You are part of a flying club with two identical planes based at KHRF. (Pick any plane you’re familiar with that’s capable of mountain IFR.) Since you’re the only instrument-current pilot in the group, the club only needs one GPS data subscription. You usually just swap the cards between planes to make sure you have current data. Except that a club member just took the current data card on a cross-country trip, leaving you with two-year-old data. Fortunately, it’s 17012KT OVC100 10SM over your entire route tonight. Unfortunately, it’s night tonight. (It happens.)
