Yeah, going from a Cessna to a Piper single, it is easy to forget switching tanks........that switching tanks every 30 - 60 mins is a stupid idea of Pipers. Cessnas ' both ' switch is so much safer.
( I know......if you only fly a PA28 you get used to it, l fly both (and twins) and it still sometimes ' gets me '.............
comeon Piper, spend a few bucks more and add a both position (or is there an STC for that ) ?
