Ok, i mean, I wasn't really trying to get into a aviation arguement. All the materials on the J41 say that the 9 flaps speed is 200. The
tutorial flight provided by PMDG says to extend them as the airplane slows under 200 KIAS. The plaque inside the VC says its 200.
I extend them at between 190 and 200 in order to help the plane slow down during approach.
I guess what I'm really asking then, is how did FSPAX get 190 as the Vfe speed? I don't see that number anywhere in the config. the
line referenced in the help section (where FSPAX gets VFE from) is the "flaps blowout"

This is the reported Vfe

The circled text says that Vfe is found at the blowout speed in the .cfg. But if you look at the .cfg, the speed at the blowout line is actually
210.
[flaps.0] // Main section all
type = 1
span-outboard = 0.65
extending-time = 8.333
lift_scalar = 1.00
drag_scalar = 1.00
pitch_scalar = 1.00
damaging-speed = 205
blowout-speed = 210
flaps-position.0 = 0, 250
flaps-position.1 = 9, 200
flaps-position.2 = 15, 160
flaps-position.3 = 25, 140
[flaps.1] // Correct LIFT 0-15
type = 1
span-outboard = 0.65
extending-time = 8.333
lift_scalar = 1.0
drag_scalar = 0.00
pitch_scalar = 0.00
damaging-speed = 205
blowout-speed = 210
flaps-position.0 = 0.0
flaps-position.1 = 7.927
flaps-position.2 = 2.703
flaps-position.3 = 0.000
[flaps.2] // Correct DRAG 25
type = 1
span-outboard = 0.65
extending-time = 8.333
lift_scalar = 0.0
drag_scalar = 1.00
pitch_scalar = 0.00
damaging-speed = 205
blowout-speed = 210
flaps-position.0 = 0.0
flaps-position.1 = 2.0
flaps-position.2 = 0.0
flaps-position.3 = 6.0
Setting aside best piloting practices, and whether is prudent or not to actually extend the flaps at that speed, why is FSPax getting the
wrong number according to the .cfg?
Consider it a question about how FSpax works rather than a piloting question if that helps.
