or something else?
Heh, instructor hat on with hat one, am I right Mace? I'll bite, to me it's obvious that the other things you mentioned aren't the "real" answer to that question, and I really want to know what it is. I'm usually near the deck in my fights too, and I typically go with exactly what Latrobe described, using landmarks and the distance between them to judge the NME E state. That only works for me however if he's flying in the horizontal, giving me the opportunity to observe his velocity/time between two fixed landmark points.
How do you do it if he's vertical somewhat? I know there is the obvious answer of his nose being up = burning E, and nose low = gaining E, but I sense you have an answer to that posed question that is a little more complex and accurate, n'est pas? I know you can observe the con distance icon, and the - or + is an indicator of the NME E relative to my E, but that still doesn't answer to what his E precisely is, to me it's still just a relative value to my aircraft. Is it just something that comes with experience once you start considering this stuff? I know I can look at my airspeed/altitude/situation and try and form some kind of solution based on the 2 ways I use that I mention, landmark and con +/-, but I still feel like I'm missing something.
This is something I really struggle with, judging E state, and to me, all this great information regarding ACM can only be put into practice once you CAN judge the NME E state, otherwise you're just skating uphill IMO. It feels a little (a lot) like I'm trying to run before I can walk I guess with this specifically.
