Emptying fuel tanks with FSUIPC6

Featured Replies

  • Moderator

Flying the Xtreme Prototypes Lear 25 requires the correct amount of fuel to be loaded. It’s calculated by PFPX. Unfortunately getting it loaded into the tanks has always required me to edit the values in the P3D interface which has never been changed from FSX days.

I can use the refuelling option in GSX but the problem is getting the tanks empty in the first place.

Fortunately I’ve got a method of doing that now. It involves using FSUIPC6 to create a set of commands that sets all tanks to zero with one button click. Details here.

All that’s needed now is for more fuel options in GSX. I’ve asked Umberto to consider adding them.

This will apply to any aircraft using the default fuel interface. Funny how you can suddenly think of something after years of using an unsatisfactory method. 🤣

You should bottle your configuration and sell it as a master class.

Not sure I follow your suggestion.

Thanks a lot, Ray! I seldom use the default fuel loader in P3D, but I do use it a lot in FS9 and FSX, and (judging from my experience with FSUIPC), I can easily apply a similar method there (for other purposes I have).

@Luis Hernandez, glad you’ll find it helpful. I tried searching for a third party utility to load fuel and payload bypassing the P3D interface but nothing came up.

Whilst GSX can load fuel there’s nothing for loading passengers. Frustrating.

It’s only for aircraft that use the default fuel entries. PMDG has a custom one.
