Vue d’ensembleOverview

Normal Flight Controls : ailerons / elevators (hyd A+B + reversion manuelle), rudder (A+B+Standby, pas de reversion), spoilers, flaps/slats, trim (stab / speed / mach). Les titres ici sont le savoir système — les étapes QRH restent dans Urgence / qrh-9-*.Normal Flight Controls: ailerons / elevators (hyd A+B + manual reversion), rudder (A+B+Standby, no reversion), spoilers, flaps/slats, trim (stab / speed / mach). Titles here are system knowledge — QRH steps stay in Emergency / qrh-9-*.
