Edit Comment Close By: sharm44 (35 month(s) ago) Hi there, i am navy pilot...I found that ur ppt is very sound and knowledegable. Simple and easy to understand the whole chapter of a VOR. I have to teach my junior pilots regarding VOR theory. Would u share ur ppt via email. Ur cooperation is very much appreciated. my email : mdsharm@yahoo.com Saving.....
