But at which constellation is the system changing from AEO to OEI-Limits respective OVERLIMIT Indication?
and your other questions re Tq etc.
There is no changeover to OEI limits, they're on the FLI all the time, it's only the start limits that appear & disappear. The Flight Manual tells you that the 2.5 min countdown timer activates as soon as either engine exceeds OEI MCP - but it still stands that taking one engine over OEI MCP, whilst the other is producing power, will result in a XMSN over-torque.
