First officer preflight — part 5

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.

​

1. ENG display control — Set

Set the engine display controls according to the approved setup.

Checks and evidence

Expected response: SetVerification: Require the intended display-selector state and display contents.

​

2. Engine instruments — Check

Check both engines against the applicable phase criteria, using valid engine indications.

Checks and evidence

Expected response: CheckVerification: Require valid readings and explicit limits/acceptance criteria for this phase.

​

3. Cargo fire panel — Check

Perform the approved cargo-fire panel inspection/test, rather than merely issuing its test action.

Checks and evidence

Expected response: CheckVerification: Require the specified cargo-fire test indications and restored state.

​

4. VHF NAV radios — Set for departure

Tune and verify the departure navigation radios using the configured conventional NAV or MMR receiver and approved frequencies/courses.

Checks and evidence

Expected response: Set for departureVerification: Verify the active receiver frequency and intended identification/course where available.

​

5. Audio control panel — Set

Apply the mission’s transmit/receive selections and volumes; do not assume a radio is audible from its frequency alone.

Checks and evidence

Expected response: SetVerification: Verify requested audio selection and communication capability with the environment.

​

6. ADF radios — Set

Apply the approved ADF frequencies/selections for the mission only where required.

Checks and evidence

Expected response: SetVerification: Verify actual active ADF frequency and indication.

​

7. Weather radar panel — Set

Set weather radar according to the approved phase/profile, distinguishing the radar’s actual operating mode from showing its overlay on the ND.

Checks and evidence

Expected response: SetVerification: Read the radar operating mode and display state separately.

​

8. Transponder panel — Set

Set code and mode from the mission/clearance, then verify both. Code and mode are separate requirements.

Checks and evidence

Expected response: SetVerification: Read back the actual code and mode; for explicit TA/RA or STBY select that named mode.

​

9. Stabilizer trim — Guard closed

Verify the stabilizer-trim guard required here; do not confuse this with entering takeoff trim.

Checks and evidence

Expected response: Guard closedVerification: Observe the actual relevant guard.
