1. Check the fuel tanks to verify they are filled with the correct type and amount of fuel.
Before starting up a Boeing 737-800, it is essential to check the fuel tanks to ensure that they are filled with the correct type of fuel for the aircraft. The pilot should also take time to determine whether the amount of fuel present in the tanks is sufficient for the planned flight.
2. Inspect all external lighting systems, including landing lights, navigation lights and strobes.
To ensure visibility during takeoff, pilots should inspect all external lighting systems on the Boeing 737-800. This includes inspection of the landing light system to make sure that it is functioning properly and that the correct position of its beams is set according to aircraft regulations. Pilots also have to check if other navigational and anti-collision lights are operational, as well as any emergency or distress signal beacons (strobes).
3. Verify that all system circuit breakers are in the proper position for startup operations.
Prior to starting up a Boeing 737-800, it is essential to check the system circuit breakers to ensure that they are in the proper position for startup operations. If any of these breakers are incorrectly set, it could lead to a malfunction or failure.
4. Determine engine settings using pre-checklist information or aircraft flight manual recommendations.
When preparing for a cold and dark startup of a Boeing 737-800, pilots must determine the engine settings according to their own pre-start checklist, or based on aircraft flight manual recommendations. This includes setting idle speed, fuel flow rates, mixture control and other engine parameters.
5. Ensure control surfaces, such as ailerons, rudder and elevators are properly positioned before starting engines.
To ensure the safe operation of the aircraft, the pilot must take time to check that all of the control surfaces on a Boeing 737-800 are in their correct positions before starting up the engines. This includes ensuring that the ailerons, rudder and elevators are properly positioned.
6. Test pressure pumps on both hydraulic systems; check fluid levels if applicable.
To ensure proper operation of the aircraft’s hydraulic systems, pilots should test pressure pumps on both systems prior to engine startup. They should also take time to check for any discrepancies in fluid levels and replace fluids as necessary.
7. Activate APU (auxiliary power unit) prior to starting engines; allow sufficient time for temperature stabilization before attempting startup.
Prior to beginning the engine startup procedure on a Boeing 737-800, pilots should activate the auxiliary power unit (APU). This will provide power to the aircraft’s systems in order to make starting up more efficient. Pilots must also be sure to allow sufficient time for temperature stabilization before attempting engine startup.
8. Check fire detection systems to ensure no false alarms occur during the startup sequence.
When beginning an engine startup of a Boeing 737-800, it is essential that pilots check their fire detection systems to ensure that there are no false alarms occurring during the startup sequence. This will help prevent any unnecessary interruptions or delays in the flight.
9. Verify that the main battery is operational by checking voltage levels and amperage.
To ensure that the aircraft's electrical system is functioning correctly, pilots must take time to verify that the main battery is operational. This can be done by checking voltage levels and amperage, in order to determine if the battery is providing sufficient power for startup operations.
