Back in the days of steam gauges and conventional VHF nav, you could jump into any aircraft and feel comfortable because everything always worked the same way. It was simple.
But in the age of satellite navigation, electronic instrumentation and multi-function displays with moving maps, each aircraft is different. Just because you can fly an Avidyne Integra-equipped Cirrus doesn’t mean you can jump into a Perspective (a.k.a. Garmin G1000) Cirrus. Or, for that matter, even an old steam-gauge Piper. Now we need proficiency not just on an instrument scan and IFR procedures, but on the installed devices as well.
