Safe aviation operations often hinge on the use of modern, digital technologies that improve the safety of flight operations, the efficiency of systems, and much more. Among the many forms of equipment and devices that have made their way on board current aircraft, the Electronic Flight Instrument System (EFIS) in particular has become a standard feature in civil and commercial design, having long replaced older analog dials with advanced digital displays. By integrating flight data into a cohesive, intuitive format, EFIS systems play a pivotal role in enhancing pilot awareness, reducing workloads and improving decision-making for the benefit of pilots.
In this blog, we will explore what EFIS technology is, covering everything from basic design elements to how such systems support pilots in maintaining safe and efficient flight operations.
In its most basic form, an EFIS is a computerized display system that presents critical flight information to pilots through digital screens. Typically featuring liquid crystal displays (LCDs) or even cathode ray tubes (CRTs) in earlier generations, an EFIS is essential for achieving a more versatile and adaptable interface when compared to traditional options.
Unlike analog instruments that are only capable of showing individual pieces of information per gauge, an EFIS consolidates multiple data sources into integrated displays, offering pilots a more holistic overview of an aircraft’s operational status. This digital approach also saves cockpit space while reducing the amount of work pilots need to undertake to maintain optimal situational awareness.
While an EFIS may vary in exact design depending on the needs of a particular aircraft, most will typically comprise three primary display types, each of which has a distinct function or importance.
The PFD is an essential element of modern glass cockpits, providing pilots with a simplified means of digesting important flight data, including:
The PFD tends to integrate information from the attitude and heading reference system (AHRS) and air data computer (ADC), ensuring the most accurate data for flight use.
With an ND, pilots can obtain important navigational information, such as:
These forms of information serve to enhance pilot planning capabilities by displaying the present position data and future trajectory details.
An EICAS can be used to display engine parameters, including thrust, temperature, and fuel flow information. This technology also provides alerts for system malfunctions and required crew actions, simplifying monitoring tasks with integrated color-coded warnings and other features.
An EFIS operates by receiving raw data from various aircraft sensors and avionics systems, processing and displaying this received information in an intuitive format for pilots. Generally speaking, the main sources of data for an EFIS include the following:
The consolidated displays provided by an EFIS allow pilots to view multiple parameters simultaneously. By integrating terrain and weather relays, crews are also highlighted to potential hazards that are in their path. These displays also offer clear symbology, ensuring there is a reduced risk of misreading critical data.
Enhanced situation awareness through the real-time integration of navigation, weather, and traffic data provides pilots with comprehensive information that improves their ability for decision-making. For example, pilots can better anticipate and respond to potential issues more effectively with simplified prioritization of issues and clear conveyance of data.
Automatic alerts and warnings minimize the need for pilots to conduct constant manual scanning, while flight data organization reduces the number of separate instruments to monitor as well. This in turn streamlines cockpit operations, particularly benefiting pilots during high-stress phases of flight.
Consistent, standardized displays across aircraft models minimize training requirements and confusion, allowing pilots to quickly identify anomalies and carry out corrective actions. Efficient data presentation also supports smoother coordination between cockpit crew members.
Pilots leverage EFIS systems across all phases of flight, with important benefits being derived during each step from takeoff to landing.
