Don't get mad at me, but I agree with you 100%. There are a lot of other factors related to a particular plane being able to KE, I was just trying to mention the BASICS, so he could develop a better understanding of where to start. I have never seen a Harrier fly, I have no idea what it is capable of. I have been involved in other situations as the student while learning myself, or as the instructor trying to trim out a trainer for another guy, and going back to the basics can really make a big difference. If someone tells me he has been through the entire trim chart sequence and can't get the plane to KE, I will tend to believe him more than someone who claims a plane won't KE at all. I think I remember reading a magazine review that said the plane does great KE, but I can't remember for sure. There are rules that make every plane fly. Tweeking them to get your plane to do what you want is the hard part.
