Where must personnel be stationed during the operation of ATMs?

During the operation of Automatic Temperature Management Systems (ATMs) on an aircraft, it is critical for personnel to be stationed at the Flight Engineer (FE) station. This is because the FE station typically has direct access to the controls and monitoring systems necessary to operate and manage the ATM effectively. The qualified operator at this station is trained to handle the complexities of the ATM, responding to any changes or issues as they arise, ensuring the system functions as intended and that safety protocols are maintained.

Being at the FE station allows the operator to monitor essential parameters, make real-time adjustments, and coordinate with other crew members who may be involved in the operation. This coordination is vital for the safe and efficient functioning of the aircraft systems during operations that involve ATMs.
