Max allowable power - PT6

[hamil]

Hi,

A clarification, please:

Pratt and Whitney PT6... what does 'max allowable power' mean?

Some colleagues consider it as the maximum continuous or, for 20 seconds, the transient margin. However, other pilots consider move the power levers to the limit (full forward), although reaching "red" values, without any reference about numbers and/or time limitation.

Thanks.
