I believe there is/was a revised version of the airfile for the ATR 42-300 Avianova by F. S

Hi,Version 2.0 carried a re-worked air file, it's available here in the library (FSC_ATR42_300v20.zip). In my page eureka.ya.com/pacosancas there is a new aircraft.cfg file which fixes a problem which made the plane go up or down when suddenly changing condition levers.If you follow Mr. Cartwright's advice of using the default dash7 air file or any other air file, the pwr mgt gauge will become unusable (not to mention that you will not fly a turboprop but rather a model airplane). The propeller sections in the air file have been carefully calibrated according to the airplane specs and procedures. Just follow the instructions and set the correct NP for each part of the flight.Paco
