JET_density_on_ff_table

Hello,


I have added this line in my engines.cfg, yet the engines are still using SL fuel flow throughout the flight:

JET_density_on_ff = 0.002378:1.0, 0.002049:0.8177, 0.001756:0.6638, 0.001496:0.5342, 0.001267:0.4271, 0.001066:0.3376, 0.000890:0.2646, 0.000737:0.2047, 0.000585:0.1575, 0.000460:0.1243

Anything wrong with it?


Thanks!

Hello @boufogre

Sorry for the delay in my answer.
Maybe this is not clear enough in the doc but the table needs to go from low to high densities.
Replacing your table with this should work:
jet_density_on_ff_table = 0.000460:0.1243, 0.000585:0.1575, 0.000737:0.2047, 0.000890:0.2646, 0.001066:0.3376, 0.001267:0.4271, 0.001496:0.5342, 0.001756:0.6638, 0.002049:0.8177, 0.002378:1.0

Hello @FlyingRaccoon (I will keep trying this until it works),

I have just tested and indeed, that was the solution. I confirm you that it is not clear at all from the documentation that density has to be put in an increasing order.

Maybe it should be specified.

Thanks again for the help.
