Overview of the Boeing 737 Cockpit

The Boeing 737 cockpit is designed to be the operational hub where pilots control every

critical aspect of the flight. Over its multiple generations, from the original 737 Classic to

the Next Generation (NG) models and the latest MAX series, the cockpit has evolved

significantly. While the core layout remains familiar, each iteration introduces

enhancements in avionics, controls, and displays.

The cockpit is essentially divided into several key areas: the flight instruments, the control

panels, the overhead panel, the center pedestal, and seating arrangements for the

Captain and First Officer. This layout ensures that pilots have intuitive access to all

necessary functions, supporting situational awareness and reducing workload during all

phases of flight.

Flight Instruments and Primary Controls

At the heart of the Boeing 737 cockpit layout are the primary flight instruments. These

include the attitude indicator, airspeed indicator, altimeter, vertical speed indicator, and

heading indicators. On older 737 models, these were predominantly analog gauges, but

with the introduction of the NG and MAX series, the cockpit moved toward a glass cockpit

design featuring large LCD screens known as the Primary Flight Display (PFD) and the

Navigation Display (ND).

Primary Flight Display (PFD) and Navigation Display (ND)

The PFD consolidates crucial flight data in a single, easy-to-read screen. It shows pitch,

roll, airspeed, altitude, vertical speed, and heading in a digital format that enhances pilot

awareness. Adjacent to the PFD is the ND, which provides navigation information including

the flight path, waypoints, weather radar, and terrain mapping.

This dual-display setup is a massive improvement over older analog dials, reducing the

chance of misreading instruments and enabling quicker decision-making. The layout

places these screens directly in front of the pilots, minimizing eye movement and allowing

for quick cross-checks.

Control Columns and Throttle Quadrant

The control columns (yokes) in the Boeing 737 cockpit are centrally important. They allow

pilots to manually control the aircraft’s pitch and roll. The layout positions the Captain’s

yoke on the left and the First Officer’s yoke on the right, with easy access to control

buttons for autopilot disconnect, push-to-talk radios, and trim control.

Located between the two pilot seats is the throttle quadrant, which includes the throttles,

speed brake lever, and flap controls. The throttle levers control engine thrust and have

detents for various power settings like idle, climb, and takeoff. The speed brake lever

allows pilots to deploy spoilers to reduce lift and increase drag, particularly useful during

descent and landing.
