Actually it's not Airbus or Boeing thing but aerodynamics of ground effect comes in play which is same for both. In ground effect the wing is more efficient and CL Max, so is stalling AoA is reached at lesser AoA than when outside ground effect. The thrust may be idle and aircraft path downwards. When you go around from here AC transits out of ground effect the thrust is coming up, speed may be lower than Vref and aircraft sinking. Raising flap will add to this deficiency. If you raise AoA it may reach stall AoA. Air Canada 646 stalled and was destroyed. G650 crash on takeoff killed two test pilots. I want some expert views in this.
