Manages backup AC/DC power via the static inverter and battery. Normal position is AUTO.
The overhead panel, also known as the overhead console or overhead panel assembly, is a critical component of the Boeing 737-800 flight deck. It is located above the main instrument panel and contains various switches, lights, and controls that are used to monitor and control the aircraft's systems. The overhead panel is divided into several sections, each of which is responsible for a specific system or function.
: The bottom section of the forward panel houses exterior light switches (Taxi, Landing, Strobe) and the APU Start Selector .
Look for panels that explicitly label the "normal" (Auto/On) position for each switch. Detailed Breakdown of Key Systems (P5 Panel) 1. The Electrical Power Panel boeing 737800 overhead panel pdf new
Directs high-pressure air from the engine compressors into the pneumatic manifold for anti-ice, starting, and air conditioning.
While the physical switches are vintage, modern iterations and retrofit 737-800s include: Digital Standby Instruments:
