Flaps in Cfg file

[OldCrow]

On a few of my planes, the cfg file shows 3 types of flaps. All planes have [flaps.0], but what's up with [flaps.1] and [flaps.2] shown below??? Do these things do anything? My Mustangs and P-80 has them, and both cfg files are from Mudpond.

[flaps.0] //Trailing Edge Flaps
type = 1
span-outboard = 0.5
extending-time = 5
flaps-position.0 = 0
flaps-position.1 = 11, 282
flaps-position.2 = 22, 270
flaps-position.3 = 33, 258
flaps-position.4 = 44, 246
flaps-position.5 = 55, 240
damaging-speed = 282
blowout-speed = 306
system_type = 1
lift_scalar = 1
drag_scalar = 1
pitch_scalar = 1
[flaps.1] //Leading Edge Flaps
type = 2
span-outboard = 0.5
extending-time = 5
flaps-position.0 = 0
flaps-position.1 = 15
flaps-position.2 = 30
flaps-position.3 = 45
flaps-position.4 = 30
damaging-speed = 282
blowout-speed = 306
system_type = 1
lift_scalar = 1
drag_scalar = 0
pitch_scalar = 0
[flaps.2] //Leading Edge Flaps
type = 2
span-outboard = 0.5
extending-time = 5
flaps-position.0 = 0
flaps-position.1 = 4
flaps-position.2 = 5
flaps-position.3 = 6
flaps-position.4 = 45
damaging-speed = 282
blowout-speed = 306
system_type = 1
lift_scalar = 0
drag_scalar = 1
pitch_scalar = 0

Best ask Sparks over at the Flight Dynamics forum:- http://www.sim-outhouse.com/sohforums/forumdisplay.php?f=42
but looking at the lift_, drag_ and pitch_scalar values, I'd suggest it's to fine-tune and get around some FM shortcomings.

From Mudpond"s Flight Dynamics Workbook:
Flaps Type
1= None
2= Plain
3= Split
4=Slotted
5= Fowler

Basically they are the aerodynamic types of flaps arrangements, with fowler being the most efficient. I am not sure why the main trailing edge flaps would be set to 1. But I would do any changes through AirWrench or Flight Dynamics Workbook, if you have the original .XLS. The Flight Model system uses both the .AIR and .CFG for information.
