Olga Ernst · CC BY-SA 4.0 · Airbus H125The H125 belongs to the AS350 lineage developed by Aérospatiale and continued through Eurocopter into Airbus Helicopters. Its broad cabin and single turbine support work ranging from passenger transport to observation and external-load operations.
The names reflect both the aircraft's history and its markets: Écureuil means squirrel, while AStar is familiar in North America. Equipment changed through the AS350 and H125 generations. Bundled simulator aircraft and independent add-ons have separate systems descriptions.
Airbus H125
The FAI records Delsalle’s 14 May 2005 takeoff from Everest in an AS350 B3. The achievement belongs to a specially prepared test mission in that earlier family variant, rather than establishing ordinary passenger or rescue capability at the summit.
Airbus’s 2018 operator interviews describe helicopters moving climbers and evacuating people affected by illness or injury in Nepal.
First flight: 27 June 1974
Dulal recalled a rescue that remained particularly vivid among his mountain flying. A climber at Lobuche had a broken leg and altitude sickness, while poor weather complicated reaching the glacier. Bringing the patient aboard took time, and the clouds continued to close around the landing area as the crew worked.
The departure required a difficult judgement between worsening conditions and the patient’s need for help. Dulal described the flight back through Lukla to Kathmandu as one of his most challenging missions. Dulal also expressed confidence in the H125.
Twenty years after Everest, Delsalle’s strongest memories included much more than handling the helicopter. Obtaining permission, arranging supplies and preparing a distant mission on a tight budget had been major obstacles. Engineers and technicians contributed extra time to the project, forming friendships that lasted long after the record flight.
In Nepal, the power of the mountain environment made an equally lasting impression. Delsalle described air movements unlike anything he had expected, reinforcing the respect for terrain he had learned during military training in the Alps. He gave substantial credit for the achievement to the people who designed and prepared the aircraft.
As a working mountain and rescue pilot, Bourke wanted to understand what the FastFin modification would change in familiar conditions. At Gunnison, the team loaded the test aircraft to resemble his usual missions. The cockpit carried additional instruments and recording equipment, giving the demonstration a different atmosphere from an ordinary working flight.
Bourke noticed smoother heading control during hovering and liked the response as they tried approaches. Dan Smith later demonstrated measured control margins while the displays showed pedal movement. Bourke had not witnessed the unmodified comparison flights, so his own assessment combined this demonstration with experience in other H125s. He came away enthusiastic about the modified aircraft, with his interest rooted in the precision and comfort required when carrying out difficult jobs in the mountains.

This profile selects CowanSim H125 / AS350B3e for MSFS 2020, MSFS 2024.
The spring stays independent of airspeed. Directed aerodynamic loading is omitted.
Local force trim is off. Autopilot following is off.
Cyclic damping is on. Its configured gain is 0.35; it resists hardware motion separately from the spring and aircraft stabilization.
The H125/AS350 has hydraulically assisted cyclic controls. The cited AS350 retrofit account describes very little aerodynamic feedback and quick linkage response; servo transparency under high loads is a separate documented phenomenon that this profile does not reproduce. CowanSim's optional HeliSAS distinguishes force-trim procedures for spring-centred and noncentering controls. Its trim-release and reset commands are not continuously readable hardware-neutral positions.
CowanSim's per-aircraft and simulator-edition trim/reset behavior remains separate from a local hardware-centre latch. An unsupported hydraulic binding does not create a force command.
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.
モデルが生み出すすべてに適用される最終的な全体出力スケール。デバイス上限の前に適用されます。
上げると: すべて(バネ、荷重、効果)が一緒に強まります。
下げると: すべてが一緒に和らぎます。
この値の理由: Scales overall profile strength while preserving effect balance, subject to device and output limits.
スティックを中央へ引き戻す基本のセンタリング力。他のすべての力はこの上に積み重なります。低すぎると通常飛行でスティックが頼りなく、高すぎると手に逆らい、上に重なる細かな手がかりを覆い隠します。
上げると: 手により強く抵抗する、固いセンタリング。
下げると: 空力荷重だけに頼る、柔らかいスティック。
この値の理由: Nominal cyclic centering represents the boosted control arrangement without adding an unmodeled servo-transparency force. The baseline spring is 0.14. Low-speed spring blending is off.
User ManualCowanSim HeloSAS autopilot manualUser ManualSAS ManualAS350 Garmin GFC 600H Flight Control SystemJack Be Nimble中央付近でバネが沈黙する小さなニュートラルゾーン。静止時の微小な動きがガタつかないようにします。広いほど落ち着きますが緩くなり、狭いほど精密ですが中央で震えることがあります。
上げると: より静かだが緩い、遊びの多い中央。
下げると: 静止時に震えうる、締まった中央。
この値の理由: Sets travel around the centre before the baseline spring resists. Smaller values engage it sooner.

上げると: 両軸がより強く荷重します。
下げると: 両軸が一緒に軽くなります。
この値の理由: The 0 gain omits sustained directed airspeed loading. Spring resistance remains independent.
低速のバネ立ち上げ窓(上記の開始/全強度ノット)を有効にします。オフではバネは全速度で一定です。
この値の理由: Allows baseline spring strength to rise with indicated airspeed where the control law permits it.
停止状態で、速度が空力を生む前にバネがどれだけ残るか。床が高いと駐機中のスティックはしっかりし、低いと駐機した軽飛行機のケーブルが緩んだような感触になります。
上げると: 駐機・タキシー時により固いスティック。
下げると: 速度でしか目覚めない、駐機時の柔らかいスティック。

この値の理由: Sets the IAS where the low-speed spring blend starts rising. This is a feel threshold, not a flight limit.
バネが全強度に達する速度。開始点からここまでの間、舵面上の気流が増すにつれセンタリングは徐々に固まります。
この値の理由: Sets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it.

上げると: 荷重の到来が遅くなり、より速くまでスティックが軽いまま。
下げると: 荷重が早く到来し、巡航がより重く。
この値の理由: Sets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit.

上げると: 速度とともに明確に固くなる中央。
下げると: どの速度でも一定の中央感覚。

上げると: より重いロール力。
下げると: より軽く機敏なエルロン。

エレベーター舵角と速度による持続的なピッチ荷重で、ロールとは独立に調整されます。機種ごとのピッチの重さを決める主レバーです。エルロン、バネ、トリム、バフェットの力には触れません。
上げると: 速度での持続ピッチ力がより重く。
下げると: 保持する力の軽い、より軽やかなエレベーター。
この値の理由: Scales pitch aerodynamic loading; pitch spring travel and trim responses are separate settings.
各定常ピッチ・ロール力がデバイスへ届く前の上限。強い機動でハードウェアを叩いたり飽和させたりしないための保護です。
上げると: クリップ前の定常力ピークがより高く。
下げると: より柔らかい天井。激しい機動が早く平らに。
この値の理由: Caps directed-force output. Native spring effects and device limits remain separate.
エレベータートリムが保持ピッチ力をどれだけ和らげ、スティックの落ち着き位置をずらすか。100 %では正しくトリムされた機体は保持圧が不要になり、実機の「荷重をトリムで消す」手順そのものです。
上げると: トリムがより多くの保持力を除去。100 %ではフルトリムで打ち消し。
下げると: トリムしても力を保持し続けます。
この値の理由: Scales supported pitch-trim relief and permitted centre movement. Zero removes pitch response.

上げると: ロールトリムがより多くの保持力を除去。
下げると: ロールトリムの効きが弱く。
この値の理由: Scales supported roll-trim relief and permitted centre movement. Zero removes roll response.

下げると: より柔らかな地面のディテール。
この値の理由: Sets gear-bump texture during ground motion, separate from touchdown impact.
失速接近時と失速警報作動中の機体の震え。この翼が不満をどれだけ大声で告げるかです。切れ味よく落ちる機種は控えめなバフェットになり、警報音に警告を任せます。
上げると: より強い失速前の震え。
下げると: より控えめな翼。警報音が警告を担います。
この値の理由: Sets stall-buffet strength. Zero removes the cue without changing simulator stalls or warnings.
マッハ限界接近時の遷音速バフェット。MMO付近のジェットには意味があり、そこへ到達しないレシプロやターボプロップではゼロです。
上げると: マッハ限界近くのより強い遷音速バフェット。

下げると: 脚下げ飛行がより綺麗に。
この値の理由: Sets gear aerodynamic buffet; movement and ground-contact cues are separate.

上げると: リバース中のより荒い滑走。
下げると: より控えめなリバース。

上げると: スティックのエンジンが増加。
下げると: より控えめなエンジン。
この値の理由: Sets estimated engine vibration using configured telemetry and response, not measured cockpit vibration.
シミュレーターがフラップ舵面の実際の移動を報告している間だけの連続振動。推定タイマーではなく、実際のアクチュエーター動作と故障に従います。
上げると: フラップ移動中の振動が増加。
下げると: より控えめなフラップ走行。
この値の理由: Sets texture from observed flap movement; a command without movement does not establish the cue.
オートパイロットの指令がスティックを物理的にどこまで動かせるか。動いた軸がパイロット入力として読み返されうるMSFSでは極小に保ちます。ゼロで追従は完全に無効です。
上げると: オートパイロットがスティックを目に見えて多く動かします。
下げると: ほぼ気づかない追従。
この値の理由: Sets admitted AP-follow gain, not a percentage of travel. Runtime ownership and input limits still apply.

この値の理由: Allows trim relief with supported control law and valid telemetry. Axis authorities set its amount.
