CFS2 Configuration file
The Aircraft CFG FILE

[CONTACT_POINTS] Section

The parameters in this section let you configure and adjust the way your aircraft reacts to different kinds of contact, including landing gear contact and articulation, braking, steering, and damage caused by excessive airspeed or combat operations. You can also configure each contact point independently and there is no limit to the number of points you can add.

NOTE
When importing an aircraft that does not contain this data set, CFS2 will generate the data from the AIR file the first time the aircraft is loaded, then write it to the aircraft.cfg file.

Here is a sample [CONTACT_POINTS] section ...

[CONTACT_POINTS]
point.0 = 1, -17.69, 0.00, -3.74, 3200.0, 0, 0.50,180.0, 0.25, 2.5, 0.90, 1.0, 4.00, 0, 0, 200

The parameters (separated by commas) are ...

point.0= 1, -17.69, 0.00, -3.74, 3200.0, 0, 0.50,180.0, 0.25, 2.5, 0.90, 1.0, 4.00, 0, 0, 200

contact_point_number, used to reference the contact point. Numbers begin with "0" and increase for as many points as you need to define.

point.0 = 1, -17.69, 0.00, -3.74, 3200.0, 0, 0.50,180.0, 0.25, 2.5, 0.90, 1.0, 4.00, 0, 0, 200

classdefines the type of point being defined.

   0 = Unused or ignore
   1 = Landing Gear wheel
   2 = Scrape point

point.0 = 1, -17.69, 0.00, -3.74, 3200.0, 0, 0.50,180.0, 0.25, 2.5, 0.90, 1.0, 4.00, 0, 0, 200

X, Y, Z coordinates that define the longitudinal, lateral and vertical distance in feet to this point measured from the aircraft Reference Datum Point (0,0,0).

point.0 = 1, -17.69, 0.00, -3.74, 3200.0, 0, 0.50,180.0, 0.25, 2.5, 0.90, 1.0, 4.00, 0, 0, 200

impact_damage_threshold. The aircraft speed in feet per minute at which impact with the ground can cause damage. CFS2 scales this value with the realism setting to allow less tolerance at higher realism settings.

   feet/min = mph*5280/60
   feet/min = (feet/sec)*60

point.0 = 1, -17.69, 0.00, -3.74, 3200.0, 0, 0.50,180.0, 0.25, 2.5, 0.90, 1.0, 4.00, 0, 0, 200

brake_map, used for wheels only to define which brake input drives the brake.

   0 = None
   1 = Left brake
   2 = Right brake

point.0 = 1, -17.69, 0.00, -3.74, 3200.0, 0, 0.50,180.0, 0.25, 2.5, 0.90, 1.0, 4.00, 0, 0, 200

wheel_radius. The radius of the wheel in feet. It's used to correctly animate wheel rotation.

point.0 = 1, -17.69, 0.00, -3.74, 3200.0, 0, 0.50,180.0, 0.25, 2.5, 0.90, 1.0, 4.00, 0, 0, 200

steering_angle. The angle in degrees this wheel can pivot left and right of center. Used on nose wheels and tail wheels to set the maximum wheel pivot angles.

point.0 = 1, -17.69, 0.00, -3.74, 3200.0, 0, 0.50,180.0, 0.25, 2.5, 0.90, 1.0, 4.00, 0, 0, 200

static_compression. The amount the landing gear strut is compressed in feet when at rest on the ground. This value sets the strength of the landing gear. The smaller the number, the "stiffer" the strut. Adjusting this value for a nose wheel/tail wheel aircraft can fix the "bouncy tail" syndrome.

point.0 = 1, -17.69, 0.00, -3.74, 3200.0, 0, 0.50,180.0, 0.25, 2.5, 0.90, 1.0, 4.00, 0, 0, 200

ratio_max_to_static_compression. Used primarily for landing gear strut animation to determine the relative amount of strut compression.

point.0 = 1, -17.69, 0.00, -3.74, 3200.0, 0, 0.50,180.0, 0.25, 2.5, 0.90, 1.0, 4.00, 0, 0, 200

damping_ratio. Used to determine how strut forces are damped.

   0 = Completely undamped (Oscillations continue with a near constant magnitude)
   1 = Critically damped (Little or no oscillation)

A negative value increases the magnitude of the oscillations, making ground handling unstable. Damping ratios greater than 1.0 may also cause instability due to excessive damping forces. Typical damping ratios range between 0.65 and 0.95. If this value is not set, CFS2 will use the default values in the aircraft's AIR file.

point.0 = 1, -17.69, 0.00, -3.74, 3200.0, 0, 0.50,180.0, 0.25, 2.5, 0.90, 1.0, 4.00, 0, 0, 200

extension_time. The amount of time in seconds it takes the landing gear to fully extend under normal conditions. Use 0 (zero) for fixed landing gear.

retraction_time. The amount of time in seconds it takes the landing gear to fully retract under normal conditions. Use 0 (zero) for fixed landing gear.

   2 = Left Gear
   3 = Right Gear
   4 = Fuselage Scrape
   5 = Left Wing
   6 = Right Wing
   7 = Aux1 Scrape
   8 = Aux2 Scrape
   9 = Tail Scrape

point.0 = 1, -17.69, 0.00, -3.74, 3200.0, 0, 0.50,180.0, 0.25, 2.5, 0.90, 1.0, 4.00, 0, 0, 200

airspeed_limit. The speed in knots at which landing gear extension becomes inhibited. If set to 0 (zero), this function is ignored. This is a function of the Realism settings. Omit this number for fixed landing gear.

point.0 = 1, -17.69, 0.00, -3.74, 3200.0, 0, 0.50,180.0, 0.25, 2.5, 0.90, 1.0, 4.00, 0, 0, 200

damage_airspeed. The speed in knots above which extended landing gear is damaged. This is a function of the Realism settings. Omit this number for fixed landing gear.

There are three other contact reaction parameters that may be included in the [CONTACT_POINTS] section:

max_number_of_points = 16
static_cg_height = 5.908
static_pitch = 12.2518

max_number_of_points = 16

This parameter sets the maximum number of contact points CFS2 will look for in the [CONTACT_POINTS] section. If this value is not set, CFS2 uses the default value of 25.

static_cg_height = 5.908

This parameter sets the vertical height in feet of the aircraft center of gravity when the aircraft is sitting at rest on the ground. This value is used by CFS2 to properly place the aircraft on the ground at engine start, when slewing and at any other time the simulator in not determining aircraft position.

static_pitch = 12.2518

This parameter sets the pitch angle in degrees of the aircraft centerline when the aircraft is sitting at rest on the ground. This value is used by CFS2 to properly place the aircraft on the ground at engine start, when slewing and at any other time the simulator in not determining aircraft position.
