# First officer preflight — part 6

> First officer preflight — part 6: conditions, actions and checks for the Boeing 737-800.

Use this procedure when its prerequisites apply. Confirm each required aircraft state before acknowledging the corresponding checklist item.

## General

Complete the preliminary, CDU, captain and first-officer procedures in the applicable ground configuration. Retain the side-specific requirements. A captain instrument or control does not satisfy an independent first-officer or standby check.

Use the assigned detailed panel procedures for Set, Check, Test and Pass requirements. Observe the specified result and restore the required operating configuration after each actual cockpit test. Do not operate a system merely because its control appears in the reference list.

Complete loading, performance preparation and the required equipment checks before progressing to the dependent departure procedures. Where an item requires an external inspection or crew adjustment, retain the assigned verification or explicit scenario exclusion.
