The Remarkable HMIs of Futuristic Cockpit Designs

To get an idea of what futuristic cockpit designs will look like, just take a peek at the digital dashboards of today’s most advanced automobiles.

In place of the physical dials, gauges and push buttons there are sleek video screens that display more information than previously possible.

Speed in miles- or kilometers-per-hour might be displayed in large numerals instead of a needle position on a gauge. A powertrain schematic might show how the gasoline-powered engine is recharging the batteries of a hybrid vehicle. And the infotainment system might have a touch screen that can switch the satellite radio station.

Similarly, the cockpit of the future will substitute analog elements for digital ones, resulting in a cleaner aesthetic that utilizes a human-machine interface (HMI) of touchscreens, colorful interactors and indicators. The technology will also generate more data for the airlines and employ more automation for consistent flights.

Aircraft OEMs need to provide the safest and best experience for airline pilots. In the face of rising competition for aircraft purchases and the need to lower the costs to train pilots, updating the cockpit could be one of the best solutions.

It is now up to engineers and HMI specialists to ensure that any new design meets usability, access, safety and reliability standards so pilots can fly aircraft with less effort than ever. For instance, they will need to ensure the system avoids cognitive overloads and mode confusion — when the pilot might need to overrule the automation. To optimize the cockpit to these considerations, the specialists need to test it with pilots at various levels of expertise.

What Challenges Do Cockpit Designers Face?

Similar to a dashboard, redesigned cockpits must be optimized for smooth pilot interaction, while avoiding information overload.

However, the design is more complex, with more information and controls than a car’s digital dashboard.

Critical questions that arise when designing futuristic cockpits include:

  • Will the design meet certification and safety standards?
  • Are the most frequently used controls placed conveniently?
  • How to avoid mode confusion (where the aircraft’s assessments are out of sync with the pilot)?
  • Are multitouch screens convenient to use during turbulence and critical scenarios?
  • Are the layout, interactors and indicators designed to operate within the pilot’s cognitive threshold?
  • Is it simple for pilots to access the most crucial controls in the event of an emergency?
  • Are mission-critical messages and alerts easily available and understandable for pilots?
  • Can pilots easily view the right level of information during a flight in all weather conditions?

How Can Simulation Be Used Effectively in Cockpit Design?

Building physical prototypes of potential cockpit configurations, for human testing, is a time-consuming and expensive task. These prototypes are often built at the end of the design cycle where problems are complex and costly to fix.

Simulation can reduce the time and costs by automatically generating certified code for aircraft controls and by offering a virtual environment for prototype and safety testing. The code and simulation can also be easily reconfigured when components need to be relocated or modified for accessibility.

As result, these virtual prototypes can be created early in the development cycle so engineers can discover and fix issues when it is cost effective to do so.

Building the virtual prototype starts with a code generator. It automatically compiles embedded controls and HMI codes that meet aircraft certification standards. The code generation is more reliable than human-written code — an important consideration for safety-critical applications. Ansys SCADE and Ansys SCADE Display solutions are the best options for aerospace engineers interested in embedded code generation.

From there, a pair of virtual reality (VR) googles can turn any space into a virtual cockpit. The engineer needs to import the cockpit geometry and then define the location of instruments, controls, displays and interactors. Then by looking into the goggles, the pilot can see the instruments and controls —they can even interact with them as if they were real components. The pilot can then make judgments as to:

  • The placement of readouts and interactors
  • The visibility of outputs when the sun’s glare falls upon instrument panels
  • The amount of information that is calling for their attention at once
