried out the go-around by initially displaying a thrust and a pitch attitude which resulted in a high vertical speed. They then engaged the auto-throttle (A/T) although the autopilot (A/P) was disengaged. The left turn was started late and the high bank angle triggered the “BANK ANGLE” warning. The missed approach altitude was exceeded during the turn. Under the combined effect of a nose-down input from the PF and the A/T reducing the thrust, the plane next re-descended below 2,000 ft. The controller then cleared the crew to climb to 3,000 ft. The crew’s selection of this altitude caused a V/S mode reversion with the instantaneous vertical speed taken as the target speed (-1,100 ft/min).
