Thank you Tim - my mistake missing that.

I'm very much enjoying using this software - thank you for what you have provided to the community.

You are absolutely right TreeTops that was my first mistake. Good spot!

I corrected this by making Unusable=0, but I still get the same result.

Tried putting a couple of numbers in the piston section, that is, unchecked the Turbine / Jet checkbox to reveal Piston Performance fields, and the flightplan starts to reflect these numbers.

It is when the Turbine / Jet Performance fields are used alone that the problem happens.

Also, In the Fuel Reference fields (common to both Piston and Turbine / Jet), I have used pounds per hour. Should they be USG?

Hello, congratulations to all the Plan-G team for a wonderful piece of software!

I've just started playing with Aircraft Profiles and have written one for the Raytheon T-6A Texan.

Unfortunately, when I load this profile and set up a flightplan I get zeros for all the fuel planning parameters.

Tried reading the manual and searching this forum. Tried downloading other folks turbine profiles and they do the same. When I switch back to the Baron profile, all is well again.

Can anyone help me? I'm sure I've missed something obvious!

Pictures (worth a thousand words) are attached.
