![]() One of the problems with devices that clean so easily is that there’s a lot of reflectivity in those devices.” ![]() “For example, the best touchscreens are the ones where if you get a fingerprint on them you can wipe it off really easily. “The requirements that drive the viewability of the display and the requirements that allow for good touch in some cases are mutually exclusive,” said Sinnett. Sinnett explained that although no requirements exist that “drive” the use of the touchscreen, the challenge for engineers centers on simultaneously maintaining standards associated with image quality, chromaticity and off-axis viewing angles. Sinnett called touchscreens “a really great example of trying to understand what the requirements are and convey those requirements in a flight deck design.” But despite the seeming ubiquity of the technology in everyday computing devices, aerospace engineers still must consider technological hurdles specific to airplane design. However, Boeing continues to “define requirements” and expects to sign a contract with a supplier of the touchscreens later this summer. The 777X’s cockpit display provider, Rockwell Collins, worked with Boeing on the technology on the EcoDemonstrator. Test results from Boeing’s EcoDemonstrator program have convinced the company to feature touchscreen displays in the cockpit of the new 777X airliner, BCA vice president of product development Mike Sinnett revealed during a pre-Farnborough briefing on developing technologies at the company’s Seattle-area offices.
