Development milestones
First flight: May 15, 1963 (Model 87) January 24, 1964 (Model 65-90)
Developed from: Beechcraft Queen Air
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. The named variants identify the airframe and equipment described in each source.

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.
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.
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 starting point selects Beechcraft King Air B200. Its aircraft-level settings do not select a particular developer’s custom systems.
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 enabled for supported control references.
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 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.
L'échelle globale finale appliquée à tout ce que produit le modèle, avant la limite du périphérique.
Plus : tout (ressort, charges, effets) se renforce ensemble.
Moins : tout s'adoucit ensemble.
Pourquoi ici : Scales overall profile strength while preserving effect balance, subject to device and output limits.
La force de rappel de base qui ramène le manche au neutre. Toutes les autres forces s'empilent dessus. Trop faible, le manche paraît mou en vol normal ; trop forte, elle lutte contre la main et masque les signaux plus fins.
Plus : un centrage plus ferme qui résiste davantage à la main.
Moins : un manche plus mou qui ne compte que sur la charge aérodynamique.
Pourquoi ici : Published 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 90 KIAS.
Exact product researchBeechcraft King Air C90B POHUne petite zone neutre autour du centre où le ressort reste muet, pour que les micro-mouvements à l'arrêt ne vibrent pas. Plus large, c'est plus calme mais plus lâche ; plus étroite, plus précis mais parfois nerveux au neutre.
Plus : un centre plus calme mais plus lâche, avec plus de jeu.
Moins : un centre plus serré qui peut vibrer au repos.
Pourquoi ici : Sets travel around the centre before the baseline spring resists. Smaller values engage it sooner.
Une échelle maîtresse sur les deux charges d'axe, appliquée avant leur équilibre individuel. Les profils la laissent en général en place et règlent les deux axes.
Plus : les deux axes chargent plus fort.
Moins : les deux axes s'allègent ensemble.
Pourquoi ici : The aerodynamic-load gain is 0.68 with an indicated-speed reference of 190 KIAS. This supplies speed-dependent loading alongside the spring.
Active la fenêtre d'engagement basse vitesse du ressort (début/plein en nœuds ci-dessus). Désactivé, le ressort est constant à toute vitesse.
Pourquoi ici : Allows baseline spring strength to rise with indicated airspeed where the control law permits it.
La part du ressort qui survit à l'arrêt, avant que la vitesse ne crée la moindre force aérodynamique. Un plancher haut garde le manche ferme au parking ; un plancher bas donne le jeu de câbles d'un avion léger au parking.
Plus : un manche plus ferme au parking et au roulage.
Moins : un manche mou au parking qui ne s'éveille qu'avec la vitesse.
Pourquoi ici : Sets low-speed spring strength as a fraction of baseline when blending is enabled. One keeps full strength.
La vitesse à laquelle le ressort quitte son plancher basse vitesse vers la pleine raideur : le début du réveil des commandes au roulage de décollage.
Pourquoi ici : Sets the IAS where the low-speed spring blend starts rising. This is a feel threshold, not a flight limit.
La vitesse où le ressort atteint sa pleine raideur. Entre le début et ce point, le centrage se raffermit avec le vent relatif.
Pourquoi ici : Sets the IAS where the low-speed blend reaches baseline strength; high-speed stiffening also uses it.
La vitesse indiquée où la charge aérodynamique atteint son niveau de conception. Elle ancre toute la courbe au domaine réel : un 172 charge dès 110 nœuds, un jet bien plus tard.
Plus : les charges arrivent plus tard ; le manche reste léger jusqu'à plus vite.
Moins : les charges arrivent plus tôt et la croisière pèse davantage.
Pourquoi ici : Sets the IAS reference for aerodynamic loading. It is an estimate, not published cruise TAS or a flight limit.
Combien le centrage lui-même se raidit avec la vitesse, en plus des charges de braquage. Zéro garde un centre constant ; plus fait centrer dur en croisière et souple en tour de piste.
Plus : un centre qui durcit nettement avec la vitesse.
Moins : une sensation de centre constante à toute vitesse.
Pourquoi ici : The high-speed spring-stiffening gain is 0.1. It strengthens the permitted spring response above 90 KIAS, with the squared-speed ratio capped at 5.
La limite haute du raidissement lié à la vitesse, pour que le vol très rapide ne remonte pas le ressort sans borne.
Plus : plus de raidissement total permis à haute vitesse.
Moins : le raidissement se bride plus tôt.
Pourquoi ici : Limits the squared airspeed ratio used for high-speed spring stiffening; it is not a device-force cap.
La charge de roulis soutenue issue du braquage d'ailerons et de la vitesse, équilibrée indépendamment du tangage. Avec la charge de profondeur, elle fixe l'harmonie des commandes dont parlent les essais.
Plus : des efforts de roulis plus lourds.
Moins : des ailerons plus légers, plus vifs.
Pourquoi ici : Roll and pitch aerodynamic scales are 0.72 and 1, respectively. They set the aerodynamic axis balance. No custom spring-travel curve is enabled.
La charge de tangage soutenue issue du braquage de profondeur et de la vitesse, équilibrée indépendamment du roulis. Le levier principal du poids en tangage d'un type. Il ne touche ni ailerons, ni ressort, ni trim, ni buffet.
Plus : des efforts de tangage soutenus plus lourds en vitesse.
Moins : une profondeur plus légère, moins musclée à tenir.
Pourquoi ici : Scales pitch aerodynamic loading; pitch spring travel and trim responses are separate settings.
Un plafond par force stable de tangage ou roulis avant le périphérique : la garde contre le claquement ou la saturation du matériel en manœuvre forte.
Plus : des pics de force stable plus élevés avant écrêtage.
Moins : un plafond plus doux ; les manœuvres dures s'aplatissent plus tôt.
Pourquoi ici : Caps directed-force output. Native spring effects and device limits remain separate.
Combien le trim de profondeur soulage l'effort tenu et déplace le point de repos du manche. À 100 %, un avion bien compensé ne demande aucune pression : le geste réel de compenser la charge.
Plus : le trim retire plus d'effort tenu ; à 100 %, plein trim l'annule.
Moins : vous continuez à tenir de l'effort même compensé.
Pourquoi ici : Mechanical elevator trim supports pitch relief, while aileron trim is separate from rudder trim. The selected authorities approximate those axis responses. Pitch authority 0.3 provides load relief and permitted centre movement; roll authority is 0.14.
Exact product researchBeechcraft King Air C90B POHLe même soulagement pour le trim de roulis. La plupart des avions légers n'ont pas de vrai trim d'ailerons, donc zéro ; les types qui en ont reçoivent une valeur adaptée.
Plus : le trim de roulis retire plus d'effort tenu.
Moins : le trim de roulis fait moins.
Pourquoi ici : Scales supported roll-trim relief and permitted centre movement. Zero removes roll response.
Vibration de roulement issue de la vitesse des roues et du revêtement : la texture du bitume, de l'herbe ou du gravier sous le train.
Plus : une texture de surface plus forte dans le manche.
Moins : un roulage plus lisse.
Pourquoi ici : Sets rolling texture strength, modified by speed, surface and undercarriage configuration.
Chocs courts et distincts des joints, ornières et surfaces rugueuses : la ponctuation au-dessus du grondement continu.
Plus : des chocs plus nets des joints et ornières.
Moins : des détails de sol plus doux.
Pourquoi ici : Sets gear-bump texture during ground motion, separate from touchdown impact.
Buffet de cellule à l'approche du décrochage et pendant l'avertisseur : la voix de cette aile quand elle est mécontente. Les types à décrochage franc reçoivent un buffet modéré, le klaxon porte l'alerte.
Plus : un tremblement pré-décrochage plus fort.
Moins : une aile plus discrète ; le klaxon porte l'alerte.
Pourquoi ici : Sets stall-buffet strength. Zero removes the cue without changing simulator stalls or warnings.
Buffet transsonique près de la limite de Mach. Parlant pour les jets près de MMO, zéro pour pistons et turbopropulseurs qui n'y vont jamais.
Plus : un buffet transsonique plus fort près de la limite de Mach.
Moins : un vol plus lisse à haut Mach.
Pourquoi ici : Sets high-Mach buffet strength; onset and full-strength thresholds are separate.
Vibration basse fréquence de cellule avec les volets dans le vent, dans la fenêtre où ils travaillent vraiment l'air.
Plus : un vol plus rugueux volets au travail.
Moins : des volets d'approche plus doux.
Pourquoi ici : Sets flap buffet at the configured position and speed gates. Flap movement texture is separate.
Le tambourinement du train rentrant sorti dans le flux. Zéro pour les trains fixes, dont la cellule ne change jamais de forme.
Plus : plus de tambourinement train sorti.
Moins : un vol train sorti plus propre.
Pourquoi ici : Sets gear aerodynamic buffet; movement and ground-contact cues are separate.
Le vibreur de manche dédié, déclenché par l'avertisseur de décrochage de l'avion. Seuls les types à vrai vibreur reçoivent une valeur ; les autres comptent sur buffet et klaxon.
Plus : un vibreur plus dur.
Moins : un vibreur plus discret.
Pourquoi ici : Sets triggered shaker strength; inactive while the shaker feature is disabled.
Le coup unique au toucher, proportionnel au taux de chute : un kiss se murmure, une arrivée ferme cogne.
Plus : un coup plus dur au toucher.
Moins : des arrivées plus douces.
Pourquoi ici : Sets landing-impact strength; landing telemetry and response shape determine the pulse.
Vibration de roulage sous inversion de poussée ou plage bêta. Zéro pour les types sans reverse.
Plus : un roulage plus rugueux sous reverse.
Moins : une reverse plus discrète.
Pourquoi ici : Sets reverse-thrust vibration with valid reverser and engine conditions. Zero removes the cue.
Vibration continue du moteur suivant le régime du ralenti à la pleine puissance : le rappel permanent que quelque chose brûle du carburant devant.
Plus : plus de moteur dans le manche.
Moins : un moteur plus discret.
Pourquoi ici : Sets estimated engine vibration using configured telemetry and response, not measured cockpit vibration.
Vibration continue seulement pendant que le simulateur signale les volets réellement en mouvement. Elle suit la course réelle et les pannes, pas un minuteur estimé.
Plus : plus de vibration volets en mouvement.
Moins : des courses de volets plus discrètes.
Pourquoi ici : Sets texture from observed flap movement; a command without movement does not establish the cue.
Jusqu'où les ordres du pilote automatique peuvent bouger le manche physique. Minuscule dans MSFS, où un axe déplacé peut être relu comme entrée pilote ; zéro coupe le suivi.
Plus : le pilote automatique bouge visiblement plus votre manche.
Moins : un suivi à peine perceptible.
Pourquoi ici : Sets admitted AP-follow gain, not a percentage of travel. Runtime ownership and input limits still apply.

Where this effect reaches full strength (or has fully faded, for washouts).
Plus : a more gradual build to a later peak.
Moins : a quicker build.
Pourquoi ici : Sets the final flap index for detent normalization. UP plus three detents uses maximum index3.

Plus : the effect begins later.
Moins : it begins earlier.
Pourquoi ici : Sets the first flap detent that admits buffet; this is a handle index, not degrees.
