The technical innovation outlined in this paper describes the efficiency and benefit of displaying and updating critical radio tuning frequencies that the crew relies on during flight. These frequencies can be set using single fingered ‘swipe’ gestures directly on the display’s top layer page without having to enter into numerous sub layer pages. Top layer pages such as the Primary Flight Display (PFD) often obtain a considerable amount of attention on the flight deck, thus making it an ideal candidate for this feature. This intuitive and efficient user interface enhances crew and would require little to no additional training.

Outside of avionics, touch screen gestures have been used for various devices for a number of years. Numerous studies [1, 2] concur that single fingered gestures allow for improved accuracy and efficiency in comparison to complex gestures or even mouse-based interactions.


On modern aircraft, the crew often has numerous windows displaying different information at various points in the flight. From the display, the current practice forces the crew to navigate the HOME menu, then to the TUNING page, and lastly enter into its preset submenus to tune the Very High Frequency (VHF or COM) or High Frequency (HF) radios. Typically, the presets are loaded prior to execution of the flight, thus making the TUNING menu navigation not only tedious but also unnecessary.

At a minimum, COM radios are displayed on the Primary Flight Display(PFD) for first and second instance radios. This solution involves the use of a single fingered 'swipe' gesture to rotate the active radio frequency between the recall frequency, preset 1, present 2, …, present 20, back again to recall. To set a swiped frequency as active, the crew will validate the entry by a single tap (or downward swipe) on the frequency; whereas a selection (tap) off of the frequency (or an expired timer) would effectively cancel the operation. This allows the crew to tune a preset directly on the PFD. More importantly, this innovation allows the crew to directly tune to a preset frequency without having to take their eyes off the display.

Technical Discussion

Touch screen technology that activates a confirmation upon the release of the pressure point. The touchscreen controller determine the validity of touch screen interaction into an identifiable 'swipe' gesture.

Due to the popularity of smartphones and tablet computing, using simplified gestures is preferable in today's environment. These simplified gestures underscore the importance of a "no training required" interface that customer...
