Is it common for airline pilots to lose their SEP?
I know it takes some time untill it expires. Also we're talking about the land of EASA, i don't know how it works in the US.
But for someone who only files airliners for a living, which obviously aren't single engine piston aircraft, it can be easy to forget.
If you're an airline pilot, who has a couple years of large jet expirence, have you let your SEP expire?
