Continuing on our series 'Flying info and tips', we delve into the command center of any airplane - the cockpit. As I learned during my days building flight simulators, it's an organized maze of controls, switches, displays, and dials. Read on as Capt Stephens delves into the particulars of the terms and functions of all the major systems in a commercial aircraft. If you want to learn step-by-step from a pilot's perspective what happens from pushback at departure to parking at the gate, here is a great in-depth article.
As a seasoned pilot, the cockpit is where I spend a significant portion of my life. This space, filled with intricate controls and displays, is the heart of an aircraft. While passengers usually only hear from us during takeoff, landing, or when turbulence hits, there's always something happening behind that closed door.
What is the Cockpit?
The cockpit, or flight deck, is where we pilots, both the captain and co-pilot, manage the entire flight. This includes communication with air traffic control, navigation, and control of the aircraft's engines and systems. From my experience, it's crucial to have all the necessary information and controls at our fingertips to ensure a smooth and safe journey.
What does Plane Cockpit mean?
Think of the cockpit as our office. It's where we receive all the essential data through various panels and instruments. I remember my first flight, being amazed at how much information flows through this confined space. Everything we need to keep the plane stable and on course is right here. The cockpit's design and layout are essential for efficiency and safety, making it possible to manage the aircraft effectively.

What does the cockpit team consist of?
Typically, the cockpit crew consists of two pilots: the captain (often me) and the first officer. The captain, who usually sits on the left side, is responsible for the overall operation of the flight. I remember flying with many talented first officers who assist with various tasks, from handling radio communications to helping with navigation. In the old days, a flight engineer was also part of the team, but modern technology has automated much of that role.
Cockpit procedures before taking off
Before we even think about taking off, several procedures must be meticulously followed:
- Flight Details Review: As the captain, I go through every detail of the flight, from the destination to the weather forecast. It's vital to know the aircraft's weight, the number of passengers, and the crew on board. This preparation is crucial; I've seen how it helps prevent issues later on.
- Aircraft Inspection: The first officer performs a walk-around inspection to ensure everything looks good. I've had times where this inspection caught minor issues that could have become significant problems.
- Instrument Check: We both verify that all control and flight instruments are functioning correctly. There was a flight where an instrument malfunctioned, and because we caught it early, we could address it before departure.
- Flight Release Document: I sign off on this document, confirming that I'm aware of all flight details and that the crew is ready to go. It's a final check to ensure everything is set.
- Clearance: We then wait for clearance from air traffic control to start our journey.
Cockpit Components
The cockpit is packed with various systems and instruments that we've become very familiar with:
Overhead Panel
This panel, situated above our heads, monitors the aircraft's systems like electrical, hydraulic, and fuel. It's fascinating to see how these systems work together to keep the aircraft in optimal condition.
Instrument Panel
In front of us, this panel includes the flight management system, which holds the flight plan and speed control. The autopilot controls are also here, just below the windscreen. I remember the first time I engaged autopilot; it felt like magic!
Flight Control Unit
This unit displays critical data like altitude, heading, and rate of climb/descent. Whether using a traditional yoke or a fly-by-wire joystick, these controls are essential for steering the aircraft.
Other Control Systems
Additional systems provide information on wind speed, fuel temperature, and cockpit pressure. We also have backup instruments, a safety feature I've always appreciated, especially during unexpected situations.
Glass Cockpits
Many modern aircraft, including those I've flown, feature glass cockpits. These systems replace traditional dials and switches with high-resolution displays. The benefits are immense:
- Enhanced Communication: Radios and other systems make it easier to stay in touch with air traffic control.
- Precision: Digital displays provide exact numbers for altitude, speed, and other vital data, reducing guesswork.
- Graphical Weather: Digital weather updates are a game-changer, providing real-time information that helps us navigate around storms.
- GPS Navigation: Modern GPS systems assist us in planning routes and estimating arrival times. It's a far cry from the old days of manual calculations.
- On-Screen Checklists: Having digital checklists speeds up procedures, ensuring we don't miss any steps.
- Faster Interpretation: The clarity of digital displays allows for quick data assessment, which is crucial during high-pressure situations.
