KNKT.15.12.28.04 On 21 December 2015, an Embraer 195 crew continued a significantly unstable approach which included prolonged repetition of 'High Speed' and a series of EGPWS Alerts which were both ignored and which culminated in a high speed late touchdown which ended in a 200 metre overrun. The Investigation attributed the event to poor flight management and noted the systemic lack of any effective oversight of pilot operating standards compounded in the investigated event by the effects of a steep flight deck authority gradient and the failure to detect anomalies in the normal operating behaviour of both the pilots involved.
