Anyone wondering what on earth this about, here is the description which for
reasons I won't bore you with, got lost in transmission to the net.

Attached is a program (42k) which might be of interest to those of you who
are able/willing to download your gps track files into the pc. Originally
written to convert from NMEA to Jeppesen Flitestar track format, it has some
extras for use even if you do not use the latter. The main one I find useful
is that it extracts your airborne times (between stall speeds) so that you
can fill up your logbook at leisure without having to scrabble around for the
bits of paper on which you may (or may not) have recorded them, or peer at
the code to guess when you actually lifted off ( if you stall during flight,
that's tough (:-)), assuming you recover you will get two flights for the
price of one ). It also lists the speeds and headings, but as gps readings
are only nominally at fixed (e.g. 30 sec) intervals these may not be all that
useful for calibration unless you keep a constant speed for several
intervals. A typical screen output is:

Trkop.exe has been included in the zip and is a version without the Jeppersen
