Power Trend Checks, Topping Checks, Power Availability Checks?
The RFM for the 412 has a procedure for doing Power Assurance Checks...the maintenance manual has the procedure for the topping checks...there are several field expedient checks for determining power actually available for pinnacle landings, etc.....which one you looking for?
