Not long ago I was on a flight during which we were setting up to fly an ILS approach at South Bend, IN (KSBN). The aircraft had a glass panel, a G1000 to be specific, and the approach was programmed into the system after selecting the airport and approach we desired.
But things weren’t going quite as they should normally.
There were hints to this effect however. Hints that a good instrument pilot or CFI-I should be taking into their scan and would cause them to ask some questions, namely, what the heck is wrong and am I going to be even able to continue this approach.
