Greg Goebel · CC BY-SA 2.0 · De Havilland Canada DHC-4 Caribou picturedThe Caribou first flew in 1958. It was built to move personnel and cargo using relatively short airfields, pairing a high wing with a large loading ramp and rugged landing gear. Military operators formed a major part of its service history.
It is larger and more specialised than the Beaver, yet belongs to the same Canadian utility-aircraft tradition. Two piston engines and a large cargo cabin supported transport work beyond the capacity of lighter bush aircraft.

The Caribou first flew in 1958, and early American deliveries went to the Army in 1961. Initially designated AC-1, it became CV-2 in 1962 and C-7 when transferred to the Air Force in January 1967. Its role centred on bringing troops, patients and supplies to short, unimproved strips.
Developed for military transport, the Caribou also found commercial work carrying cargo. De Havilland Canada describes access to remote locations as a defining part of its role. The accounts here show that work in different settings, from peacekeeping deployments to humanitarian transport and heritage flying.
First flight: 30 July 1958
Jaensch’s affection for the Caribou grew from how much of the flying remained in the crew’s hands. Without an autopilot or weather radar, getting from place to place kept them occupied. He found the overhead engine controls more comfortable than their position might suggest, and valued the view from the elevated seats. The flight engineer also brought essential loading and maintenance experience.
Slow approaches could demand large control movements, while the final landing and change into reverse required close coordination between pilots. Getting the touchdown right was especially satisfying. Humanitarian missions into Papua New Guinea were his strongest memories. Later, he captained the delivery of HARS’s first Caribou to Wollongong in 2011 and flew displays, extending his connection with the aircraft beyond its military service.
Returning to the Caribou with a heritage organisation brought Kelly back to his time supporting United Nations observers in Kashmir. He arrived expecting a handover, but illness among the other pilots put him straight into operational flying. On an early trip he landed beside waiting UN vehicles, only to have their occupants point out the intended airstrip elsewhere.
Other deliveries involved a stadium landing area shared with wandering cattle, makeshift runway lighting and routes through the Himalayas. His recollections retain the humour of those unusual assignments alongside the demands of operating a piston transport around high terrain. He credits the maintenance engineers who kept the aircraft available, drawing a connection with the volunteers whose work later allowed him to fly the Caribou again.
Mayer volunteered for United Nations flying while looking for a more adventurous posting. Conversion courses brought him to the Caribou and Otter before he left Canada for Egypt. The work included moving personnel and supplies, with poor weather information, limited navigation aids and uncertain conditions at remote landing areas complicating the crew’s day.
Caribou cargo could be surprising. He remembers arriving to find one aircraft packed with rabbit cages and boxes of rubber waders, making access to the cockpit difficult. Another episode showed how quickly the work depended on maintenance: corrosion at the wing-flap hinges grounded the Caribou fleet. A borrowed Dakota took over its tasks while the transports were unavailable. His account places the aircraft within the wider effort of keeping a remote operation supplied.

This profile selects X-Hangar DHC-4 Caribou for X-Plane 12.
The profile combines sustained transport resistance with separate radial-engine cues. Spring resistance builds with the selected airspeed response. A separate aerodynamic term adds speed-dependent control load.
Configured pitch relief is independent of the cargo-pod selection. Pitch-trim relief is off. Autopilot following is off.
X-Hangar’s Caribou is a twin-radial STOL transport with retractable gear and a cargo ramp. Its optional belly pod changes the cargo configuration. The cargo arrangement and engine type describe the transport around its flight controls.

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.
施加于模型产出的一切、在设备上限之前的最终整体输出缩放。
调高: 一切(弹簧、载荷、效果)一同增强。
调低: 一切一同变柔。
设定理由: Scales overall profile strength while preserving effect balance, subject to device and output limits.
把摇杆拉回中央的基础回中力。其他所有力都叠加在它之上。太低,正常飞行中摇杆会发软;太高,它会与你的手较劲,并掩盖叠加其上的细微提示。
调高: 更硬的回中,更抗手。
调低: 更软的杆,只靠气动载荷。
设定理由: The profile combines sustained transport resistance with separate radial-engine cues. The baseline spring is 0.74. Its low-speed blend reaches baseline strength at 65 KIAS.
Exact product, simulator declarations and configuration featuresLocal Legend VIII: DHC-4 CaribouMicrosoft Flight Simulator Adds New Plane To Local Legend Series中央附近弹簧保持安静的小中立区,让静止时的微小移动不会咔嗒作响。更宽更安稳但更松,更窄更精确但可能在中央附近抖动。
调高: 更安静但更松的中央,旷量更大。
调低: 更紧的中央,静止时可能抖动。
设定理由: Sets travel around the centre before the baseline spring resists. Smaller values engage it sooner.
作用于两条持续轴载荷的主缩放,在它们各自的独立平衡之前施加。配置文件通常不动它,而是调校两条轴载荷。
调高: 两轴载荷一同加重。
调低: 两轴一同减轻。
设定理由: The aerodynamic-load gain is 0.8 with an indicated-speed reference of 140 KIAS. This supplies speed-dependent loading alongside the spring.
启用低速弹簧介入窗口(上面的起始/全强度节数)。关闭时弹簧在所有速度下恒定。
设定理由: Allows baseline spring strength to rise with indicated airspeed where the control law permits it.
在静止、空速尚未产生气动力之前,弹簧还剩多少。下限高,停机时摇杆结实;下限低,则是停放轻型飞机那种钢索松弛的感觉。
调高: 停机和滑行时杆更结实。
调低: 停机时杆发软,只随速度苏醒。
设定理由: Sets low-speed spring strength as a fraction of baseline when blending is enabled. One keeps full strength.
弹簧从低速下限开始向全强度攀升的空速:起飞滑跑中操纵面"苏醒"的那一刻。
设定理由: Sets the IAS where the low-speed spring blend starts rising. This is a feel threshold, not a flight limit.
弹簧达到全强度的空速。从起点到这里,随着气流在操纵面上增强,回中逐渐变硬。
设定理由: Sets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it.
气动载荷达到设计满值的指示空速。它把整条载荷曲线锚定在飞机真实的速度范围:172在110节就载满,喷气机要晚得多。
调高: 载荷来得更晚;杆轻到更高速度。
调低: 载荷来得更早,巡航更沉。
设定理由: Sets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit.

设定理由: The high-speed spring-stiffening gain is 0.15. It strengthens the permitted spring response above 65 KIAS, with the squared-speed ratio capped at 5.
速度驱动的中央变硬上限,防止高速飞行把弹簧无限上紧。
调高: 高速允许更多总硬化。
调低: 硬化更早封顶。

由升降舵偏转和空速产生的持续俯仰载荷,独立于横滚调校。这是决定机型俯仰重量的主杠杆。它不影响副翼、弹簧、配平或抖振力。
调高: 速度下持续俯仰力更重。
调低: 升降舵更轻,握持更省力。
设定理由: Scales pitch aerodynamic loading; pitch spring travel and trim responses are separate settings.
每个稳态俯仰或横滚力到达设备前的上限,防止猛烈机动中砸击或饱和硬件。
调高: 削波前更高的稳态力峰值。
调低: 更柔的上限;猛烈机动更早被抹平。
设定理由: Caps directed-force output. Native spring effects and device limits remain separate.
升降舵配平缓解持续俯仰力、移动杆的安定位置的强度。在100 %时,配平得当的飞机不需要保持压力——正是真实飞行中"用配平消掉载荷"的流程。
调高: 配平消掉更多持续力;100 %时满配平可完全抵消。
调低: 即使配平也仍要持续用力。
设定理由: Configured pitch relief is independent of the cargo-pod selection. Pitch relief is off, with stored authority 0; roll authority is 0.
Exact product, simulator declarations and configuration featuresLocal Legend VIII: DHC-4 CaribouMicrosoft Flight Simulator Adds New Plane To Local Legend Series横滚配平的同类缓解。多数通航机型没有真正的副翼配平,所以保持为零;有横滚配平的机型获得相应的值。
调高: 横滚配平消掉更多持续力。

接近失速及失速警告响起时的机体抖动:这副机翼宣告不满的音量。断失干脆的机型抖振收敛,让喇叭承担警告。
调高: 更强的失速前颤抖。
调低: 更含蓄的机翼;警告交给喇叭。
设定理由: Sets stall-buffet strength. Zero removes the cue without changing simulator stalls or warnings.

反推或桨叶beta区工作时的滑跑振动。无反推机型为零。
调高: 反推下更粗糙的滑跑。
调低: 更含蓄的反推。
设定理由: Sets reverse-thrust vibration with valid reverser and engine conditions. Zero removes the cue.
从慢车到全功率跟随转速的持续动力装置振动——前方有东西在烧油的永恒提醒。
调高: 杆里更多发动机。
调低: 更含蓄的发动机。
设定理由: Sets estimated engine vibration using configured telemetry and response, not measured cockpit vibration.
仅在模拟器报告襟翼舵面确实移动时的持续振动。它跟随真实作动器的运动和故障,而非估算的计时器。
调高: 襟翼移动中更多振动。
调低: 更含蓄的襟翼行程。
设定理由: Sets texture from observed flap movement; a command without movement does not establish the cue.
自动驾驶指令可以让杆实际移动多远。在MSFS中保持极小,因为移动的轴可能被读回为飞行员输入;零则完全禁用跟随。
调高: 自动驾驶让你的杆移动得明显更多。
