### Mises en garde et notes

<Warning>
  **Démarrage interrompu** - Condition Lever FUEL OFF immédiatement. Limite ITT au démarrage 920 °C pour max 20 s. Minimum 30 s entre les tentatives de démarrage.
</Warning>

<Note>
  **Roulage** - Vérification des freins au premier mouvement : *"Brakes checked, pressure \_\_\_"*.
</Note>

<Note>
  **Atterrissage** - Toucher des roues : Power Levers DISC - GROUND RANGE - Reverse. Ralenti inversé à 60 kt.
</Note>
