Re: Crash at Quebec Airport

In the news vids one can see one of the separated engines, very near the small crash site, and notice that the prop has an extremely fine pitch and only one blade of the 3 is considerably damaged. One witness said he heard one loud explosion (sounded like lightning) and then later a 2nd explosion. I...

Re: Eurostar suspends services for third day

The cause of the failures has been traced to small very particles of "dry" snow being injested into the traction motor cooling fans resulting in electrical short circuits when moisture developed on the warm motors. The normal air filters were not effective against this type of snow. While not a com...

Re: Is raising the minimum rage a good idea?

I find it very disconcerting, that before Sept 2008, the big US military complex didn't seem to have advised Bush2, at all, about the upcoming world economic collapse !??????

They could at least watch utube and do a search for Peter Schiff, "Dr Doom", or other.

Re: Small helicopter crash - 2 died...

I suspect they had a fuel line partial break considering the reported sputtering engine and quick and massive post crash fire.

The dead CTV cameraman was the son of very well known retired senior CTV anchor man.

Re: Is raising the minimum rage a good idea?

Forgot to add the 2nd sentence. Here they are again.

From latest GDP numbers. Today's GDP vs 1929's.

At the current rate we have 46% of a 1929 type depression.

From the data from the preliminary report here is a compilation of AOA, Longitudinal Gx force, and Normal Gy force (plane's reference coordinates). It starts at the stall warning and ends with the last FDR data recording, which lasts 60 secs. I found interesting the final Normal G load near and foun...

Zunzun.com has no advertisements, no fees and no requests for donations. The curve fitting source code is free for download. There is no 'they' at zunzun.com, just me. The name of the site is from my wife's Burmese nickname, ZunZun. James Oh god, free !?, the US is becoming socialist already.. ;) .

Re: Airbus crash into Mediterranean

From processing the flight data in the prel report and from pages 34 and 35 I get:

at 2000 ft (when the flaps are selected to pos 0):
IAS 165
Pitch -47
AOA: 0 deg

at 389 ft:
IAS 263
Pitch: -24
AOA: 11 degs (I wonder if it reached alph-prot)

Also there's at least 2 data errors in the report.

Re: Extract data from a graph in an image file

If you were capable of finding it yourself, why did you ask?
To keep Ed busy.

Didn't expect to find it myself. Might have taken a long time for others to reply. Also, now we have several progs and an excellent curve fitting web site. :clap:

Extract data from a graph in an image file

Someone posted much earlier about a software that extracts data from a graph in an image file. Does someone have a link to download the software.

Thanks
