This is really a question that Throttleup should have posted:P ,but here goes.Coming in to land at a normal approach speed for the airplane, let's say 120 shows on the red bar.If I were to replay that landing or video it the speed shown on the red bar then is typically 15 to 20 knots slower!I find this odd...very odd indeed..:-roll Andy
