The Fortress began as Boeing’s Model 299, first flown in 1935, and developed through successive wartime versions to the B-17G. It became closely associated with the Eighth Air Force’s bombing campaign over Germany and occupied Europe. Boeing, Douglas and Vega built the aircraft; crews continued using some survivors for civil work after the war.
The museum’s B-17F, 42-29782, was built in Seattle in 1943 and served principally in training. Its later life included a park war memorial, aerial spraying, firefighting and appearances in Tora! Tora! Tora! and Memphis Belle. Restoration returned it to military appearance as Boeing Bee. Its screen roles and restored equipment are part of that individual aircraft’s later history.
First flight: 28 July 1935
Bjorkman used money she had intended for retirement to buy a B-17 copilot checkout at an EAA auction. She already had considerable tailwheel experience, but the largest aircraft she had flown was a Piper Aztec. Additional light-twin practice helped her prepare, while the sight of the Fortress in its hangar made the scale of the next step unmistakable. Starting it also introduced her to the coordinated work of the instructor and ground crew.
Once airborne, she found the controls unexpectedly light and the aircraft comfortable to manoeuvre. The weather made landing a different experience: Davis coached her through a demanding crosswind and helped with asymmetric power. She finished that first landing tired, then returned the next day for more practice. The achievement was specific and personal: a second-in-command endorsement in an aircraft she had long wanted to fly.
Nelms remembered the shock of an encounter with antiaircraft fire. A burst beneath the aircraft made him frightened, followed by embarrassment at his own reaction. He describes gathering himself and checking on the crew. Their responses, including a radio operator joking that nobody had asked about him yet, gave that frightening moment an unexpectedly ordinary human exchange.
Another memory was much harder to carry. He had eaten breakfast with a friend before a mission, then watched that friend’s aircraft suffer a hit and descend out of control. In the museum interview, the contrast between their familiar morning conversation and the loss later that day remains vivid. His recollections give the Fortress a crew’s perspective: fear, concern for the people aboard and the sudden absence of someone who had been part of everyday life.
Clark arrived at Las Vegas Army Airfield in 1944 after training in a small twin. The B-17 cockpit seemed enormous and crowded with unfamiliar instruments, and he learned its work through gunnery-training flights before joining a crew bound for England. That same posting introduced him to Marie Mountain, a WASP pilot. An invitation to listen to Debussy at the library began the relationship that led to their marriage.
With the 100th Bomb Group, he discovered how much formation flying demanded physically. Departure and assembly could take place in poor weather, followed by long periods wearing an oxygen mask and cold-weather equipment. An electrically heated suit solved one problem and created another: perspiration fogged his goggles. These practical discomforts sit beside the larger events in his account, showing how much effort simply occupying the copilot’s seat could require.
Boeing developed the B-17 during the 1930s for the United States Army Air Corps. It became closely associated with the European air war, but the aircraft also served in transport, maritime patrol and rescue work. The B-17G represented in the simulator catalogue is a particular production version, not a label for every Flying Fortress configuration.
This profile selects MicroProse B-17G Flying Fortress for MSFS 2024.
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.
MicroProse's B-17G manual describes four R-1820 engines, constant-speed propellers and trim tabs on all three axes. Its later change log records flight-model, trim, flap and centre-of-gravity corrections, so early feature descriptions and cockpit-autopilot operation remain version-sensitive. Khamsin's separate X-Plane B-17G listing marks work in progress; that reference must not be presented as a released implementation.
MicroProse's MSFS 2024 B-17G has version-sensitive trim/flap/CG/autopilot changes. Advertised post-launch crew/maintenance features are not assumed complete.
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 : The selected mechanical-control loading belongs to the named B-17G reference; four engine cues do not establish a multiple of yoke hand force. The baseline spring is 0.74. Its low-speed blend reaches baseline strength at 70 KIAS.
B-17G Flying FortressB-17G Flying FortressUne 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 0.46 with an indicated-speed reference of 150 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 70 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 0.65 and 0.86, 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 : Three-axis trim tabs support separate pitch and roll pressure relief, with developer revision differences kept visible. Pitch authority 0.3 provides load relief and permitted centre movement; roll authority is 0.13.
B-17G Flying FortressB-17G Flying FortressLe 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.
