Aircraft and simulator scope
- Hawker 800XP · MSFS 2024 · Variant starting point
Universal named configuration; current availability scope: msfs2024. This is not installed-add-on or edition acceptance. · Selected source passages were inspected. Historical/family manual applicability is stated separately from current simulator availability.
The simulator model and controls
A business jet with manually linked primary controls, tab trim and separate stall-protection systems.
How this profile feels
Spring resistance builds with the selected airspeed response. A separate aerodynamic term adds speed-dependent control load.
Pitch-trim relief is off. Autopilot following is off.
Aircraft and configuration
The 800XP primary controls are cable-operated and balanced; the elevator circuit includes a spring and G-weight.
Pitch trim uses elevator tabs, and aileron trim uses a tab on the left aileron. Electric, autopilot and Mach pitch trim share a servomotor.
Primary controls and the pitch servomotor
The v1.1 manual describes cable-operated primary controls, balancing and elevator spring/G-weight arrangements. Electric trim, autopilot trim and Mach trim use the pitch servomotor. Hydraulics operate accessories and the pusher; the primary controls remain manually linked.
Flaps and ground lift dump
Normal flap gates are 0, 15, 25 and 45 degrees. The 75-degree lift-dump position is ground-only and is commanded through the airbrake baulk. Shaker and pusher systems have distinct channels and interlock conditions.
About the values
Strengths are normalized hardware-feel settings. They set the effect balance; hand force depends on the device and its limits. The IAS reference is a tuning value.
What the documentation establishes
The 800XP primary controls are cable-operated and balanced; the elevator circuit includes a spring and G-weight.
Pitch trim uses elevator tabs, and aileron trim uses a tab on the left aileron. Electric, autopilot and Mach pitch trim share a servomotor.

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 value0.72 | What it controls and whyPrimary controls: Manual cable runs. The baseline spring is 0.72. Its low-speed blend reaches baseline strength at 105 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 value0.64 | What it controls and whyThe aerodynamic-load gain is 0.64 with an indicated-speed reference of 250 KIAS. This supplies speed-dependent loading alongside the spring. |
| 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 value105 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 value0.8 | What it controls and whyRoll and pitch aerodynamic scales are 0.8 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 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. |

| Setting | Starting value | What it controls and why |
|---|---|---|
| Spring deadband | Starting value0.045 | 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 value0.5 | What it controls and whySets low-speed spring strength as a fraction of baseline when blending is enabled. One keeps full strength. |

| Rate Damping Enabled | Starting valueEnabled | What it controls and whyEnables rate damping with the configured coefficients and control law. |
| 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 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 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 value3 | What it controls and whySets the final flap index for detent normalization. UP plus three detents uses maximum index3. |

| Enabled | Starting valueEnabled | What it controls and whyEnables accessory cues with configured strengths and observed accessory movement. |
| Gain | Starting value0.055 | What it controls and whySets texture from observed flap movement; a command without movement does not establish the cue. |
| Gain | Starting value0.055 | What it controls and whySets texture from observed gear movement, separate from aerodynamic and touchdown effects. |
Limits and open questions
- Hawker 800XP is a universal type/configuration starting point. The separately documented current product supplies availability scope; this does not assert installed matching or edition qualification.
- Trim-force mapping, autopilot follow/neutral hold, custom shaker/pusher and hydraulic-failure loads remain disabled until their exact signal and equipment contracts are qualified.
- Force and texture magnitudes are inherited editable estimates. Owner physical and installed-aircraft acceptance remain pending.
- Mach-trim servo state, lift-dump baulk and shaker/pusher interlocks have no qualified generic force interface. Optional developer immersion may already contribute aircraft motion.
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.
