I would recommend the following method :Take a 3-view, at best with
given dimensions and then you can calculate for yourself, if length is
with or without the pitot. Bonus point of this method : You can easily
decide, if it is a good or a bad 3-view. ;D
I've done this for the first 3-view of the T-38, I've found on my HD and
taken the very first data, too : length 14.10m, span 7.7m .As span should
be unaffected by the pitot, I've got .. (see sketch below) :
But with the use of more than one 3-view and more than one set of data,
it should be possible to determine the correct dimensions, I think.
Another attempt, this time with a 3-view from an old Air World International
issue abd using the given scale ... hm, the calculated span don't match the
given data for the F-5, but I noticed, that very often it isn't mentioned, if
span is with or without tiptanks ! :
Never believe in 3-views, you didn't manipulate yourself !
