12RomeoCharlie Posted June 12, 2022 Report Share Posted June 12, 2022 I am building a Fly With Lua HUD and have everything working as desired, but struggling to find the source (or means to calculate) the TRQ% indication in the MFD. I've tried all sorts of calculations (e.g. engine torque divided by max torque, etc being careful to normalize metrics) but failing. Any thoughts? (TBM900 1.1.13) Thanks.

Ch.Cole Posted June 13, 2022 Report Share Posted June 13, 2022 (edited) I built something with DataRef("Torquenm", "sim/cockpit2/engine/indicators/torque_n_mtr","readonly",0) and imgui.TextUnformatted("Torque : " .. math.floor(Torquenm/30) .. "%") I just did some checks: The dataref-formula and the MFD match at values > 35% Lower than that, the dataref shows a lower value 10/16 20/25 30/32 Edited June 13, 2022 by Ch.Cole Checked it...

12RomeoCharlie Posted June 13, 2022 Author Report Share Posted June 13, 2022 Thank you. I am currently using a poorer surrogate, "sim/flightmodel2/engines/throttle_used_ratio" and seeing similar behavior. The "torque" dataref is a better starting place, so I will play with that. Perhaps with some math or table lookups to calibrate the reported TRQ% indication at the lower power levels. Not sure where the fancy math is being performed by the aircraft to provide the reported torque. Appreciate the response. Quote Link to comment Share on other sites More sharing options...
