Bell 206 family

Hydraulically assisted cyclic controls with selected friction and trim behaviour, plus two-blade rotor cues.

Meet the aircraft

Bell reworked an unsuccessful military observation-helicopter proposal into the commercial JetRanger. The resulting 206 family became widely used for passenger transport, observation and utility work. The familiar single-engine versions use a two-bladed main rotor.

The 206B JetRanger and stretched 206L LongRanger are separate branches of that story. Their cabins, engines and equipment are not identical. Cowan documents each model's trim, autopilot and stability-assistance features separately.

The simulator model and controls

Bell reworked an unsuccessful military observation-helicopter proposal into the commercial JetRanger. The resulting 206 family became widely used for passenger transport, observation and utility work. The familiar single-engine versions use a two-bladed main rotor.

This starting point selects Bell 206B3 JetRanger. Its aircraft-level settings do not select a particular developer’s custom systems.

How this profile feels

Spring resistance builds with the selected airspeed response. A separate aerodynamic term adds speed-dependent control load.

Local force trim holds the selected hardware centre. Autopilot following is off.

Cyclic damping is on. Its configured gain is 0.35; it resists hardware motion separately from the spring and aircraft stabilization.

Controls and trim

The Bell 206B-3 flight manual describes adjustable cyclic and collective friction, together with magnetic brakes and force-gradient springs in its cyclic force-trim system. CowanSim's 206B3 and longer-cabin 206L3 have separate manuals and optional HeliSAS procedures. FlyInside and DreamFoil implement different dynamics and stability options. A software trim-release command, sound or stability setting does not provide a continuous physical cyclic-neutral position.

About the values

The gains are normalized profile settings. They describe the chosen effect balance; hand force depends on the device and its output limits. IAS references are tuning values rather than operating limits. Physical acceptance of this revision remains pending.

Documentary review and sources

These decisions describe the documentary basis and remaining gaps for this revision. Aircraft documentation and a starting setting describe different kinds of evidence.

SettingStarting valueWhat it controls and why
Spring strengthStarting value0 What it controls and whyMagnetic brakes and force-gradient springs provide mechanism context for cyclic centering; longer cabin or rotor audio does not establish a heavier cyclic. The baseline spring is 0. Its low-speed blend reaches baseline strength at 52.5 KIAS.
Master force gainStarting value0.85 What it controls and whyScales overall profile strength while preserving effect balance, subject to device and output limits.
Profile force gainStarting value0.35 What it controls and whyThe aerodynamic-load gain is 0.35 with an indicated-speed reference of 105 KIAS. This supplies speed-dependent loading alongside the spring.
Force tuning speed/referenceStarting value105.0 ktWhat it controls and whySets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit.
Spring response reference speedStarting value52.5 ktWhat it controls and whySets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it.
Aileron force scaleStarting value1 What it controls and whyRoll and pitch aerodynamic scales are 1 and 1, respectively. They set the aerodynamic axis balance. No custom spring-travel curve is enabled.
Elevator force scaleStarting value1 What it controls and whyScales pitch aerodynamic loading; pitch spring travel and trim responses are separate settings.

Estimated starting settings · revision 2
SettingStarting valueWhat it controls and why
Spring strengthStarting value0 What it controls and whyMagnetic brakes and force-gradient springs provide mechanism context for cyclic centering; longer cabin or rotor audio does not establish a heavier cyclic. The baseline spring is 0. Its low-speed blend reaches baseline strength at 52.5 KIAS.
Spring deadbandStarting value0.02 What it controls and whySets travel around the centre before the baseline spring resists. Smaller values engage it sooner.
Profile force gainStarting value0.35 What it controls and whyThe aerodynamic-load gain is 0.35 with an indicated-speed reference of 105 KIAS. This supplies speed-dependent loading alongside the spring.
Master force gainStarting value0.85 What it controls and whyScales overall profile strength while preserving effect balance, subject to device and output limits.
QBlend EnabledStarting valueEnabled What it controls and whyAllows baseline spring strength to rise with indicated airspeed where the control law permits it.
QSpring Minimum FactorStarting value1 What it controls and whySets low-speed spring strength as a fraction of baseline when blending is enabled. One keeps full strength.
QSpring Start KnotsStarting value14.7 ktWhat it controls and whySets the IAS where the low-speed spring blend starts rising. This is a feel threshold, not a flight limit.
Spring response reference speedStarting value52.5 ktWhat it controls and whySets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it.
Force tuning speed/referenceStarting value105.0 ktWhat it controls and whySets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit.
Airspeed spring stiffening gainStarting value0 What it controls and whyAdds permitted spring resistance above the full-blend speed. Zero removes this high-speed increase.
Airspeed spring stiffening limitStarting value5 What it controls and whyLimits the squared airspeed ratio used for high-speed spring stiffening; it is not a device-force cap.
Aileron force scaleStarting value1 What it controls and whyRoll and pitch aerodynamic scales are 1 and 1, respectively. They set the aerodynamic axis balance. No custom spring-travel curve is enabled.
Elevator force scaleStarting value1 What it controls and whyScales pitch aerodynamic loading; pitch spring travel and trim responses are separate settings.
Output force limitStarting value0.55 What it controls and whyCaps directed-force output. Native spring effects and device limits remain separate.
Trim feelStarting valueDisabled What it controls and whyRetained for compatibility and group membership. Trim relief, rather than this flag, controls centre movement.
Trim reliefStarting valueDisabled What it controls and whyAllows trim relief with supported control law and valid telemetry. Axis authorities set its amount.
Elevator AuthorityStarting value0.3 What it controls and whyScales supported pitch-trim relief and permitted centre movement. Zero removes pitch response.
Aileron AuthorityStarting value0.3 What it controls and whyScales supported roll-trim relief and permitted centre movement. Zero removes roll response.
Force Trim EnabledStarting valueEnabled What it controls and whyAn enabled local latch approximates holding a hardware neutral. CowanSim's SAS-dependent software trim and the aircraft's magnetic-brake system remain separate scope. Local force trim is on. It holds a selected spring centre with strength 0.55.
GLoad EnabledStarting valueDisabled What it controls and whyAllows load-factor changes to modify permitted spring laws. Passive fly-by-wire feel can suppress it.
Rate Damping EnabledStarting valueEnabled What it controls and whyEnables rate damping with the configured coefficients and control law.
Autopilot followStarting valueDisabled What it controls and whyAutopilot following is off; the configured spring and load retain the hardware feel.
Autopilot follow authorityStarting value0.05 What it controls and whySets admitted AP-follow gain, not a percentage of travel. Runtime ownership and input limits still apply.
Autopilot neutral holdStarting valueDisabled What it controls and whyPermits centering hold during a supported AP state, separate from following a moving target.
Autopilot neutral hold strengthStarting value0.6 What it controls and whySets admitted AP neutral-hold strength; inactive while neutral hold is disabled.
EnabledStarting valueEnabled What it controls and whyEnables aerodynamic cues; each still needs nonzero strength and its simulator conditions.
GainStarting value0 What it controls and whySets stall-buffet strength. Zero removes the cue without changing simulator stalls or warnings.
GainStarting value0 What it controls and whySets high-Mach buffet strength; onset and full-strength thresholds are separate.
GainStarting value0 What it controls and whySets flap buffet at the configured position and speed gates. Flap movement texture is separate.
Maximum flap indexStarting value1 What it controls and whySets the final flap index for detent normalization. UP plus three detents uses maximum index3.
Minimum flap indexStarting value1 What it controls and whySets the first flap detent that admits buffet; this is a handle index, not degrees.
GainStarting value0 What it controls and whySets gear aerodynamic buffet; movement and ground-contact cues are separate.
Shaker EnabledStarting valueDisabled What it controls and whyPermits shaker at supported warning conditions; the switch does not establish aircraft equipment.
Stick shaker amplitudeStarting value0.5 What it controls and whySets triggered shaker strength; inactive while the shaker feature is disabled.
EnabledStarting valueEnabled What it controls and whyEnables ground effects; each still needs its own strength and contact or motion telemetry.
GainStarting value0 What it controls and whySets rolling texture strength, modified by speed, surface and undercarriage configuration.
GainStarting value0 What it controls and whySets gear-bump texture during ground motion, separate from touchdown impact.
GainStarting value0.5 What it controls and whySets landing-impact strength; landing telemetry and response shape determine the pulse.
GainStarting value0 What it controls and whySets reverse-thrust vibration with valid reverser and engine conditions. Zero removes the cue.
EnabledStarting valueEnabled What it controls and whyEnables engine cues with nonzero settings and valid running-engine telemetry.
GainStarting value0.06 What it controls and whySets estimated engine vibration using configured telemetry and response, not measured cockpit vibration.
EnabledStarting valueEnabled What it controls and whyEnables accessory cues with configured strengths and observed accessory movement.
GainStarting value0 What it controls and whySets texture from observed flap movement; a command without movement does not establish the cue.
GainStarting value0 What it controls and whySets texture from observed gear movement, separate from aerodynamic and touchdown effects.
Limits and open questions
  • The CowanSim 206L3 manual distinguishes collective control, engine throttle and governor behavior.
  • For Bell 206B3 JetRanger, the cited feature is inherited from the explicitly scoped family/implementation evidence; this variant was not separately established by that source.
  • Cyclic longitudinal/lateral axis assignments are described; the source does not quantify mechanical cockpit loads.
  • Engine-RPM beep trim is engine control, not proof of cyclic pitch trim or magnetic force-trim anchoring.
  • The cited manual sections do not identify a 206 autopilot or externally usable servo-following contract.
  • Governor/throttle and hydraulic-switch behavior are documented; the switch's reported event limitation is add-on-specific.
  • Control bindings and engine trim do not derive the selected indicated-speed force reference.
  • The manual reports that the generic hydraulic-switch event does not work despite the cockpit switch; this limitation must be retained for this version.
  • Bindings and hydraulic controls do not calibrate cyclic force or rotor vibration; the unrelated noise-study citation cannot fill that gap.

Physical validation
