A few places to begin, from the aircraft’s story to the people who fly it.
Meet the aircraft
Beechcraft's King Air range grew from the 90-series aircraft into a broad family of pressurised utility and business transports. The later 200 and 300 series were originally marketed as Super King Airs. Their T-tails provide a quick visual distinction from the smaller 90-series lineage. The C90 and 350 aircraft gathered here differ in airframe, engines and systems. They also span conventional instrumentation and modern avionics.

Aarons reports an evaluation of N120SK during the Super King Air 350's late certification programme. One of the two evaluation pilots already knew the Model 300, making the comparison especially revealing: that pilot initially overcontrolled in pitch because the new aircraft required less effort. The crew subsequently liked the balance between pitch and roll forces, its climb attitude and the view from the cockpit.

Pilot accounts
The 350 feels lighter at the controls than the 300
Aarons reports an evaluation of N120SK during the Super King Air 350's late certification programme. One of the two evaluation pilots already knew the Model 300, making the comparison especially revealing: that pilot initially overcontrolled in pitch because the new aircraft required less effort. The crew subsequently liked the balance between pitch and roll forces, its climb attitude and the view from the cockpit. Across six takeoffs, they did not encounter power surging that needed manual correction.
The report also describes slow flight and asymmetric airwork. The crew found useful aileron response through the stall exercises and liked the aircraft's engine-out handling. Their observations of longitudinal and lateral stability are tied to the test loading and configuration described in the article. Reduced control effort was a prominent difference from the earlier model he knew.

Horne accompanied Peter Herr on a delivery flight carrying a new King Air 350 from the United States to its European customer. From the cockpit, the high seating position, broad wing and substantial feel made an immediate impression. The journey then supplied a more demanding test of the aircraft's usefulness: the Goose Bay–Reykjavik leg lasted nearly five hours, with headwinds reaching 75 knots near Greenland and the predicted fuel reserve becoming an uncomfortable focus of attention.
They arrived with more fuel than the most worrying prediction had suggested, but the destination provided another challenge. Strong, gusty wind at Reykjavik moved even this heavy aircraft around, requiring an appreciable crab on approach. Horne's account also stresses the value of familiarity with the flare and of having another pilot share the navigation-system work.

Read the full account · AOPA Pilot ↗A busy cockpit and a dependable working aircraft
McClellan writes from continuing experience in King Air 350 and 360 operations. He finds the cockpit demanding in small, physical ways: the pedestal makes getting into the seats awkward, propeller noise makes a good headset valuable, and changes in power or propeller speed call for attention to trim. The throttle response rewards careful, small movements. Once settled, however, he finds the seats comfortable, and passengers farther behind the propellers experience a quieter cabin.
His account also describes different crew preferences for operating the Pro Line Fusion avionics, which provide several ways to accomplish the same task. He favours cruising in the twenties rather than using the aircraft's highest available levels, partly for cabin comfort. Against those irritations, he sets his operation's dispatch experience: approximately 1,600 hours over four years with one cancellation attributed to a starter-generator. The combination helps explain his continued appreciation of an aircraft whose cockpit he describes without romanticising it.

The simulator model and controls
Beechcraft's King Air range grew from the 90-series aircraft into a broad family of pressurised utility and business transports. The later 200 and 300 series were originally marketed as Super King Airs. Their T-tails provide a quick visual distinction from the smaller 90-series lineage.
This profile selects Carenado C90 GTX King Air for X-Plane 11.
How this profile feels
Spring resistance builds with the selected airspeed response. A separate aerodynamic term adds speed-dependent control load.
Valid trim provides the configured pressure relief. Autopilot following is off.
Controls and trim
The King Air family spans C90, B200 and 350 airframes with different avionics and powerplants. The C90B manual documents mechanical elevator and aileron trim tabs, with rudder trim acting on yaw. A published 350 flight report describes heavier pitch than roll and effective trim wheels, supplying related-family handling context rather than a measured 350i force curve. The Black Square 350 and Airfoillabs 350 retain their own autopilot logic.
The selected implementation
Carenado C90 GTX XP11 lists Proline21 and a Flight Guidance Systems manual, separate from the C90B avionics.
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
Carenado identifies C90 GTX for XP11 with Proline21 and a Flight Guidance Systems manual.
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 whyPublished 350 handling supports a qualitative pitch-heavy balance; it does not fix a universal pitch/roll force ratio for every King Air. The baseline spring is 0.74. Its low-speed blend reaches baseline strength at 95 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 200 KIAS. This supplies speed-dependent loading alongside the spring. |
| Force tuning speed/reference | Starting value200.0 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 value95 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 value1.0 | What it controls and whyScales pitch aerodynamic loading; pitch spring travel and trim responses are separate settings. |
| Trim feel | Starting valueEnabled | 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. |

|---|---|---|
| Spring strength | Starting value0.74 | What it controls and whyPublished 350 handling supports a qualitative pitch-heavy balance; it does not fix a universal pitch/roll force ratio for every King Air. The baseline spring is 0.74. Its low-speed blend reaches baseline strength at 95 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. |

| 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. |
