Fuel Flow Reading Mismatch: Analog vs. TDS

[hangar_101]

I noticed that in the Caravan Pro (Black Square) for FS2024 there’s a discrepancy in the fuel flow readings. The analog fuel flow gauge matches the POH values perfectly, but the TDS GTN750Xi shows numbers that are noticeably lower than expected. Does anyone know why there’s such a difference between the two indications?

Given that the difference is 11.6lbs, I suspect the TDS is reading gallons per hour and converting it to AVGAS lbs instead of Jet-A lbs. There is probably a menu option in the TDS to set the aircraft's fuel type.

You can for sure change the fuel options in the external TDS application. I'm pretty sure it defaults to avgas

Thank you all. You both nailed it.

Changed fuel type to Jet-A (external TDS interface)

Issue fixed
