Alliance Airlines flight crews were regularly changing the speed selector knob setting during the take‑off run. This was contrary to Embraer's guidance, and Alliance Airline’s own standard operating procedures manual. This increased the risk of distraction during a critical phase of flight.
Flight crews will receive targeted instruction emphasising that no adjustments to the speed selector knob are to be made during the take-off roll, with compliance monitored through analysis of flight data and assessed during recurrent check and training.
The ATSB is satisfied that these actions adequately address the safety issue.
Response by Alliance Airlines
Alliance Airlines advised that flight crews will receive targeted instruction emphasising that no adjustments to the speed selector knob are to be made during the take-off roll. This will be reinforced during initial, recurrent and line check assessments. Compliance with this policy will be monitored through the collection and analysis of flight data and will be assessed during recurrent simulator training and annual line proficiency checks.
