Gotta love it when a person who has never flown a twin airplane of any kind, much less a twin Cessna, tells you that your landing are done wrong.
See, the Cessna twins, pretty much all of ’em, not just the 340’s, like a bit of power all the way to touchdown. Unlike many smaller airplanes, where you pull the throttle to idle as you pass over the numbers (or are at a point where the field is made), these airplanes (and lots of twins) land much more smoothly with a bit of power… not enough to keep flying, but just to smooth the rate of descent.. Not full stall landings like in a 172 .
Of course, some people are “experts” because they know what they were taught. Like cops who were told that the GLOCK is the greatest handgun, and therefore believe it to be true, some pilots only know what they know, and think that that applies to every other plane, even though they have never flown one except is Microsoft Flight Simulator (if that)
I don’t tell 737 pilots how to land those….I’ve never flown one, not even in a sim. I’m sure that is takes some additional skill and a different technique than my 340.
