Embraer's airplane operations manual was inconsistent with its standard operating procedures manual in relation to speed mode selection. This increased the risk of flight crews departing with the manual speed mode unintentionally selected.
Embraer advised that it will harmonise the contents of the airplane operations manual and its standard operating procedures manual in the first half of 2025. The ATSB welcomes this proposed safety action that will likely address the safety issue. The safety issue will continue to be monitored pending completion of the safety action.
Response by Embraer
Embraer advised that it proposes to align the contents of the airplane operations manual and its standard operating procedures manual in the first half of 2025. This will likely involve removal of the reference to the initial selection of manual mode in the Before start procedure.
