History & design
A medical programme changes aircraft as its needs grow
Helinet’s Children’s Hospital Los Angeles programme progressed from an early A109 to S-76 variants with more cabin space. Robinson’s 2019 report describes an S-76B and C+ serving patient transfers, supported by dedicated pilots, medical crews and maintenance staff.

The flight decision is separated from the patient’s condition
The report explains that Helinet pilots were not told a patient’s age or condition when considering a flight request. That programme policy aimed to keep emotional pressure out of the weather and flight-planning decision.

Pilot accounts
An offshore pilot adjusts to the D model
After years flying the S-76, Reid encountered a noticeably different workplace in the D model. He described a quieter cabin and reduced vibration, along with fuel consumption that mattered to the payload available on familiar offshore routes. These were practical comparisons within an operator that had used several generations of the family.
The Thales cockpit required a change from earlier S-76 panels, but Reid welcomed the way information could be selected and controlled. He also valued the accuracy of the flight-control system in everyday flying. His enthusiasm sits within the specific environment of National Helicopter Services: hot, humid conditions and journeys to offshore installations. The interview presents his operating experience, without treating his positive assessment as a guarantee for every load or departure.

Naktenis recalled passengers waiting in a running S-76 while approaching weather made the departure increasingly uncomfortable. She repeatedly questioned the decision to leave, but the captain continued after speaking with management. As visibility deteriorated further along the short route to JFK, her requests to turn back went unheeded.
They landed, and the passengers continued to their connections. Naktenis’s response was to resign and arrange a car home, leaving the helicopter without its required copilot. In retrospect she wished she had refused to remain aboard before departure. Her account describes the pressure she experienced and the boundary she eventually drew. It is an attributed recollection of one flight, rather than an investigation identifying an operator or a general judgement about the S-76.

Ward accompanied journalist Eric Adams during a demonstration of Sikorsky’s experimental Matrix system. He handled the start and taxi, then supervised as Adams used a tablet and alternative controls in flight. Ward also demonstrated the transition between conventional pilot inputs and the computer-managed flight, a central part of what the visit was intended to show.
In the interview, Ward described the resistance that such technology could initially provoke among experienced pilots. He wanted the system to leave crews more attention for their missions, and reported that pilots who tried it often changed their minds. This account combines his explanation with Adams’s observations during the flight. It concerns an experimental aircraft filled with test equipment, and does not imply that ordinary S-76s or their simulator models provide those capabilities.

The simulator model and controls
The S-76 was Sikorsky's first helicopter developed for the civil market. Twin turbines, a four-bladed main rotor and retractable gear supported passenger, offshore and emergency-service roles.
This profile selects CowanSim S-76C for MSFS 2020, MSFS 2024.
How this profile feels
The spring and damping approximate a supported cyclic around those AFCS functions. The spring stays independent of airspeed. Directed aerodynamic loading is omitted. Cyclic damping adds resistance to hardware motion.
Mode-dependent beep trim is broader than a local spring-centre latch. Local force trim is off. Autopilot following is off.
Controls and trim
The S76 documentation separates SAS, attitude retention, four-axis automatic flight and the flight director. Beep-trim meaning changes in IAS and vertical-speed modes; rotor-trim reset is a separate command.
The selected implementation
CowanSim’s software trim release/reset depends on centered or non-centering controllers and the selected SAS strategy in that aircraft’s edition.
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.

Simulator integration
InheritedThe profile targets msfs2020, msfs2024. Add-on-specific controls use only the supported references configured by this profile.
Force-feedback settings
InheritedThe settings define the profile’s effect balance. Device output limits affect physical hand force.
Starting settings and their rationale
These configured values are starting estimates. The explanations describe what each setting controls; physical validation appears separately below.
| Setting | Starting value | What it controls and why |
|---|---|---|
| Spring strength | Starting value0.16 | What it controls and whyThe spring and damping approximate a supported cyclic around those AFCS functions. The baseline spring is 0.16. Low-speed spring blending is off. |
| Master force gain | Starting value0.65 | What it controls and whyScales overall profile strength while preserving effect balance, subject to device and output limits. |
| Profile force gain | Starting value0 | What it controls and whyThe 0 gain omits sustained directed airspeed loading. Spring resistance remains independent. |
| Force tuning speed/reference | Starting value135 kt | What 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 speed | Starting value65 kt | What it controls and whySets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it. |
| Aileron force scale | Starting value0.72 | What it controls and whyRoll and pitch aerodynamic scales are 0.72 and 1, respectively. These stored weights do not create directed aerodynamic loading while that term is inactive. No custom spring-travel curve is enabled. |
| Elevator force scale | Starting value1 | What it controls and whyScales pitch aerodynamic loading; pitch spring travel and trim responses are separate settings. |
| Trim feel | Starting valueDisabled | What it controls and whyRetained for compatibility and group membership. Trim relief, rather than this flag, controls centre movement. |
| Trim relief | Starting valueDisabled | What it controls and whyAllows trim relief with supported control law and valid telemetry. Axis authorities set its amount. |
| Autopilot follow | Starting valueDisabled | What it controls and whyAutopilot following is off; the configured spring and load retain the hardware feel. |
| Autopilot neutral hold | Starting valueDisabled | What it controls and whyPermits centering hold during a supported AP state, separate from following a moving target. |
| Output force limit | Starting value0.55 | What it controls and whyCaps directed-force output. Native spring effects and device limits remain separate. |
All 44 starting settings and their rationale
The settings define the profile’s effect balance. Device output limits affect physical hand force.
| Setting | Starting value | What it controls and why |
|---|---|---|
| Spring strength | Starting value0.16 | What it controls and whyThe spring and damping approximate a supported cyclic around those AFCS functions. The baseline spring is 0.16. Low-speed spring blending is off. |
| Spring deadband | Starting value0.02 | What it controls and whySets travel around the centre before the baseline spring resists. Smaller values engage it sooner. |
| Profile force gain | Starting value0 | What it controls and whyThe 0 gain omits sustained directed airspeed loading. Spring resistance remains independent. |
| Master force gain | Starting value0.65 | What it controls and whyScales overall profile strength while preserving effect balance, subject to device and output limits. |
| QBlend Enabled | Starting valueDisabled | What it controls and whyAllows baseline spring strength to rise with indicated airspeed where the control law permits it. |
| QSpring Minimum Factor | Starting 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 Knots | Starting value8 kt | What 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 speed | Starting value65 kt | What it controls and whySets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it. |
| Force tuning speed/reference | Starting value135 kt | What 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 gain | Starting value0 | What it controls and whyAdds permitted spring resistance above the full-blend speed. Zero removes this high-speed increase. |
| Airspeed spring stiffening limit | Starting 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 scale | Starting value0.72 | What it controls and whyRoll and pitch aerodynamic scales are 0.72 and 1, respectively. These stored weights do not create directed aerodynamic loading while that term is inactive. No custom spring-travel curve is enabled. |
| Elevator force scale | Starting value1 | What it controls and whyScales pitch aerodynamic loading; pitch spring travel and trim responses are separate settings. |
| Output force limit | Starting value0.55 | What it controls and whyCaps directed-force output. Native spring effects and device limits remain separate. |
| Trim feel | Starting valueDisabled | What it controls and whyRetained for compatibility and group membership. Trim relief, rather than this flag, controls centre movement. |
| Trim relief | Starting valueDisabled | What it controls and whyAllows trim relief with supported control law and valid telemetry. Axis authorities set its amount. |
| Elevator Authority | Starting value0 | What it controls and whyScales supported pitch-trim relief and permitted centre movement. Zero removes pitch response. |
| Aileron Authority | Starting value0 | What it controls and whyScales supported roll-trim relief and permitted centre movement. Zero removes roll response. |
| Force Trim Enabled | Starting valueDisabled | What it controls and whyMode-dependent beep trim is broader than a local spring-centre latch. Local force trim is off. The stored latch parameters are inactive; the profile does not supply a local hold-where-left neutral. |
| GLoad Enabled | Starting valueDisabled | What it controls and whyAllows load-factor changes to modify permitted spring laws. Passive fly-by-wire feel can suppress it. |
| Rate Damping Enabled | Starting valueDisabled | What it controls and whyEnables rate damping with the configured coefficients and control law. |
| Autopilot follow | Starting valueDisabled | What it controls and whyAutopilot following is off; the configured spring and load retain the hardware feel. |
| Autopilot follow authority | Starting 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 hold | Starting valueDisabled | What it controls and whyPermits centering hold during a supported AP state, separate from following a moving target. |
| Autopilot neutral hold strength | Starting value0.6 | What it controls and whySets admitted AP neutral-hold strength; inactive while neutral hold is disabled. |
| Enabled | Starting valueEnabled | What it controls and whyEnables aerodynamic cues; each still needs nonzero strength and its simulator conditions. |
| Gain | Starting value0 | What it controls and whySets stall-buffet strength. Zero removes the cue without changing simulator stalls or warnings. |
| Gain | Starting value0 | What it controls and whySets high-Mach buffet strength; onset and full-strength thresholds are separate. |
| Gain | Starting value0 | What it controls and whySets flap buffet at the configured position and speed gates. Flap movement texture is separate. |
| Maximum flap index | Starting value1 | What it controls and whySets the final flap index for detent normalization. UP plus three detents uses maximum index3. |
| Minimum flap index | Starting value1 | What it controls and whySets the first flap detent that admits buffet; this is a handle index, not degrees. |
| Gain | Starting value0 | What it controls and whySets gear aerodynamic buffet; movement and ground-contact cues are separate. |
| Shaker Enabled | Starting valueDisabled | What it controls and whyPermits shaker at supported warning conditions; the switch does not establish aircraft equipment. |
| Stick shaker amplitude | Starting value0.5 | What it controls and whySets triggered shaker strength; inactive while the shaker feature is disabled. |
| Enabled | Starting valueEnabled | What it controls and whyEnables ground effects; each still needs its own strength and contact or motion telemetry. |
| Gain | Starting value0.15 | What it controls and whySets rolling texture strength, modified by speed, surface and undercarriage configuration. |
| Gain | Starting value0 | What it controls and whySets gear-bump texture during ground motion, separate from touchdown impact. |
| Gain | Starting value0.5 | What it controls and whySets landing-impact strength; landing telemetry and response shape determine the pulse. |
| Gain | Starting value0 | What it controls and whySets reverse-thrust vibration with valid reverser and engine conditions. Zero removes the cue. |
| Enabled | Starting valueEnabled | What it controls and whyEnables engine cues with nonzero settings and valid running-engine telemetry. |
| Gain | Starting value0 | What it controls and whySets estimated engine vibration using configured telemetry and response, not measured cockpit vibration. |
| Enabled | Starting valueEnabled | What it controls and whyEnables accessory cues with configured strengths and observed accessory movement. |
| Gain | Starting value0 | What it controls and whySets texture from observed flap movement; a command without movement does not establish the cue. |
| Gain | Starting value0.025 | What it controls and whySets texture from observed gear movement, separate from aerodynamic and touchdown effects. |
Limits and open questions
- CowanSim S-76C; msfs2020, msfs2024. Previously observed titles and implementation identifiers are retained; installed matching remains deferred.
- Powered rotorcraft cyclic with estimated support. No direct fixed-wing IAS loading or substitution of body attitude for cyclic position.
- AFCS owns trim references; pitch beep can alter airspeed rather than cyclic neutral. Bridge local FTR and fixed-wing relief are off until those semantics are separated.
- SAS is hands-on damping, ATT is retention, and coupled AP can use collective. AP/FD selection and servo targets remain distinct. AP servo-follow and neutral hold remain disabled; engagement indicators are not force-demand signals.
- S76C++ twin turbine, four-blade rotor and retractable wheels. Original product uses MSFS2020 architecture with documented2024 compatibility, not a claim of a separate native rebuild.
- 135 KIAS is an estimated feel reference, not cruise TAS or a certified limit. No invented Mach, VNE or weight scheduling.
- Read-only native telemetry for aircraft motion and accessory positions. Custom switches, display animations and mode lamps are not calibrated servo targets. No unverified LVars/datarefs or simulator writes.
- Spring 0.16; lateral scale 0.72; trim authorities 0/0; per-axis output cap .55. Editable engineering estimates, not measured hand forces. No body-rate torque, surface following or fabricated hydraulic-failure loads.
- New physical and installed-product checks deferred by owner. Existing separately recorded acceptance retains its original device, simulator, add-on and version limits. Source review does not broaden custom telemetry acceptance.
- Only actual accessory position changes drive movement texture; static drag and command-triggered kicks are disabled. Select and save an aircraft default when telemetry lacks a discriminating developer/configuration identity.
Physical validation
No physical force validation is recorded in this public catalogue for this revision. Documentary review and software checks do not establish how a particular device feels.
