How to Use This Checklist
- **Complete the header fields.** Record when the inspection was conducted, who prepared it, and the location, then sign and note the time it was finished along with the real inspection start and end dates. These give the record its identity and its timing.
- **Bring the aircraft onto electrical power.** Carry out the MISE SOUS TENSION ÉLECTRIQUE procedure for electrical power-up as the starting point for everything that follows.
- **Verify the switch and guard positions.** Confirm that the battery switch guard is closed (PROTECTION D'INTERRUPTEUR DE BATTERIE FERMÉE), the standby power switch guard is closed (PROTECTION DE L'ALIMENTATION DE SECOURS FERMÉE), and the alternate flap switch guard is closed (PROTECTION ALTERNÉE DES VOLETS FERMÉE).
- **Check the selector and pump states.** Confirm the wiper selector is off (SÉLECTEUR D'ESSUIE-GLACE FERMÉ) and that the electric hydraulic pumps are off (POMPES HYDRAULIQUES ÉLECTRIQUES ÉTEINTES).
- **Confirm the landing gear lever.** Verify the landing gear lever is down (LEVIER DU TRAIN D'ATTERRISSAGE SORTI) as part of the pre-flight condition of the aircraft.
- **Answer each item on the Yes, No, or N/A scale.** For every guard, switch, selector, pump, and lever item, record Yes when the stated condition — closed, off, or down — is met, No when it is not, and N/A where the item does not apply.
- **Treat a No as a stop point.** Because these items concern the electrical and hydraulic configuration of the aircraft before flight, any item that cannot be confirmed should be resolved before you move on.

What the electrical power-up and pre-flight sequence is
A Boeing 737 pre-flight session begins with bringing the aircraft onto electrical power and then confirming that the switches, guards, selectors, pumps, and levers on the flight deck are in the configuration required before flight. The saying goes that a good pre-flight is boring — and that is the point. The sequence is short and repetitive by design: the same items are checked in the same order every time so that nothing is left to memory or assumption. This checklist follows that sequence as it is used on real 737 flights.
Why the electrical and hydraulic configuration matters
The items in this pre-flight sequence sit at the boundary between a parked aircraft and one that is ready for flight. The battery switch guard, standby power switch guard, and alternate flap switch guard protect switches that should not be disturbed without intent, so each guard is confirmed closed. The wiper selector is confirmed off, the electric hydraulic pumps are confirmed off, and the landing gear lever is confirmed down. Taken together, these checks establish that the aircraft is electrically powered, that protected switches are guarded, and that the hydraulic and landing gear systems are in their expected pre-flight state. If something is out of position here, it affects every step that follows.
What a good pre-flight inspection covers
A complete record of this phase covers both the aircraft configuration and the circumstances of the inspection itself. On the aircraft side, the checklist covers the electrical power-up procedure and the position of six specific controls: battery switch guard, standby power switch guard, alternate flap switch guard, wiper selector, electric hydraulic pumps, and landing gear lever. On the record-keeping side, it captures conducted on, prepared by, location, signature, finished at, and the real inspection start and end dates. Each item is answered on a simple Yes / No / N/A scale, so the state of every control is explicit rather than implied.
How to carry out the pre-flight and power-up checks
For each item on the checklist, confirm the stated condition and record your answer: - Battery switch guard is closed. - Standby power switch guard is closed. - Alternate flap switch guard is closed. - Wiper selector is off. - Electric hydraulic pumps are off. - Landing gear lever is down. Answer **Yes** when the condition is met, **No** when it is not, and **N/A** when the item does not apply. Because a No here indicates a control that is not in its expected pre-flight position, resolve it before continuing. Complete the header and signature fields so the inspection has a name, a place, and a time attached to it.
Where this checklist fits in the flight sequence
The full model covers the sequence used on real B737 flights — electrical power-up, pre-flight, departure clearance, engine, take-off, descent, and the phases that follow. The items captured here belong to the opening of that sequence: the power-up and pre-flight stage that must be settled before departure clearance, engine start, and take-off are reached. Carrying this checklist through a flight keeps a consistent record of the aircraft's state at the point where the flight begins.
