Appendix B: Legacy TelemFFB Documentation¶

Effects Documentation (Legacy)¶

This section attempts to document and explain each of the effects and their settings. It is a work in progress.

A majority of the effects will apply to both DCS and MSFS. Where applicable, each effect setting has a comment in-line with the default setting to indicate which simulator(s) it applies to.

Generic Aircraft Effects (applies to all (or multiple) aircraft types)¶

G-Force Loading Effect¶

Only applies to fixed-wing aircraft

DCS Only (MSFS has built in G forces in the TelemFFB stick force implementation)

The G-Force loading effect simulates the increasing force that is required to pull back on the stick as the g forces increase during a dive pull-out or hard turn.

gforce_effect_enable (yes/no)
- enable or disable the effect
gforce_min_gs (1.0 or greater)
- the g loading where the effect will start playing
gforce_max_gs (greater than gforce_min_gs)
- g loading where the strength will reach > ‘gforce_effect_max_intensity’
gforce_effect_max_intensity (0.0-1.0 or 0%-100%)
- the maximum force applied in relationship to the constant force > slider in VPforce configurator
gforce_effect_curvature (1.0 or greater)
- affects the onset characteristics of the force effect. A value > of 1.0 is a linear increase in force across the defined g > range. Increasing the curvature value will result in a flatter > increase at the beginning of the range followed by an ever > increasing force as the effect approaches the top of the > range.
- Example values (default is 2.2)

Deceleration Effect¶

Monitors the deceleration g-forces on the aircraft and, if the aircraft is on the ground will apply a forward force (away from pilot) equal to the deceleration G force up to, but not exceeding ‘deceleration_max_force’.

deceleration_effect_enabled (yes/no, on/off, 1/0)
- Enable/disable the effect
deceleration_max_force (0.0-1.0)
- Controls the maximum force that can be applied

Damage Effect (DCS)¶

Plays a short random direction, random intensity bump each time damage is detected on the aircraft.

** Can potentially cause performance impact due to large number of calculations required in export script for some aircraft ** Written in a way that will only execute the code in the export script if the feature is enabled in TelemFFB.

damage_effect_enabled (yes/no, 1/0)
- Controls whether the effect is enabled (both in TelemFFB and the > calculations in TelemFFB.lua export script)
damage_effect_intensity (0.0-1.0, %0-%100)
- Controls the intensity of the generated effects. Note that with > the randomized nature of the intensity, some hits will be > lower and some higher than the defined value

Damage Effect (IL-2)¶

Plays a short random direction, random intensity bump each time damage is detected on the aircraft.

damage_effect_intensity (0.0-1.0, %0-%100)
- Controls the intensity of the generated effects. Note that with > the randomized nature of the intensity, some hits will be > lower and some higher than the defined value

AoA Buffeting¶

Runway Rumble/Touchdown¶

Weapons and Countermeasure deployment¶

Speedbrake Motion and Buffeting¶

Gear Motion and Buffeting¶

Flaps Motion¶

Canopy Motion¶

Spoiler Motion and Buffeting¶

Propeller Aircraft Specific Effects¶

Engine Rumble¶

Jet Aircraft Specific Effects¶

After Burner Rumble¶

Jet Engine Rumble¶

AoA Reduction Effect¶

Simulates the increased forward stick pressure that is applied on some fighter aircraft when a critical angle of attack is exceeded. The effect will monitor the AoA and apply a linear force, up to the maximum defined value starting at the ‘start’ AoA and maxing out at the ‘max’ AoA.
