The simulator model and controls
The TBM programme began as a collaboration between SOCATA and Mooney and continued under Daher. The low-wing airframe carries one nose-mounted turboprop and a pressurised cabin. Successive versions developed the engines, aerodynamics, avionics and pilot interface.
This profile selects Black Square TBM 850 for MSFS 2020, MSFS 2024.
How this profile feels
The powered-control profile provides its selected yoke centering. Spring resistance builds with the selected airspeed response. A separate aerodynamic term adds speed-dependent control load.
Trim changes aircraft balance; the selected profile determines the amount of hardware relief. Valid trim provides the configured pressure relief. Autopilot following is off.
Controls and trim
The selected TBM documentation distinguishes elevator anti-tabs from other trim tabs. Automatic-flight disengagement can leave flight-director modes displayed, so the flight director, autopilot and manual trim are separate cockpit states. TBM model and avionics generations remain named in the individual product.
The selected implementation
Black Square’s TBM 850 models elevator anti-tabs and separate trim tabs. Disconnecting the autopilot can leave flight-director modes selected.
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.

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 value0.74 | What it controls and whyThe powered-control profile provides its selected yoke centering. The baseline spring is 0.74. Its low-speed blend reaches baseline strength at 65 KIAS. |
| Master force gain | Starting value0.85 | What it controls and whyScales overall profile strength while preserving effect balance, subject to device and output limits. |
| Profile force gain | Starting value0.68 | What it controls and whyThe aerodynamic-load gain is 0.68 with an indicated-speed reference of 190 KIAS. This supplies speed-dependent loading alongside the spring. |
| Force tuning speed/reference | Starting value190 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. They set the aerodynamic axis balance. 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 valueEnabled | 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 value0.74 | What it controls and whyThe powered-control profile provides its selected yoke centering. The baseline spring is 0.74. Its low-speed blend reaches baseline strength at 65 KIAS. |
| Spring deadband | Starting value0.05 | What it controls and whySets travel around the centre before the baseline spring resists. Smaller values engage it sooner. |

| QBlend Enabled | Starting valueEnabled | What it controls and whyAllows baseline spring strength to rise with indicated airspeed where the control law permits it. |
| QSpring Minimum Factor | Starting value0.55 | 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 value190 kt | What it controls and whySets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit. |

| Force Trim Enabled | Starting valueDisabled | What it controls and whyEnables local force trim, separate from aircraft-owned trim and add-on integration qualification. |
| GLoad Enabled | Starting valueEnabled | What it controls and whyAllows load-factor changes to modify permitted spring laws. Passive fly-by-wire feel can suppress it. |

| 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. |

| 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 value2 | What it controls and whySets the final flap index for detent normalization. UP plus three detents uses maximum index3. |

| Gain | Starting value0.32 | What it controls and whySets gear-bump texture during ground motion, separate from touchdown impact. |
| Gain | Starting value0.82 | What it controls and whySets landing-impact strength; landing telemetry and response shape determine the pulse. |

Limits and open questions
- Black Square TBM 850; msfs2020, msfs2024. Previously observed titles and implementation identifiers are retained; installed matching remains deferred.
- Manual high-performance turboprop yoke approximation retained; electrical trim and hydraulic accessories do not prove boosted primary control.
- Pitch anti-tab and roll trim are distinguished. Estimated pitch/roll relief remains editable; the anti-tab note does not establish a calibrated linear neutral law or failure torque.
- FD mode selection can remain after AP master disconnect. No undocumented AP servo demands are read or written. AP servo-follow and neutral hold remain disabled; engagement indicators are not force-demand signals.
- TBM850 single turboprop, retractable gear and flaps. Power-selection, feather and beta behavior remain simulator-owned; no turbine vibration is synthesized from piston RPM.
- 190 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 0.74; lateral scale 0.72; trim authorities 0.3/0.14; per-axis output cap 0.55. 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
