In the world of aviation, the Boeing 737 is a name that resonates with pilots and enthusiasts alike. As one of the most successful and widely used aircraft in history, the 737 has undergone numerous advancements and updates over the years to ensure it remains at the forefront of aviation technology. One such advancement is the Cruise – Flight Management Computer (FMC) page, often referred to as the CRZ page. In this article, we will explore what the Cruise – FMC page is and how it contributes to the overall operation of the Boeing 737.
The Cruise – FMC page is a vital component of the Flight Management Computer system found on the Boeing 737. It is specifically designed to assist pilots during the cruise phase of flight, which is the period of time between takeoff and landing when the aircraft is at its most stable altitude and speed. This page provides pilots with a range of critical information and functions to ensure smooth, efficient, and safe flight operations.
One of the key functions of the Cruise – FMC page is to display the aircraft’s current position and track. Using data from GPS, Inertial Navigation Systems (INS), and other sources, the FMC calculates the exact position of the aircraft and presents it on the page. This information enables pilots to accurately monitor their progress and ensure they remain on track.
Additionally, the Cruise – FMC page provides information on the aircraft’s current altitude, speed, and fuel consumption. Pilots can use this data to optimize the aircraft’s performance, ensuring it operates at the most fuel-efficient levels while maintaining a stable flight profile. Making adjustments based on this information can result in significant fuel savings, which not only reduces costs but also contributes to a greener and more sustainable aviation industry.

Features and Functions of the Cruise – FMC Page
The Cruise – FMC page offers a range of features and functions that enhance the pilot’s ability to monitor and control the aircraft during the cruise phase. Some of these features include:
1. Performance Calculations
The FMC on the Cruise page allows pilots to perform various performance calculations. These calculations include determining the optimal cruise altitude and speed for the given weight of the aircraft, as well as providing estimated fuel consumption based on the current flight conditions. By inputting data such as takeoff weight, outside air temperature, and wind speed, the FMC can generate these calculations, enabling pilots to make informed decisions for a more efficient flight.
The Cruise – FMC page also offers pilots an overview of the planned route and the ability to monitor its progress. Pilots can access detailed navigation information, including waypoints, airways, and distances to the next waypoint. This information allows them to verify that the aircraft is following the planned route accurately and make any necessary adjustments if deviations occur.
Furthermore, the FMC provides the option to display a moving map on the Cruise – FMC page. This map shows the aircraft’s position in relation to its planned route, as well as other significant waypoints and features. Pilots can use this visual representation to enhance situational awareness and ensure an accurate and smooth flight.
3. System Monitoring and Alarms
The Cruise – FMC page incorporates various monitoring functions to keep pilots informed about the status of critical aircraft systems. It provides real-time data on parameters such as engine performance, fuel balance, and system health. If any abnormalities or malfunctions are detected, the FMC will alert the pilots through visual and audio alarms, allowing them to take appropriate action promptly.
Moreover, the Cruise – FMC page provides important information related to the aircraft’s time of arrival at the destination. By taking into account the current groundspeed and the remaining distance, the FMC calculates the estimated time of arrival (ETA) and presents it on the page. This information helps pilots manage their flight schedules effectively and communicate accurate arrival times to air traffic control and ground personnel.
Conclusion
The Cruise – FMC page on the Boeing 737 is a powerful tool that contributes to the overall efficiency and safety of the aircraft during the cruise phase of flight. By providing pilots with essential information and functions, it enables them to optimize performance, monitor the route, and respond to any system abnormalities effectively. With its advanced capabilities and user-friendly interface, the Cruise – FMC page plays a critical role in maintaining the Boeing 737’s reputation as one of the most reliable and technologically advanced aircraft in the world.
