so yeah all that sounds good.
actually i do it the way higney said. i will climb at 290 till it hits .70. then i will just press the center of the speed bug and put it at a climb of .70. sure the mach moves down as we go higher, but you will keep a fairly constant 700-1000ftpm climb as you do it all the way to cruise. it works great and keeps you from having to just put 500vs in and watch your plane lose all of its energy. ah but alas the "energy" discussion is a different topic!
