Whiteman approached the Austro-powered DA40 NG with experience of the original prototype and earlier production versions. Flying G-SUEO with its regular demonstration pilot, Mark, he appreciated the simple power control and comfortable seating, although mastering the Garmin displays would require more study. Initial acceleration was strong, but the departure did not deliver the improvement he had hoped for. Retracting the flaps brought a noticeable reduction in the modest early climb.
Once established, the familiar appeal returned: light, well-coordinated controls, a useful mechanical trimwheel and excellent visibility made formation flying and general manoeuvring a pleasure. The aeroplane required continuing right-pedal pressure, which Mark suspected might reflect that particular aircraft's rigging; Whiteman did not establish it as a fleet characteristic. His final assessment remained mixed. He admired the DA40's handling and recognised the diesel's potential economy, while wishing its takeoff and initial climb felt more convincing.
Turner evaluated the DA40 as a prospective training aircraft and found plenty to keep a student engaged. Its low seating position and broad view made the runway feel close, while the initial takeoff required deliberate directional control. In the air, he found the stick easy to adopt and the controls light without becoming vague. Once properly trimmed, the aircraft held its attitude well, but its clean airframe demanded anticipation when levelling off or preparing to descend.
An overcast formed beneath the demonstration flight, so the return included an IFR clearance and vectors to an ILS. That gave Turner a practical opportunity to explore the workload of an instrument approach before breaking into visual conditions for landing. He finished the flight smiling and considered the Diamond a promising trainer for future professional pilots. His praise included the demands it placed on rudder coordination and energy management, alongside reservations about ground ventilation, storage space and the attention required during transition.
Lee wanted to experience the DA40 XLS on an ordinary outing, so he joined distributor demonstration pilot Robert Stewart for a trip from Long Beach to Santa Paula. The wraparound view immediately impressed him, and he welcomed the manual trimwheel after initially fumbling with electric trim. Climbing out toward the coast, he began to appreciate how much of the surrounding landscape was visible from ahead of the wing.
The journey combined low-speed handling demonstrations, music through the headsets and a look at the Garmin synthetic-vision display before an arrival among Santa Paula's classic aircraft. Lee had expected to dislike a modern composite aeroplane, but found that the technology left plenty of opportunity to enjoy hand-flying. Returning to Long Beach, he was reluctant to walk away.

This profile selects NHAdrian / Alabeo Alabeo DA40 Expansion Pack for X-Plane 12.
Mechanical linkage motivates airspeed-sensitive stick resistance. Spring resistance builds with the selected airspeed response. A separate aerodynamic term adds speed-dependent control load.
The DA40 elevator tab supplies pitch pressure relief, unlike the DA20’s spring-preload system. Pitch-trim relief is off. Autopilot following is off.
The DA40’s elevator and ailerons use pushrods, with cables operating the rudder. A Bowden cable drives the elevator trim tab, and electric flaps select their named positions. Lycoming XLS and diesel NG versions retain different propulsion and cockpit equipment.
NHAdrian’s expansion enables the older Alabeo piston DA40 in XP12; it is separate from a developer-native diesel NG.
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 : Mechanical linkage motivates airspeed-sensitive stick resistance. The baseline spring is 0.74. Its low-speed blend reaches baseline strength at 65 KIAS.

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 0.8 with an indicated-speed reference of 130 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 0.15. It strengthens the permitted spring response above 65 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 : The DA40 elevator tab supplies pitch pressure relief, unlike the DA20’s spring-preload system. Pitch relief is off, with stored authority 0; roll authority is 0.

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.
