krazyj 3 Posted September 21, 2019 Share Posted September 21, 2019 Hi all, Im tinkering with a profile for the X-rotors AW139, and one of the issues I have is that PFPX always tends to select the highest FL, regardless of weather. Being a Helicopter this is not always the best scenario, is there a way I can preset the profile to select an altitude/FL somewhere in the middle, without having to manually change it every time I plan a flight. cheers Link to comment Share on other sites More sharing options...
srcooke 421 Posted September 21, 2019 Share Posted September 21, 2019 Perhaps post your performance file so that those with greater knowledge could take a look and maybe advise. PFPX calculates the altitude based on winds/profile data and optimization method and certainly for airliners the alt is not maximum. Link to comment Share on other sites More sharing options...

srcooke 421 Posted September 21, 2019 Share Posted September 21, 2019 You'll need more knowledgeable advice than I can give but your cruise entry contains the same speed/fuel flows for all altitudes.

krazyj 3 Posted September 21, 2019 Author Share Posted September 21, 2019 yes, the fuel consumption varies very little for a helicopter as the engines are basically running at full rated speed throughout. but as mentioned above the files are a work in progress and needs to be tinkered as required to dial in the actual fuel consumption as programmed by the addon and yes I am refering to the guide, but helicopters are a special breed so it falls a little beside the target of the guide but appreciate the input Srcooke Link to comment Share on other sites More sharing options...
krazyj 3 Posted September 22, 2019 Author Share Posted September 22, 2019 @FlightSimSoft.com care to shed some light on this, surely the developer can clarify if this is an option or not thanks Link to comment Share on other sites More sharing options...
