Airport; Human Factors; Procedure
On approach to ZZZZ Runway X received a GPWS 'Too Low Flaps' alert. Executed successful go around. A combination of factors all taking place in a relatively short time span created a distraction that resulted in omission of necessary procedures allowing proper configuration of aircraft for landing. ATC interruptions for requested position reports along the approach; heavy accent from foreign language requiring repetitive communications increasing workload; steep descent due to terrain separation requiring intercepting the glide path from above and extending the landing gear earlier than normal to increase drag resulting in a disruption of normal flows. Airbus logic for increasing airspeed along the approach to maintain a desired ground speed creating a distraction as a result of strong and gusty winds. It is important to create additional barriers when changes from expectations have taken place; such as extending the landing gear earlier than anticipated so as to prevent potential omission of required tasks.
