A few places to begin, from the aircraft’s story to the people who fly it.
Meet the aircraft
Boom's XB-1 is an experimental demonstrator for the Overture programme. Its slender fuselage and highly swept wing are paired with three General Electric J85 engines. The demonstrator first flew in March 2024 and reached supersonic flight during its 2025 test programme. Its value in a simulator is the chance to examine a specialised experimental cockpit and an unusual flight envelope.

History & design
The supersonic flight feels smooth from the cockpit
Speaking to CNN after the 28 January 2025 flight, Brandenburg described the XB-1 as smooth at supersonic speed. He explained that the Mach indication, rather than hearing a sonic boom inside the cockpit, marked the change for him.

The first flight requires a sceptic to become ready to go
Shoemaker described a change in outlook as XB-1 approached its first flight. During development, he had to question assumptions and encourage the team to imagine how the aircraft might behave. Lined up on the runway, he needed confidence that those concerns had been addressed and that the people supporting him were ready.
That confidence still allowed for surprises. He expected the real aircraft to reveal things that hundreds of simulator hours could not, and felt a strong responsibility not to let his own flying undermine the team’s preparation. The first outing deliberately kept its ambitions limited, including leaving the landing gear extended. His recollection centres on that balance between trust in the work already done and attentiveness to an unfamiliar aircraft.

Brandenburg could see his own nerves when he watched the cockpit recording of his first XB-1 flight. His breathing changed just before brake release, but the apprehension faded once the wheels left the ground. Time in the simulator had made the transition to the real aircraft feel unexpectedly familiar.
Preparing each briefing was another way of building confidence. Writing down the plan and explaining it to colleagues forced him to think through the flight. He also described the value of a consistent routine and a prayer at the foot of the ladder, acknowledging the people and opportunities that had brought him there. He still felt nervous before test flights, but regarded that awareness as part of taking the work seriously.

The simulator model and controls
Boom's XB-1 is an experimental aircraft, not a passenger-carrying version of Overture. Its slender fuselage and highly swept wing are paired with three General Electric J85 engines. The demonstrator first flew in March 2024 and reached supersonic flight during its 2025 test programme.
This profile selects FlightFX Boom XB-1 for MSFS 2024.
How this profile feels
The spring stays independent of airspeed. Directed aerodynamic loading is omitted.
Pitch-trim relief is off. Autopilot following is off.
Controls and trim
The XB-1 guide explicitly describes mechanically commanded hydraulic primary controls, with no fly-by-wire or autopilot. Hydraulic actuators isolate surface airloads; programmed pitch Q-feel supplies resistance using Mach and altitude. Roll-ratio adjustment changes response displacement rather than force. The aircraft has no flaps, slats or spoilers. Its custom trim, damper and feel assignments therefore cannot be inferred from an ordinary airliner configuration.
The selected implementation
FlightFX, Working Title and Boom collaborated on native MSFS 2024 XB-1. Achieved Mach 1.18 and its described Mach 1.4 envelope are different facts, neither an IAS force threshold.
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.

The aircraft has no flaps, slats or spoilers. Its custom trim, damper and feel assignments therefore cannot be inferred from an ordinary airliner configuration.
Trim
InheritedCustom pitch trim is documented, but the profile's permitted centre response remains a simplified feel representation rather than a verified generic trim interface. Pitch relief is off, with stored authority 0; roll authority is 0.
Autopilot and stability
InheritedAutopilot following is off; the configured spring and load retain the hardware feel.

Speeds and limits
InheritedThe indicated-speed references set the profile response scale; they are separate from aircraft operating limits.
Simulator integration
InheritedThe profile targets 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 value0.8 | What it controls and whyThe powered-control spring approximates artificial pitch feel; the actual Mach/altitude Q-feel schedule and roll-ratio mechanism are not reproduced by one IAS reference. The baseline spring is 0.8. Low-speed spring blending is off. |
| 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 | What it controls and whyThe stored 0 aerodynamic-load gain is inactive under the zero hydraulic-load factor. |
| Force tuning speed/reference | Starting value250 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 value70 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 value0.65 | What it controls and whyRoll and pitch aerodynamic scales are 0.65 and 0.86, 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 value0.86 | 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 value0.8 | What it controls and whyThe powered-control spring approximates artificial pitch feel; the actual Mach/altitude Q-feel schedule and roll-ratio mechanism are not reproduced by one IAS reference. The baseline spring is 0.8. Low-speed spring blending is off. |
| Spring deadband | Starting value0.04 | 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 stored 0 aerodynamic-load gain is inactive under the zero hydraulic-load factor. |
| Master force gain | Starting value0.85 | 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 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 value20 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 value70 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 value250 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 whyThe high-speed spring-stiffening gain is 0. No additional speed-driven stiffening is added; this does not disable independent aerodynamic loading. |
| 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 value0.65 | What it controls and whyRoll and pitch aerodynamic scales are 0.65 and 0.86, 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 value0.86 | 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 whyCustom pitch trim is documented, but the profile's permitted centre response remains a simplified feel representation rather than a verified generic trim interface. Pitch relief is off, with stored authority 0; roll authority is 0. |
| 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 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. |
| 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 value0.1 | 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 value0.9 | 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 value0.4 | What it controls and whySets rolling texture strength, modified by speed, surface and undercarriage configuration. |
| Gain | Starting value0.32 | What it controls and whySets gear-bump texture during ground motion, separate from touchdown impact. |
| Gain | Starting value0.9 | 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 value0.06 | 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 value0.12 | What it controls and whySets texture from observed gear movement, separate from aerodynamic and touchdown effects. |
Limits and open questions
- Force amplitudes, gradients, damping and cue onset are editable engineering estimates, not measured hand forces. Documentary and synthetic review do not establish installed or physical acceptance.
- No autopilot follow/hold, local force-trim release, surface-follow, hydraulic-failure load or simulator-axis injection. A cockpit switch or flight-director bar is not a calibrated inceptor demand.
- Actual flap and landing-gear position changes drive accessory textures. Commands, indicators, custom audio and visual vibration do not establish force telemetry.
- Documentary identities need a developer or distinctive package identifier. If the aircraft omits it, select the correct profile and save it as the aircraft default. No other developer is matched from ICAO alone.
- Powered controls with artificial pitch feel, not FBW. A restrained fixed nominal force approximates the selected setting; no invented Q-feel knob-to-force schedule or roll-ratio loading.
- Custom pitch/yaw trim and interrupted damper/trim states are not standard mechanical-neutral telemetry. Both trim paths off.
- No AP fitted; pseudoILS FD work does not supply AP follow or inceptor demand.
- 250KIAS nominal tuning choice. No Mach-to-KIAS substitution, fixed stall speed or generic VNE cue.
- Manual explicitly notes no stock assignments forQfeel/dampers/rollratio. Knob state and units remain unmapped. Nominal feel limitation is visible in profile evidence.
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.
