Development milestones
First flight: June 12, 1994 ( 1994-06-12 )
The 777 entered service in 1995 after development with input from major airline customers. Its broad cabin and two very large engines filled a space between the 767 and 747. The programme expanded through different fuselage lengths, range developments and engine choices.
The 777-200ER offers several engine options, while the 777-300ER has its own airframe and equipment. PMDG and FlightFactor provide separate systems documentation for their simulated versions.

Among Clark’s favourite flying memories is base training in a 777: taking a large airliner to a quieter airport and practising circuits and touch-and-go landings. The aircraft happened to be the first 777 built, a former Boeing test machine, which added a sense of history to the experience. For a pilot whose enthusiasm had been confirmed by an Air Cadets flight as a teenager, it was a particularly satisfying milestone.
In airline service, Heathrow retained a personal attraction because of childhood family journeys through the airport. He describes enjoying the view over London while reminding himself to concentrate on the touchdown. He also explains why the autopilot does not remove the crew’s work: it gives pilots capacity to consider weather, suitable diversion airports, approaches and the services available on the ground. The interview combines the pleasure of flying with the continuing responsibility of managing the journey.
Nearly two decades after leaving the 777 fleet, Captain Lim attended a reunion with about sixty former colleagues in Kuala Lumpur. Some were pilots he had taught on the F27 in the 1980s who had gone on to command long-haul aircraft. Meeting them brought back the shared decisions and disruptions that had shaped their working lives, as well as the humour of simulator trips and time away from home.
He recalls a weather diversion from Perth to Adelaide, a pressurisation problem after leaving Stockholm and a decision to remain on the ground as a typhoon approached. The reunion also gave him a chance to settle a misunderstanding with a colleague after twenty years. His account is a personal memory of the people around the aircraft; the remembered distances, fuel quantities and operational circumstances have not been adopted as technical specifications.
Looking back three decades after the first 777 flight from Paine Field, Cashman remembered the responsibility of representing everyone who had prepared the aircraft. Engineers, customers, manufacturing staff and maintenance personnel had already completed their part of the work. At the moment of flight, he wanted to be sure that he fulfilled his own part just as well.
The aircraft left a lasting impression on him. Boeing’s written interview highlights describe his enjoyment of flying it and the pride he still felt in the programme thirty years later. His recollection gives the first-flight milestone a human setting: the person at the controls was conscious of a much larger team whose effort made that departure possible.

This profile selects FlightFactor 777-200ER v2 for X-Plane 12.
Spring resistance builds with the selected airspeed response. Directed aerodynamic loading is omitted.
Pitch-trim relief is off. Autopilot following is enabled for supported control references.
The 777 combines fly-by-wire with a conventional yoke, unlike the passive Airbus sidestick. PMDG describes C-star-U laws and artificial feel, with normal/direct behavior and custom trim logic. ER, LR, 300ER and freighter configurations retain different engines and product identities. FlightFactor's v2 X-Plane family is separately scoped from its older 777 package and from PMDG's implementation.
FlightFactor's XP12 v2 family separates 200ER/200LR/300ER/777F expansions. Shared identity does not establish installed acceptance of every expansion or the older 777 generation.
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.
施加於模型產出的一切、在裝置上限之前的最終整體輸出縮放。
調高: 一切(彈簧、載荷、效果)一同增強。
調低: 一切一同變柔。
設定理由: Scales overall profile strength while preserving effect balance, subject to device and output limits.
把搖桿拉回中央的基礎回中力。其他所有力都疊加在它之上。太低,正常飛行中搖桿會發軟;太高,它會與你的手較勁,並掩蓋疊加其上的細微提示。
調高: 更硬的回中,更抗手。
調低: 更軟的桿,只靠氣動載荷。
設定理由: Artificial yoke feel motivates the configured powered-control response; the presence of fly-by-wire does not imply a passive Airbus-style inceptor. The baseline spring is 0.2. Low-speed spring blending is off.
777-200ER777-200LR777-300ER for MSFS 2020 & 2024777F for MSFS 2020 & 2024中央附近彈簧保持安靜的小中立區,讓靜止時的微小移動不會咔嗒作響。更寬更安穩但更松,更窄更精確但可能在中央附近抖動。
調高: 更安靜但更松的中央,曠量更大。
調低: 更緊的中央,靜止時可能抖動。
設定理由: Sets travel around the centre before the baseline spring resists. Smaller values engage it sooner.
設定理由: Adds smoothly ramped resistance outside the centre deadband. Zero removes this preload.
設定理由: Sets the travel used to ramp in centre preload. Wider intervals make its onset more gradual.
作用於兩條持續軸載荷的主縮放,在它們各自的獨立平衡之前施加。設定檔通常不動它,而是調校兩條軸載荷。
調高: 兩軸載荷一同加重。
調低: 兩軸一同減輕。
設定理由: The stored 0 aerodynamic-load gain is inactive under the zero hydraulic-load factor.
啟用低速彈簧介入視窗(上面的起始/全強度節數)。關閉時彈簧在所有速度下恆定。
設定理由: Allows baseline spring strength to rise with indicated airspeed where the control law permits it.
在靜止、空速尚未產生氣動力之前,彈簧還剩多少。下限高,停機時搖桿結實;下限低,則是停放輕型飛機那種鋼索鬆弛的感覺。
調高: 停機和滑行時桿更結實。
調低: 停機時桿發軟,只隨速度甦醒。
設定理由: Sets low-speed spring strength as a fraction of baseline when blending is enabled. One keeps full strength.
彈簧從低速下限開始向全強度攀升的空速:起飛滑跑中操縱面"甦醒"的那一刻。
設定理由: Sets the IAS where the low-speed spring blend starts rising. This is a feel threshold, not a flight limit.
彈簧達到全強度的空速。從起點到這裡,隨著氣流在操縱面上增強,回中逐漸變硬。
設定理由: Sets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it.
氣動載荷達到設計滿值的指示空速。它把整條載荷曲線錨定在飛機真實的速度範圍:172在110節就載滿,噴氣機要晚得多。
調高: 載荷來得更晚;桿輕到更高速度。
調低: 載荷來得更早,巡航更沉。
設定理由: Sets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit.
在偏轉載荷之外,回中本身隨速度變硬的程度。零則中央手感恆定;越大,巡航時回中越硬,起落航線上越松。
調高: 中央隨速度明顯變硬。
調低: 任何速度下中央手感恆定。
設定理由: The high-speed spring-stiffening gain is 1. It strengthens the permitted spring response above 122 KIAS, with the squared-speed ratio capped at 7.8.
速度驅動的中央變硬上限,防止高速飛行把彈簧無限上緊。
調高: 高速允許更多總硬化。
調低: 硬化更早封頂。
設定理由: Limits the squared airspeed ratio used for high-speed spring stiffening; it is not a device-force cap.
由副翼偏轉和空速產生的持續橫滾載荷,獨立於俯仰調校。與升降舵載荷一起,決定評測中常說的操縱協調比。
調高: 橫滾力更重。
調低: 副翼更輕更靈。
設定理由: Roll and pitch aerodynamic scales are 0.8 and 1, respectively. These stored weights do not create directed aerodynamic loading while that term is inactive. No custom spring-travel curve is enabled.
由升降舵偏轉和空速產生的持續俯仰載荷,獨立於橫滾調校。這是決定機型俯仰重量的主槓桿。它不影響副翼、彈簧、配平或抖振力。
調高: 速度下持續俯仰力更重。
調低: 升降舵更輕,握持更省力。
設定理由: Scales pitch aerodynamic loading; pitch spring travel and trim responses are separate settings.
每個穩態俯仰或橫滾力到達裝置前的上限,防止猛烈機動中砸擊或飽和硬體。
調高: 削波前更高的穩態力峰值。
調低: 更柔的上限;猛烈機動更早被抹平。
設定理由: Caps directed-force output. Native spring effects and device limits remain separate.
升降舵配平緩解持續俯仰力、移動桿的安定位置的強度。在100 %時,配平得當的飛機不需要保持壓力——正是真實飛行中"用配平消掉載荷"的流程。
調高: 配平消掉更多持續力;100 %時滿配平可完全抵消。
調低: 即使配平也仍要持續用力。
設定理由: Aircraft trim-rate and law behavior are documented, but a disabled profile trim response omits their hardware effect rather than reproducing them. Pitch relief is off, with stored authority 0; roll authority is 0.
777-200ER777-200LR777-300ER for MSFS 2020 & 2024777F for MSFS 2020 & 2024橫滾配平的同類緩解。多數通航機型沒有真正的副翼配平,所以保持為零;有橫滾配平的機型獲得相應的值。
調高: 橫滾配平消掉更多持續力。
調低: 橫滾配平作用更小。
設定理由: Scales supported roll-trim relief and permitted centre movement. Zero removes roll response.
由輪速和地面型別(鋪裝、草地、礫石)產生的滾動振動。
調高: 桿上更強的地面質感。
調低: 更平滑的滑行。
設定理由: Sets rolling texture strength, modified by speed, surface and undercarriage configuration.
來自伸縮縫、車轍和粗糙地面的短促離散顛簸,為持續隆隆聲打上標點。
調高: 接縫與車轍的衝擊更清晰。
調低: 更柔的地面細節。
設定理由: Sets gear-bump texture during ground motion, separate from touchdown impact.
接近失速及失速警告響起時的機體抖動:這副機翼宣告不滿的音量。斷失乾脆的機型抖振收斂,讓喇叭承擔警告。
調高: 更強的失速前顫抖。
調低: 更含蓄的機翼;警告交給喇叭。
設定理由: Sets stall-buffet strength. Zero removes the cue without changing simulator stalls or warnings.
接近馬赫極限的跨音速抖振。對接近MMO的噴氣機有意義,對到不了那裡的活塞機和渦槳機為零。
調高: 接近馬赫極限時更強的跨音速抖振。
調低: 高馬赫下更平滑的飛行。
設定理由: Sets high-Mach buffet strength; onset and full-strength thresholds are separate.
襟翼伸入氣流後機體的低頻振動,發生在它們真正做功的速度視窗內。
調高: 襟翼做功時更粗糙的飛行。
調低: 更柔的進近襟翼。
設定理由: Sets flap buffet at the configured position and speed gates. Flap movement texture is separate.
可收放起落架懸在氣流中引起的機體鼓振。固定起落架機型為零,它們的機體外形從不改變。
調高: 放起落架時更多鼓振。
調低: 放起落架飛行更乾淨。
設定理由: Sets gear aerodynamic buffet; movement and ground-contact cues are separate.
由飛機自身失速警告系統觸發的專用抖桿器振動。只有真有抖桿器的機型才有值;其餘全靠氣動抖振和喇叭。
調高: 更硬的抖桿器。
調低: 更含蓄的抖桿器。
設定理由: Sets triggered shaker strength; inactive while the shaker feature is disabled.
機輪觸及跑道那一下的單次衝擊,按下沉率縮放:輕柔著陸是耳語,結實到達是一記悶響。
調高: 觸地時更硬的一擊。
調低: 更柔的到達。
設定理由: Sets landing-impact strength; landing telemetry and response shape determine the pulse.
反推或槳葉beta區工作時的滑跑振動。無反推機型為零。
調高: 反推下更粗糙的滑跑。
調低: 更含蓄的反推。
設定理由: Sets reverse-thrust vibration with valid reverser and engine conditions. Zero removes the cue.
從慢車到全功率跟隨轉速的持續動力裝置振動——前方有東西在燒油的永恆提醒。
調高: 桿裡更多引擎。
調低: 更含蓄的引擎。
設定理由: Sets estimated engine vibration using configured telemetry and response, not measured cockpit vibration.
僅在模擬器報告襟翼舵面確實移動時的持續振動。它跟隨真實作動器的運動和故障,而非估算的計時器。
調高: 襟翼移動中更多振動。
調低: 更含蓄的襟翼行程。
設定理由: Sets texture from observed flap movement; a command without movement does not establish the cue.
自動駕駛指令可以讓桿實際移動多遠。在MSFS中保持極小,因為移動的軸可能被讀回為飛行員輸入;零則完全停用跟隨。
調高: 自動駕駛讓你的桿移動得明顯更多。
調低: 幾乎察覺不到的跟隨。
設定理由: Sets admitted AP-follow gain, not a percentage of travel. Runtime ownership and input limits still apply.
Whether this feature is active in this profile.
設定理由: Retained for compatibility and group membership. Trim relief, rather than this flag, controls centre movement.
Whether this feature is active in this profile.
設定理由: Allows trim relief with supported control law and valid telemetry. Axis authorities set its amount.
Whether this feature is active in this profile.
設定理由: Enables local force trim, separate from aircraft-owned trim and add-on integration qualification.
Whether this feature is active in this profile.

設定理由: Enables rate damping with the configured coefficients and control law.
Whether this feature is active in this profile.
設定理由: Following is on at 1 authority when a supported, valid autopilot control reference is available.

設定理由: Permits centering hold during a supported AP state, separate from following a moving target.
設定理由: Sets admitted AP neutral-hold strength; inactive while neutral hold is disabled.
Whether this feature is active in this profile.
設定理由: Enables aerodynamic cues; each still needs nonzero strength and its simulator conditions.
Where this effect reaches full strength (or has fully faded, for washouts).
調高: a more gradual build to a later peak.
調低: a quicker build.
設定理由: Sets the final flap index for detent normalization. UP plus three detents uses maximum index3.
Where this effect begins fading in.
調高: the effect begins later.
調低: it begins earlier.
設定理由: Sets the first flap detent that admits buffet; this is a handle index, not degrees.
Whether this feature is active in this profile.
設定理由: Permits shaker at supported warning conditions; the switch does not establish aircraft equipment.
