<p><span>The FAA is accepting comments through September 24 on a draft update to its human factors guidance for flightdeck system controls advisory circular (AC), which would replace 15-year-old&nbsp;AC 20-175. Draft AC 20-175A retains the original’s scope of cursor control devices, touchscreens, speech recognition, and dedicated switches and knobs, while adding guidance for aircraft designs and cockpit technologies that have emerged since 2011. The most notable addition addresses “emerging aircraft,” including powered-lift and eVTOL designs. The FAA writes that these aircraft “often possess unique designs, flight, and handling characteristics” but that the human factors principles in the rest of the AC “are also applicable to the flightdeck controls” of these aircraft.</span></p>
