Peng Chen · CC BY-SA 4.0 · Airbus A400M Atlas picturedThe A400M occupies the space between smaller tactical transports and larger strategic airlifters. Its high wing, rear loading ramp and four large propellers are organised around moving troops and bulky cargo. Airbus developed it as a replacement for older transport fleets including the Transall C-160.
The simulated aircraft combines cargo handling and transport missions with an electronic flight deck, whose controls are described in the included manual.

Ralph’s 2025 circumnavigation combined copilot and loadmaster training, a public appearance at Avalon and a cargo pickup in Washington. Newer crew members gained experience far from home during the A400M deployment.
First flight: 11 December 2009
Christoph had wanted to visit the cockpit whenever his family travelled by air. After nine years flying the Transall, conversion to the A400M brought a much more automated working environment. He still found takeoff exciting, describing the aircraft’s acceleration as something that brought both a smile and goosebumps.
One particularly enjoyable assignment came during his aircraft-commander training in 2017, when he flew the type to Cape Town. Clear weather on arrival and departure allowed the crew to enjoy a view around Table Mountain. His interview sets that memory beside the more routine work of carrying people and equipment to Lithuania. Transport flying appealed to him for its crew friendships and the variety of places the job could take him.
Ralph regarded the round-the-world journey as a kind of farewell assignment before his planned retirement. It was also a working trip: two copilots were building experience through line training, and the loadmasters had younger colleagues to teach. The route joined training, an Australian airshow and a cargo pickup in Washington.
At Avalon, meeting other crews and welcoming visitors into the aircraft made the presentation enjoyable. The destinations sounded like a holiday itinerary, but Ralph emphasised the need for fuel stops, rest and adjustment to changing time zones. After weeks away, home had a renewed attraction.
Knoll explained that the nonstop Hawaii trial required two crews to alternate through a very long working day. Tanker support came from the wing’s own A400Ms, and the route passed close to the polar region. The flight brought together tasks that the crews had previously practised in the simulator.
His strongest emphasis was on concentration. Having personally flown close formation, he described how unusual it feels to bring two large transports near each other, and how refuelling demands still greater precision. Maintaining that focus after many hours awake added another challenge to the trial. The interview does not identify Knoll as the sole operating pilot of the flight.

This starting point selects Airbus A400M Atlas. Its aircraft-level settings do not select a particular developer’s custom systems.
The spring stays independent of airspeed. Directed aerodynamic loading is omitted.
Pitch-trim relief is off. Autopilot following is off.
Airbus describes fly-by-wire controls for the A400M and autopilot/flight-director assistance with aerial delivery. Its four turboprops and cargo systems give the transport a different equipment arrangement from an Airbus passenger jet. The manufacturer overview establishes this electronic-control architecture without providing a cockpit-inceptor force curve or an external autopilot movement signal.
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 fixed centre is a fly-by-wire control approximation; the available manufacturer overview does not quantify mechanical inceptor feel. The baseline spring is 0.55. Low-speed spring blending is off.
Airbus A400MUne 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.
Pourquoi ici : The centre preload is 0.03. It ramps outside the 0.01 deadband across 0.05 travel, shaping the passive centre independently of aircraft autotrim.
Pourquoi ici : Sets the travel used to ramp in centre preload. Wider intervals make its onset more gradual.
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 stored 0.04 aerodynamic-load gain is inactive under the fixed-centre control law.
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 : Adds permitted spring resistance above the full-blend speed. Zero removes this high-speed increase.
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 1 and 1, respectively. These stored weights do not create directed aerodynamic loading while that term is inactive. The pitch spring-travel curve reaches output 1 at input 1. The roll spring-travel curve reaches output 0.3 at input 1. Spring-travel response contributes separately to axis balance.
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 : Hardware trim-centre movement remains separate from the transport's electronic flight-control and aerial-delivery guidance. Pitch relief is off, with stored authority 0; roll authority is 0.
Airbus A400MLe 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.
Whether this feature is active in this profile.
Pourquoi ici : Applies the configured pitch and roll spring travel curves.
Pourquoi ici : Sets response at the second pitch-curve point; it is an endpoint only if its input position is full travel.
Pourquoi ici : Sets response at the second roll-curve point; its input position and other points determine the travel law.
Whether this feature is active in this profile.
Pourquoi ici : Retained for compatibility and group membership. Trim relief, rather than this flag, controls centre movement.
Whether this feature is active in this profile.
Pourquoi ici : Allows trim relief with supported control law and valid telemetry. Axis authorities set its amount.
Whether this feature is active in this profile.
Pourquoi ici : Enables local force trim, separate from aircraft-owned trim and add-on integration qualification.
Whether this feature is active in this profile.
Pourquoi ici : Allows load-factor changes to modify permitted spring laws. Passive fly-by-wire feel can suppress it.
Whether this feature is active in this profile.
Pourquoi ici : Enables rate damping with the configured coefficients and control law.
Whether this feature is active in this profile.
Pourquoi ici : Autopilot following is off; the configured spring and load retain the hardware feel. Separate neutral hold is on at strength 0.28, when a supported autopilot state admits it.
Whether this feature is active in this profile.
Pourquoi ici : Permits centering hold during a supported AP state, separate from following a moving target.
Pourquoi ici : Sets admitted AP neutral-hold strength; inactive while neutral hold is disabled.
Whether this feature is active in this profile.
Pourquoi ici : Enables aerodynamic cues; each still needs nonzero strength and its simulator conditions.
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.
Where this effect begins fading in.
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.
Whether this feature is active in this profile.
Pourquoi ici : Permits shaker at supported warning conditions; the switch does not establish aircraft equipment.
Whether this feature is active in this profile.
Pourquoi ici : Enables ground effects; each still needs its own strength and contact or motion telemetry.
Whether this feature is active in this profile.
Pourquoi ici : Enables engine cues with nonzero settings and valid running-engine telemetry.
