Note: the unfortunate consequence of discussing these aviation subjects is that I try to stay somewhat superficial to keep the posts brief. If I appear to be incomplete - or worse, as if I don't know what I'm talking about - it is probably because getting any deeper into the weeds creates new tangents that I often try to follow through in subsequent entries. I just cannot include every possibility or scenario so I include links to references for you to do your own research. Thank you to those who respond to clarify my answers, sources, positions, etc. We all have opinions, knowledge and experiences to contribute to the "conversation." I write this blog to learn and share, and I hope the readers do as well.
