212 - FL100 near Malta in summer (ie hot) just hitting the engine limit so torque down by a couple of % ie MCP around 80% Q (though AP limiting it to around 78%) so it's hard to imagine flight conditions where you would get near to 70% Q - maybe equatorial at FL100?

Pitts, regarding the torque limits, I know its complex but do try to keep up! 70% Q now, because one needs to have a reasonable flight duration between HUMS downloads. Once the MOD 45 airborne alert is in place, no point in limiting torque until after a crack is detected. Hopefully not that often, after all we did manage nearly 100,000 hrs in the company and no cracks at all, so its not as if its going to be cracking every other flight! One needs to keep a sense of scale!
