Aérospatiale Alouette III

Free and ProRevision 1Partial review

Aérospatiale Alouette III: The cyclic's configured centre and damping provide a handling reference for the articulated-rotor helicopter; blade count does not determine cyclic hand force.

The simulator model and controls

Sud Aviation developed the Alouette III as a larger follow-on to the Alouette II. The design uses a single turbine, a three-bladed main rotor and wheeled landing gear. It served civilian and military operators in transport, rescue and many other roles.

This starting point selects Aérospatiale Alouette III. 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 is off. 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

Taog's SA316B manual describes an articulated three-blade main rotor and pedal-controlled tail-rotor pitch. The basic aircraft has three wheels; skis and floats are separate surface kits. An optional Astazou attachment is described, but the attachment alone does not show a different simulated engine or cyclic-loading system. Rotor and ground cues retain the selected equipment's scope.

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.

What the documentation establishes

The manual identifies the SA316B package and its fixed three-wheel undercarriage, with optional skis or floats.

The manual describes an articulated three-blade main rotor and pedal-controlled tail-rotor pitch.

Three-wheel gear, optional surface kits and the documented rotor arrangement provide equipment context, not force-cue amplitudes.

The manual gives cruise and sea-level never-exceed figures in km/h; the preset's indicated-knot reference remains a tuning choice.

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.

Starting settings and their rationale

These configured values are starting estimates. The explanations describe what each setting controls; physical validation appears separately below.

Estimated starting settings · revision 1
SettingStarting valueWhat it controls and why
Spring strengthStarting value0 What it controls and whyThe cyclic's configured centre and damping provide a handling reference for the articulated-rotor helicopter; blade count does not determine cyclic hand force. The baseline spring is 0. Its low-speed blend reaches baseline strength at 50 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 100 KIAS. This supplies speed-dependent loading alongside the spring.
Force tuning speed/referenceStarting value100.0 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 value50.0 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.
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.
Autopilot followStarting valueDisabled What it controls and whyAutopilot following is off; the configured spring and load retain the hardware feel.
Autopilot neutral holdStarting valueDisabled What it controls and whyPermits centering hold during a supported AP state, separate from following a moving target.
Output force limitStarting value0.55 What it controls and whyCaps directed-force output. Native spring effects and device limits remain separate.

Estimated starting settings · revision 1
SettingStarting valueWhat it controls and why
Spring strengthStarting value0 What it controls and whyThe cyclic's configured centre and damping provide a handling reference for the articulated-rotor helicopter; blade count does not determine cyclic hand force. The baseline spring is 0. Its low-speed blend reaches baseline strength at 50 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 100 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 value14.0 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 value50.0 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 value100.0 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 valueDisabled What it controls and whyLocal force trim represents a hardware spring-centre latch only when enabled; the surface kit does not establish a different trim mechanism. Local force trim is off. The stored latch parameters are inactive; the profile does not supply a local hold-where-left neutral.
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 value0.15 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
  • No cyclic trim-release mechanism or anchoring contract is established by the examined Alouette rotor description.
  • The examined Alouette manual sections do not identify an autopilot or servo-driven cyclic following.
  • Rotor construction does not establish rotor-frequency vibration amplitude or measured cyclic forces for the preset.
