DH8C Powerplant Limitations

Hello everyone,
Does anybody know if there is a minimum take-off power for the Dash-8-Q300?
Thanks!

There's no specific limitation in the flight manual I have. The company I flew them for didn't do reduced power take-offs so the question didn't come up.

How do you calculate a reduced power in a turboprop. Flex, assumed temperature, fixed derate like in the jets?

Assumed temperature works.

Thanks!

Thank you all for your replies!

At my company where I fly, they assume it's 82% as minimum take-off power in high elevations, hot temperatures but I couldn't find that witten in any official manual from the manfacturer.
