during preflite i set CG to 18, so the box stops b#tching about "MAX LVL xy"
the TOC isa i leave blank. why? tried to do it perfect with temp for wpt nearest to TOC from fliteplan. didn't work. and it's dahes, not boxes.
with final loadsheet we set MAC@TO as CG. works fine. only very minor changes on CRZ page (opt/max) during climb due to fuel burn.
