In this photo of my former Bonanzas panel, top, you can see it includes analog instruments along with VOR- and ADF-based nav systems, and a lone portable GPS on the yoke. Most of it operated intuitively and without the need to navigate various sub-menus. Even the airplanes sophisticated-for-its-day Century IV autopilot with yaw damper is relatively simple to operate.
The author contrasts the intuitive operation of older analog aircraft panels with modern, menu-driven GPS systems.
Modern GPS units, such as the Garmin 430, are capable but demand significant time and frequent use to achieve and maintain proficiency with their complex interfaces.
Maintaining proficiency with advanced avionics is particularly challenging when flying multiple aircraft models infrequently.
