1) Les 3 axes et commandes<\/h1>\n\n\n\n
    \n
  • Tangage (pitch)<\/strong> \u2192 autour de l\u2019axe transversal.
    Commande :<\/strong> manche\/volant avant\/arri\u00e8re<\/strong> \u2192 profondeur<\/strong> (ou stabilator).
    Effet :<\/strong> nez haut\/bas \u2192 change l\u2019incidence donc la vitesse<\/strong>.<\/li>\n\n\n\n
  • Roulis (roll)<\/strong> \u2192 autour de l\u2019axe longitudinal.
    Commande :<\/strong> manche gauche\/droite<\/strong> \u2192 ailerons<\/strong>.
    Effet :<\/strong> incline les ailes \u2192 d\u00e9but du virage<\/strong>.<\/li>\n\n\n\n
  • Lacet (yaw)<\/strong> \u2192 autour de l\u2019axe vertical.
    Commande :<\/strong> palonniers<\/strong> \u2192 gouverne de direction<\/strong>.
    Effet :<\/strong> nez gauche\/droite, coordination du virage.<\/li>\n<\/ul>\n\n\n\n

    2) Effets primaires \/ secondaires (\u00e0 retenir)<\/h1>\n\n\n\n
      \n
    • Ailerons<\/strong> : primaire = roulis ; secondaire = lacet inverse<\/strong> (adverse yaw) \u2192 compenser au palonnier<\/strong>.<\/li>\n\n\n\n
    • Profondeur<\/strong> : primaire = tangage ; secondaire = variation de vitesse<\/strong>.<\/li>\n\n\n\n
    • Direction<\/strong> : primaire = lacet ; secondaire = l\u00e9ger roulis<\/strong>.<\/li>\n\n\n\n
    • Puissance<\/strong> : primaire = vitesse\/trajectoire<\/strong> ; secondaires = couple, souffle h\u00e9lice, tendance au roulis\/lacet.<\/li>\n<\/ul>\n\n\n\n

      3) Virage coordonn\u00e9 (la bille au milieu)<\/h1>\n\n\n\n
        \n
      1. Manche vers le virage (ailerons) \u2192 l\u2019avion s\u2019incline.<\/li>\n\n\n\n
      2. Palonnier du m\u00eame c\u00f4t\u00e9<\/strong> pour annuler le lacet inverse (bille centr\u00e9e).<\/li>\n\n\n\n
      3. Tirer l\u00e9g\u00e8rement<\/strong> au manche pour maintenir l\u2019assiette (la portance \u201cperdue\u201d par l\u2019inclinaison).<\/li>\n\n\n\n
      4. Sortie : manche oppos\u00e9 + palonnier oppos\u00e9, rel\u00e2cher la traction.<\/li>\n<\/ol>\n\n\n\n

        4) Volets (flaps)<\/h1>\n\n\n\n
          \n
        • But<\/strong> : plus de portance<\/strong> \u00e0 basse vitesse + tra\u00een\u00e9e<\/strong> pour descendre plus raide sans acc\u00e9l\u00e9rer.<\/li>\n\n\n\n
        • Effets<\/strong> : baisse la vitesse de d\u00e9crochage, tendance souvent nez-bas<\/strong> (selon avion), augmentation de tra\u00een\u00e9e.<\/li>\n\n\n\n
        • Usage<\/strong> : d\u00e9collage court (r\u00e9glage partiel si recommand\u00e9), approche\/atterrissage (paliers, finale).<\/li>\n<\/ul>\n\n\n\n

          5) R\u00e9glages fins<\/h1>\n\n\n\n
            \n
          • Trim<\/strong> (profondeur, parfois aileron\/direction) : supprime l\u2019effort dans le manche\/palonnier \u2192 voler \u201cmains l\u00e9g\u00e8res\u201d.<\/li>\n\n\n\n
          • Pas d\u2019h\u00e9lice (VP)<\/strong> : r\u00e8gle le r\u00e9gime<\/strong> et l\u2019efficacit\u00e9 (climb vs cruise).<\/li>\n\n\n\n
          • Mixture<\/strong> : r\u00e8gle la richesse (puissance\/\u00e9conomie\/altitude).<\/li>\n<\/ul>\n\n\n\n

            6) Deux r\u00e8gles d\u2019or \u00e0 l\u2019atterro (VFR)<\/h1>\n\n\n\n
              \n
            • \u201cAssiette = Vitesse, Puissance = Plan\u00e9\u201d<\/strong> :\n
                \n
              • Corrige la vitesse<\/strong> avec l\u2019assiette.<\/li>\n\n\n\n
              • Corrige la pente<\/strong>\/plan\u00e9 avec la puissance (ou les volets).<\/li>\n<\/ul>\n<\/li>\n\n\n\n
              • Stabiliser t\u00f4t : volets selon la check-list, trim, bille centr\u00e9e<\/strong>.<\/li>\n<\/ul>\n\n\n\n

                7) Au sol<\/h1>\n\n\n\n
                  \n
                • Roulette de nez<\/strong> souvent coupl\u00e9e aux palonniers<\/strong> (+ freinage diff\u00e9rentiel).<\/li>\n\n\n\n
                • Par vent traversier : manche au vent<\/strong> au roulage, palonnier<\/strong> pour garder l\u2019axe.<\/li>\n<\/ul>\n\n\n\n

                  8) Cas particuliers utiles<\/h1>\n\n\n\n
                    \n
                  • Glissade (slip)<\/strong> : aileron d\u2019un c\u00f4t\u00e9 + palonnier oppos\u00e9 \u2192 forte tra\u00een\u00e9e pour perdre de l\u2019altitude sans acc\u00e9l\u00e9rer.<\/li>\n\n\n\n
                  • Vent de travers<\/strong> : approche crabe puis d\u00e9crabage au palonnier en arrondi, ou m\u00e9thode glissade d\u2019axe<\/strong>.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
