Contains switches for systems used during normal flight operations (e.g., fuel pumps, generators, hydraulic pumps, ECS/pressurization).
: Contains the primary system controls used during flight, such as Electrical, Fuel, Hydraulics, and Air Conditioning. Aft Overhead Panel
Positioned on the middle-left side, this panel ensures aerodynamic surfaces and sensors remain clear of ice.
For a comprehensive "deep write-up," these specific resources provide the circuit-level and operational details required:
The overhead panel in the 737-800 is split into two main sections:
To demonstrate the utility of these PDFs, here is a typical "Electrical Power Up" sequence from a standard 737-800 overhead panel checklist. This should give you an idea of how detailed these resources are:
provides an excellent overview of panel functions intended for educational and entertainment use. Structure of the 737-800 Overhead Panel The overhead area is divided into two primary sections: :

Transfers the electrical load to the Auxiliary Power Unit generator. 2. Fuel System Panel
Many 737 simulation manuals, such as the X-Plane Boeing 737-800 manual, contain clear, actionable diagrams of the overhead panel.
Connects external AC electricity to the aircraft when parked at an airport gate.
Follow the white lines (schematics) printed directly on the panel that show how fuel and air move through the ship. 4. Operational Tips for the 737-800 Overhead
When you search , Google might return 20-year-old files. Here is how to spot a bad one:
Essential for ensuring both "packs" (air conditioning units) receive air during engine start.
The overhead panel is where you find the system and the flight control shutoff valves. In modern NG models, these are simplified but require a strict "guards down" policy to prevent accidental disconnection of flight surfaces in mid-air. Pressurization and Air Conditioning
This section manages the AC and DC power distribution. Key components include generator controls for both engines, the APU (Auxiliary Power Unit) generator, and external power. 3. Fuel System
3.8 Oxygen Systems
Prevents fogging and ice on the cockpit windshields.
: Start the auxiliary unit to provide air (pneumatics) and electricity.
