General
Begin shutdown in the assigned parked condition. Set the parking brake and establish the required electrical supply before moving engine start levers to CUTOFF. The checklist requires fuel pump switches OFF without a listed APU exception. Engine bleed ON is a switch-selection requirement, not an indication that a stopped engine supplies air. Account for the assigned APU and electrical/air configuration. With Airside Services active, anti-collision OFF can initiate deboarding and cargo unloading.Secure
Select the secure procedure when required after shutdown. Its four checks are IRS OFF, emergency-exit lights OFF, window heat OFF and packs OFF. A battery-OFF or mandatory APU-OFF step is not included. Record the actual end condition; secure-checklist completion alone does not establish cold-and-dark.1. Engine anti-ice — Off
Apply the required anti-ice state to the applicable engines; resolve As needed before issuing a command.Checks and evidence
Checks and evidence
Expected response: OFFVerification: Require switch-state and corresponding system/annunciator evidence.
2. Hydraulic panel — Set
Use the approved hydraulic-panel setup; do not interpret Set as a command to toggle every pump.Checks and evidence
Checks and evidence
Expected response: SetVerification: Verify required pump positions, pressures/quantities and relevant indications.
3. Recirculation fan — As needed
Resolve the required fan state(s) for this shutdown context and change only as necessary.Checks and evidence
Checks and evidence
Expected response: As neededVerification: Read back each required fan selection with validated state decoding.
4. Pack switches — Auto
Set both pack switches AUTO. Verify both selector positions using the applicable detent decoding.Checks and evidence
Checks and evidence
Expected response: AUTOVerification: Read both selector states and confirm the requested detent.
5. Isolation valve — Open
Select the isolation-valve selector OPEN. Verify the selector position; verify actual valve state separately when required.Checks and evidence
Checks and evidence
Expected response: OPENVerification: Decode and compare the selector position; verify physical valve state separately where required.
6. Engine bleed — On
Establish ON for the applicable engine-bleed switches at the supplied shutdown step.Checks and evidence
Checks and evidence
Expected response: ONVerification: Require the engine-bleed switch states, separate from whether an engine currently supplies air.
7. APU bleed — On
Select APU bleed ON in accordance with the applicable air-supply configuration. Verify the required switch and valve indications.Checks and evidence
Checks and evidence
Expected response: ONVerification: Require APU bleed-switch/valve state and relevant source evidence.
8. Exterior lights — As needed
Apply the approved lighting-panel setup without inventing which lights Set includes.Checks and evidence
Checks and evidence
Expected response: As neededVerification: Verify the requested lights, using the configured landing-light variant.
9. Flight director — Off
Set the required flight-director switch(es) OFF, checking current state before using a toggle.Checks and evidence
Checks and evidence
Expected response: OFFVerification: Verify the applicable flight-director switches are OFF.
