GO-AROUND PHASE

4 GO AROUND WITH FD ON
The SRS mode guides the aircraft with the highest speed of VAPP or IAS at time of TOGA selection (limited to maximum of VLS +25 with all engines operative or VLS +15 with one engine inoperative with FMS 2) until the acceleration altitude where the target speed increases to green dot.
Some FMS misbehaviour may prevent this automatic target speed increase. Should this occur, pulling the FCU ALT knob for OP CLB manually disengages SRS mode and allows the target speed to increase to green dot. It should be noted however, that the target speed increases to green dot speed as soon as ALT* mode engages when approaching the FCU clearance altitude.
The GA TRK mode guides the aircraft on the track memorised at the time of TOGA selection. The missed approach route becomes the ACTIVE F-PLN provided the waypoints have been correctly sequenced on the approach. Pushing for NAV enables the missed approach F-PLN to be followed. Above the go-around acceleration altitude, or when the flight crew engages another vertical mode (CLB, OP CLB), the target speed is green dot.
GO AROUND WITH FD OFF
The PF maintains 15 ° of pitch.
The crew will not select the FD ON before the acceleration altitude, since this would not activate the SRS mode. (V/S mode would be activated, maintaining the V/S at mode engagement).
At the thrust reduction/acceleration altitude, the crew will set the selected speed to green dot before setting CLB thrust, since the autothrust will activate in selected speed mode.
The crew will then set the FD ON , and select the appropriate modes.
