Getting information into glass panels-or even a basic GPS navigator-can be a frustrating exercise in knob-twisting and button-pushing, as the first photo, below, of an Aspen PFD, exemplifies. Thankfully, even personal-airplane avionics are growing up and emulating larger aircraft.rnThe second photo is of a Cirrus equipped with Garmin's Perspective system and features a full keyboard. An increasing number of personal aircraft designers are finding some extra space to fit keyboards, and eliminate much of the knob-twisting, although no one should expect knobs to go away completely.
