photo landing on SeeYou 3.95

Yep - I had exactly the same problem when a gear door stuck open.
"Pure glider" didn't fix it either, as the noise was loud *throughout
the flight, but this should work for an isolated noise spike. *I was
able to modify mine *by changing the start and end of soaring times.

Why is that people cannot design software to ignore the ENL record
when the glider is not a motor glider? I am often irritated by having
to adjust my start time on OLC because it uses the noise level even
though I am not a motor glider.

When I asked OLC for ENL to be ignored I was asked "how shall we
determine your start of soaring flight". I responded "same as for
logs that have no ENL record". Nothing changed, it still uses ENL for
pure gliders.

OLC may use noise level to help determine when you are on tow.

On SeeYou, the noise level on my flights drops noticably when I retract
the gear, as you would expect. However, it also drops when I get off
tow. I suspect that the recorder can pick up the noise of the towplane.
Or the slower speed off tow reduces wind noise, though the noise level
on tow still is noticably higher than on a final glide flown at towing
speed.

I am looking at my most recent flight. When I got off tow, the noise
went from 60 to 40 on the y axis of the SeeYou noise graph (it went from
250 to 60 when I retracted the gear).

I checked my last flight, too. It's from my LS8.

When I select "Engine Noise Level" in SeeYou V3.95 all that appears to
be shown is a green trace. Close inspection of the barograph trace
under high zoom does show a 4 second red dash and a 4 second yellow
dash when the tow plane revs up and a 16 second red dash during
landing roll out on grass. The tow portion of the trace may have a
slightly yellower color, but it's really hard to say.

However, when I select "GPS Status" I see a purple trace (which SeeYou
labels "Engine/Tow") during the period I was on tow, another purple
trace during the period I was thermalling with my gear down (during a
low save), but a green trace during the period my gear was down and
the spoilers were out just prior to landing. There is no level shown
in "GPS Status" - just "GPS Bad", "Engine/Tow", GPS OK", "Circ. Left
and "Circ. Right".

Seems to be curious behavior, especially if OLC is counting on it for
scoring. It's unclear whether it's due to SeeYou or my Volkslogger.

Bring up the graph of altitudes in SeeYou, and click on "engine noise
level." It will plot sound on a graph. Much easier to read.

Thanks, Greg. I got to the plot by using View|Graph|Engine Noise
Level. It is certainly easier to read, but it brings up a new
question.

On tow I have an average noise level of 200. Off tow the noise level
goes to 30. Then I lowered the gear, and the noise level rose to 100.
The tow and the gear lowered sections are colored purple (meaning
Engine/Tow) if you select "GPS Status" for coloring. This is all fine.
However, just prior to landing I lower the gear and starting using
spoilers. The average noise is now 150 - but this section is colored
green, not purple, if you select "GPS Status" for coloring.

Something is inconsistent.

I flew a TAT today at the Cordele, Ga USA contest, and as I always do
I opened my flight in SeeYou 3.95 for analysis. Except this time it
showed a 'photo landing' between the 2nd and 3rd turn areas, and there
seems to be no way to get rid of it. I have been using SeeYou for at
least 8 years, and am pretty familiar with the common sorts of task
declaration errors that can lead to this situation. However, this
time I can't get rid of it for the life of me.

I attempted to post this on the Naviter support forum, but that seems
to be screwed up too. I can't get an activation email, and since I
can't get an activation email, I can't complete the forum registration
and therefore can't post. I also looked at their forum postings about
'photo landings' and it seems that the SeeYou folks aren't really
interested in addressing this issue (assuming it *is* an issue and not
just something I'm doing wrong).

Anyone else had this problem with SeeYou 3.95?

Frank (TA)

Without a copy of the igc file I can't be sure, but if it was an AAT
(which
it looks like from the task description), I would guess that the photo
landing is when the time ran out (i.e. 2h30 from the start).

Posting to OLC was the right thing to do. As soon as I saw the trace,
I noticed that the ENL levels were spiking way up, even though I have
a pure glider. There happened to be a big spike at 2:06 that
coincided with a low point, and I guess the algorithm in SeeYou
decided that I had started the engine there. It would be nice if
'Photo Landing' were replaced with 'Engine Start' in this case - would
have avoid a lot of electron abuse ;-).

TA

Now that your trace has been posted where I can get at it, I've looked at
it.
I can't see any noise in SeeYou.
If you set the task time to 2:30, you get a photo outlanding after 2 hours
30 (no surprise there!),
If you set the task time to 3:30 you get a completed flight.
If you leave the tasktime at 00:00:00 it gives you a completed flight.

I ran it against a UK scoring script with a 2:30 task time and it scores you
just fine (3h25m38s, 154miles, 44.9 mph) although it still shows a photo
outlanding at the task timeout time (as it should).
I don't think SeeYou can create good results from an AAT without the help of
a scoring script, it's OK with Racing tasks without a script (simple
computation of distance vs time).

good luck with the comp!

Under what set of rules is a maximum task time ever set?

I am looking at my most recent flight. When I got off tow, the noise
went from 60 to 40 on the y axis of the SeeYou noise graph (it went from
250 to 60 when I retracted the gear).

Possibly SeeYou is using the descent rate to say - noise is high but I
am descending - that's OK. And conversely noise level high and ascending
(thermalling with the gear down etc. ) that looks like an engine?

Not sure - someone should ask Erazem or Andrej.

On any day that has a CIvil Twilight, for a start.

I don't know what they do if there are gliding contests north of a
line from Oslo to St Petersberg.
