What Is an Electronic Flight Display (EFD)?

The aviation industry has witnessed remarkable advancements in technology over the years, revolutionizing the way pilots interact with flight instruments to safely operate aircraft. One such innovation that has significantly transformed the cockpit and its design is the Electronic Flight Display (EFD). With its sophisticated capabilities and intuitive use, the EFD has become an indispensable tool for pilots worldwide.

An Electronic Flight Display, often simply referred to as an EFD, is a modern electronic representation of the traditional flight instruments found in an aircraft cockpit. It replaces the conventional analog gauges spread across the dashboard with a digital screen containing all relevant instrument information. These displays offer numerous advantages over conventional gauges, including improved readability, flexibility, and integration with other aircraft systems.

A typical EFD will comprise various components that provide pilots with essential flight information. The primary flight display (PFD) is the central element, presenting crucial data that is sourced from the attitude indicator, airspeed indicator, altitude indicator, and vertical speed indicator. The attitude indicator displays the aircraft's pitch and roll, enabling pilots to maintain a steady flight path. Meanwhile, the airspeed indicator provides readings on the aircraft's speed relative to the air it is moving through, while the altitude indicator indicates the aircraft's current altitude above sea level. Lastly, the vertical speed indicator provides information on the aircraft's rate of climb or descent.

In addition to the PFD, the EFD incorporates other key flight instruments and technologies. The turn indicator is an instrument that helps pilots maintain a desired bank angle during turns, and the EFD displays the rate of turn digitally to ensure the aircraft remains coordinated throughout maneuvers, often providing visuals. Moreover, the heading indicator indicates the aircraft's current heading or direction of flight, and by constantly monitoring such data, pilots can maintain a desired course while making accurate navigation decisions.

When activated, the EFD relies on a data computer to gather information from various sensors and avionics systems on the aircraft for details to be displayed on screens. These sensors measure factors such as air pressure, temperature, and position. The data computer then processes this information and presents it in a user-friendly format on the display. This integration of data ensures that pilots have accurate and up-to-date flight information at their fingertips at all times.

One of the primary advantages of the EFD is its flexibility and adaptability. Unlike traditional analog instruments, the EFD allows for customization of displayed information. As such, pilots can choose to view additional data such as engine parameters, navigation aids, weather information, or traffic alerts. Additionally, they can customize data so that what is most important is always readily accessible without having to scan through various gauges. This versatility enables pilots to tailor the display to their specific needs and preferences, enhancing situational awareness and overall flight safety.

Furthermore, the EFD offers enhanced reliability compared to its analog counterparts. Traditional flight instruments are prone to mechanical failures, calibration issues, and wear over time. In contrast, the EFD's digital nature reduces the likelihood of such problems. Moreover, it can provide self-monitoring capabilities, alerting pilots to any potential malfunctions or discrepancies in the system. Nevertheless, the EFD relies on a power source for functionality, though many aircraft have backup analog gauges or power sources to guarantee that data remains available despite issues.

The Electronic Flight Display represents a significant milestone in the evolution of cockpit technology, and its user-friendly interface, customizable features, and accurate presentation of flight data have transformed the way pilots interact with their aircraft's instruments.
