Thanks, but...I think the problem is ICAO step size, it should be 4000 above FL290.So, where I fly or how long I fly is not the key point.When I choose flying at FL360, it shall be a step climb hint to FL400, if there is a s/c point when I fly far enough.if I fly at FL340, it shall remind me to step climb to FL380, FL330 s/c to FL370, ETC. But whatever altitude I choose (below FL360 for 1000nm flight), it just reminds me to step climb at FL390. Sorry for my poor English, but I didn't meet it on LDS767.
