Thanks Bruce.I received your correspondance in Saturday's post. Interesting proceedure.A bit of a convoluted way of achieving the same answer we seek today using other methods.It just reinforces what you wrote last week about using today's methodologies to explain yesterdays. After viewing what Bruce sent me I got out my old nav books and just started to look through them and was suprised at just the change in nomenclature or labels to define some event or proceedure.I'm compiling a list of changes (1st of just terminology and 2nd of proceedure) and it may suprise quite a few of us on this list. Here's 2 that I've found are used in more then 1 old book(pre WW II prints).They may describe the same event today but are totally differant from the terminology we use today.I found I had to do some digging through these old books to find the meanings of the terms before going forward to figure out what the authors were trying to show me. 1. "G.C.T. and date" 2. "T.C.A. of observation"
