Although the crew had to deal with a further stall warning as they returned to Perth, the Virgin Australia A320 plane landed without incident (file photo). Blocked drain holes which stopped water being discharged caused false airspeed warnings in a Virgin Australia plane, forcing it to return to Perth, an investigation has found. The Virgin Airbus A320 was climbing away from the Perth airport in September 2015 when its autothrust and autopilot systems disconnected and multiple alerts were generated. Although the crew had to deal with a further stall warning as they returned to Perth, the plane landed without incident. "Modern aircraft with multiple interacting systems can have many layers between the source information and the flight crew," the safety bureau said in its report.
