Re: OLC, ENL, Start of soaring flight

Andy,

I have the same problem (ASW-27 CAI-302).  I used to think it was one of the
vents, but now I am not so sure because I open and close the nose vent and
side vents frequently, but only get the ENL at the beginning of the flight.
I remember submitting a flight to OLC one time and it “started soaring
flight” 250 KM down my first leg at 17,800 MSL!!    The problem was ENL.   I
simply deleted the flight and re-entered it using the manual adjustment for
the start time.  Since then, I do the following  for each OLC submission:

1.  Load the IGC file in SEEYOU and zoom in on the map to the release point
and get the precise release time and altitude per the flight log.  

2.  Check the “pure glider” box in SEEYOU (Edit, drop-down box “flight
properties”).  Then I hit control-L to have SEEYOU score the flight (I use
the classic distance).

3.  Upload the IGC file to OLC via “direct claim”.   Check OLC’s
determination of the start time on the second window and make sure it matches
the correct start time determined in step 1 above.  If not, correct it in the
box provided by OLC on that window then hit submit.

4.  After OLC scores the flight, I check to make sure the classic distance is
approximately the same (within 1 or 2 KM).  

I have not seen a “pure glider” box in any of the OLC web pages.  That would
make life much simpler.  Also, most glider models are either “pure gliders”
or “motorgliders”.  Since we enter the glider model during submission, it
seems like it would be easy to have the OLC software ignore ENL for those
models that are only pure gliders.

I'd like to hear from people who submit logs to OLC using a recorder
that has no  ENL (Engine Noise Level) capability and produces a log
with no ENL data.

Does OLC automatically determine the start of soaring flight, or do
you always have to set it manually? If OLC does it automatically, how
often does it get tow release point correct (close enough that you
don't have to revise the time to get credit for full flight distance)?

Reason for the question is that I fly a pure glider and quite often my
tow release is many miles in error as my ENL is high due to open nose
vent. (CAI 302, ASW28)

thanks
