Mmmmm ....
Geoffers ....
I am with Aser on the issue of Torque Limiter operations (as Is the company I fly with).
Whilst I do not have a copy of the RFM or QRH with me atm ... I do not recall anywhere in those documents where there is a limitation on its (Torque Limiter) operation. Yes there is an explanation of it operation with regard limiting values (also saying that for OEI flight its operation is inhibited) ... but nowhere does it say your NOT to use it for any particular condition of flight.
Please correct me if I am wrong!
Cheers
