The old Aviation Safety Digests versus Flight Safety Australia Vive La Difference
Moderator
I have had a good response from the first set of enquiries and will PM any others who indicate interest. (Unable to PM or email megle 2 - if you would like to be involved, please do PM me with the copies you have on hand).
Suggest that no-one rushes into any scanning until we see who we have and what issues they have so that the workload can be spread in a controlled manner. Also we will need to get some standardisation on scanning parameters so that the image quality is more or less uniform.
I will chase up the copyright matter over the next week or two and then we can see where we might be able to go with the exercise.
regards,
John

Further to RENURUPP, I can also add 52,56,58-59, 69-83, 85-87,92-101, 104-107, 109-111, 115-126, 128-134, 138 and 147 plus visual flight and human factor.
A worthy contribution to the pursuit of AIRMANSHIP!

While copyright is one hurdle - has anyone done the sums to see how many megabyte 1 issue will consume when scanned at 300dpi.
I suspect each issue is going to be huge and each page would be a single jpg file.

There may be software available to help do the whole process i.e. integrating the scans, you type up the table of contents per issue and it saves it as a .pdf
Adobe .pdf files are the way to go as they are the standard for this sort of thing.
I did a similar exercise a couple of years ago to archive many mags to cut down space here i.e. turned each mag into a .pdf file but did not bother with a ToC because each January issue had a yearly index and they were for my own use anyway.
I scanned text-only pages @ 150dpi black & white, and images as (I think) 200dpi greyscale. Colour images I think I did 300dpi. Each mag (which was about the same size as the Digest except less pix) ended up about 2mb.
Anything you can do to cut down the file size helps i.e no point scanning a page greyscale if it is text-only. You will also get into making decisions whether something on a page eg. an ad with a pix warrants greyscale, or making the hard call that the priority is the text and go b&w.
It isn't an easy exercise by any means

Thanks Captain Midnight
That's what I thought - and if the copyright issue can be resolved, clear instructions need to be given to volunteer scanners.
Also - who is going to host this 'wealth' of data. You are talking about 150 magazines - of which I have about 75.
I haven't seen pprune agreeing!
BTW - the Commonwealth owns the copyright and I am sure will be prepared to SELL it. But not give it away.
Now that was a bit of a rush.

Still reckon one of the best articles in the old Safety Digest was the one about guy in the C310 going out of Tyabb to go to Canberra. He got caught with ice and then got below the LSALT going into Canberra at night time.

I won't be able to sort through my copies till my return.
Thats next Monday night.
They are stored in a safe place so I will probably find a few other treasures I haven't been able to find!

Whilst we're talking about the old ASD, I've been trying to get a copy of the report on VH-DBB which was the Mustang that crashed at Bendigo on the 15/2/71 (I think). I remember reading it in a dentists waiting room, probably around 1972, but haven't come across it since. Hoping that someone here might have it and PM me a scan of it. Thanks.
Funny how the same story can reappear with a slight difference. I remember that icing story into Canberra being a Navajo flown by a well known Canberra charter pilot. I think part of the story was in the BoM Aviation Met manual. I learnt a lot from the old ASD but the current magazine is in the same league as getting the Royal Auto or Open Road in your letter box.

Had a play with two sample copies, one of which needed a bit of post processing to remove marks, etc.
Initial observations are
(a) a good quality (for purpose) scan results in around 340kb/page. The set would take around three CDs or a DVD.
(b) an acceptable resample pushes this down to around 80kb/page. This quality is more than usable for a screen read and prints out to hard copy with more than acceptable quality. File sizes around 2-4 Mb would suit ftp downloads.
(c) process is reasonably labour intensive and, allowing for a fast machine A3 colour scan, some tidy up post processing, and pdf collation at both output qualities, is going to take around 1-2 manhours per issue, depending on the time taken for graphic tidy-up. Looking at the very much slower domestic A4 scanners one could double, or triple, this time estimate quite easily.
(d) A3 output appears to be the way to go to accommodate those double page graphic spreads which appear throughout the crash comics from time to time ...
I have asked a colleague to engage CASA re the copyright consideration and will advise what outcome may ensue.
Comments and thoughts ?

I'm looking for an article that appeared in the old ASD sometime about the early 1970s. The article was named:
"Inspector Day and the Demented Angel" or something like that. Can anyone help? If so PM me.
Thanks in advance.

As I recall there was a general release in the magazine that allowed you to copy and distribute it freely, in the interest of flight safety - provided you aknowledged the original source.

Auster Accident Vh-bpc 29 May 1959
I was wondering if you have any record of the accident to VH-BPC Auster J5B Autocar at Greenvale Queensland on 29 May 1959 in your collection of Australian Air Safety Digests. It was operated by Bush Pilot Airways and the pilot Len Holland and two swiss tourists perished.
I need it to complete an article for a vintage aeroplane club magagzine as a safety issue still exists with the aircraft type and not many current opertors are aware of the problem.

AUSTERJ5R
