Boeing 737-800 Cold And Dark Startup Pdf
Boeing 737-800 is a popular commercial jetliner that has been in service since 1998. With its advanced technology and high performance, it has become a favorite among pilots and airlines alike. If you want to learn how to start up a Boeing 737-800, you will need to know the steps for the "cold and dark" startup procedure.
In this article, we will provide you with a comprehensive guide on how to do a "cold and dark" startup of a Boeing 737-800 with a focus on the PDF checklist. We will cover all the necessary steps that you need to know to safely and efficiently start up the aircraft.
What Is The Boeing 737-800 Cold And Dark Startup Procedure?
Before we dive into the details of the procedure, it is important to understand what "cold and dark" means. When an aircraft is in a "cold and dark" state, it means that all the electrical systems and engines are shut off, and the aircraft is not receiving any power from an external source. In this state, the cockpit displays are all dark, and there are no sounds or movements coming from the aircraft.
The "cold and dark" startup procedure is the process of starting up the engines and electrical systems of the aircraft from this state. It involves following a set of procedures and checklists in a specific order to ensure that the aircraft is safely and efficiently started up.
Step-By-Step Guide For Boeing 737-800 Cold And Dark Startup Procedure
Here are the steps for the Boeing 737-800 cold and dark startup procedure.
Step 1 - Battery Power On
The first step in the procedure is to turn on the battery power. This is done by turning on the battery switch, which is located on the overhead panel. This will provide power to the essential electrical systems of the aircraft.
Step 2 - External Power On
Next, we need to turn on the external power. This is done by plugging in the external power source and turning on the external power switch. This will provide power to the rest of the electrical systems of the aircraft.
Step 3 - APU Start
Now we are ready to start up the APU. The APU, or auxiliary power unit, is a small gas turbine engine that provides power to the electrical systems and air conditioning of the aircraft. To start up the APU, we need to turn on the APU switch, located on the overhead panel, and follow the APU start procedure outlined in the checklist.
Step 4 - Hydraulic And Fuel Pumps On
Once the APU is started, we need to turn on the hydraulic and fuel pumps. The hydraulic pumps provide hydraulic pressure for the aircraft's control systems, while the fuel pumps provide fuel to the engines. The switches for these pumps are located on the overhead panel.
Step 5 - Engine Start
Now it's time to start up the engines. We need to follow the engine start procedure outlined in the checklist to safely and efficiently start up each engine. This involves turning on the engine start switches, monitoring the engine parameters, and adjusting the engine controls as needed.
Step 6 - Taxi And Takeoff
Once the engines are started and all the systems are operational, we can begin taxiing to the runway for takeoff. We need to follow the taxi and takeoff procedures outlined in the checklist to ensure a safe and efficient departure.
Conclusion
The Boeing 737-800 cold and dark startup procedure is an essential process that every pilot needs to know. By following the steps outlined in this article and using the PDF checklist, you can safely and efficiently start up the aircraft and prepare it for takeoff.
