Aileron trimAileron trim

Aileron trim avec A/P engagé est interdit (Limitations). L’A/P tient les ailes à plat ; le trim ne se sent qu’au disconnect → coup d’aileron brutal.Aileron trim with A/P engaged is prohibited (Limitations). A/P holds wings level; trim is felt only on disconnect → abrupt aileron pull.

A/P HOLDS WINGS LEVEL Trim input is masked while engaged On disconnect → abrupt aileron pull toward trim Rudder trim: allowed — small 0.5 s shots, wait 3–5 s
Piège aileron trim — wings level masque l’entrée.Aileron trim trap — wings-level masks the input.

Autorisé / recommandé (technique FCTM) avec A/P engagé — contrairement à l’aileron.Allowed / recommended (FCTM technique) with A/P engaged — unlike aileron.

Les pédales bougent avec le trim (feedback visible). Petits coups ~0,5 s ; attendre 3–5 s ; surveiller la réponse volant.Pedals move with trim (visible feedback). Small shots ~0.5 s; wait 3–5 s; monitor wheel response.
