Hello friends!
I was already thinking that I was doing something wrong because VNAV really, if there is no interference from the pilot, it is not going well. Jan I am a big fan of CARGO and a variant of IXEG will be very welcome. I like the most classic aircraft like the 727, 737-200 and 737-300, 400 and 500. The NG family is cool, but it doesn't have the charm of a serious classic. The 737-200 is one of my favorites and here in my country, Brazil, it had an affectionate nickname of BREGUINHA something like "Tasteless" in English, that is, something out of fashion. This happened because when the 737-300 arrived, the pilots called it CHIQUE, something like FANCY in English (inside the fashion).
Sorry for my bad English, but I used the google translator to help.
