Thai cleared for takeoff with Air India still on the runway, what the investigators missed out at Delhi incident
Interestingly, there was a bigger surprise waiting when I read the report. Apparently, the Thai Airways aircraft was cleared for takeoff from Runway 29 at Delhi by the air traffic control. Even before the preceding aircraft AI014 had vacated the runway. Why did the investigators fail to notice this error?
Background Startle and surprise are often cited as potentially contributing factors to aircraft incidents due to their possible negative effects on flight crew performance. In the past, these terms have often been used interchangeably; however, there are distinctive conceptual, behavioural, and physiological differences between the startle reflex and the surprise emotion. The prevalence of startle and surprise on the flight deck has been investigated by examining voluntary incident reports in the Aviation Safety Reporting System (ASRS). Surprise has been found to be more prevalent than startle. Send article as PDF
The root cause of this event was the initial difficulty to control the aircraft laterally due to the rapid asymmetric thrust increase at low speed. We will analyse this phenomenon in the following paragraphs and explain how the pilots can ensure a symmetric thrust increases to ease the lateral control of the aircraft in the early takeoff roll.
French (BEA) study on approach and go-around reveals that many pilot monitoring (PM’s) do not know where and when to look during a go-around.
