What would you do on approach if selecting flaps 2 and the ECAM caution F/CTL FLAPS LOCKED - WING TIP BRAKE ON came on

A

Pull speed

DO NOT move the flap lever
Discontinue the approach
If below FCU altitude, it would need to be a go around, however because the flap lever can’t be moved, briefly confirm both pilots understand it will be a go around with no flap movement, then say something like “Go around maintain config”, and follow the missed approach. Aviator, Navigate, Communicate, then consider ECAM.

ECAM, then consult QRH landing with slats or flaps jammed
