Avialogs is now free.


Why? There were no large update on the site for around one year and developping the new site in parallel demonstrated I was hitting a dead end. The first option was to keep the subscription system but It would have required on my side extra hands for the development and more time in the site. Taking this way would have meant more expenses and a pressure to develop the site to make it profitable. 
With a small daughter at home and a full time work, I did not see the possibility to make this happen. I had three other options: the status quo, which was not possible as the site has to be updated soon (required by the end of life of some software components), closing the site, an option I eliminated: Avialogs exists now for 14 years, it is used across the world and I don't want this to happen. The last option was to make Avialogs free. This is what is happening. 

Avialogs is no more an organization or a commercial venture, this is my personal website dedicated to aviation and I intend to share with you photos, books, manuals and other documents I collected over the year and available under public domain or crown copyright. This is also the platform I will use to communicate about my aviation projects and upcoming books. 

I hope you will like these changes,

 This week's addition to the site counts 24 new documents, several on the Folland Gnat, a British jet trainer designed during the '50s by Folland Aircraft. The Red Arrows used the Gnat from 1965 to 1979.

Also available are one Banshee flight manual and many instruments-related documents.

As you probably know, I manage the site alone during my free time. In twelve years, the site grew from a simple blog to a website hosting more than ten terabytes of data. I will not surprise you if I say costs are increasing and help is required to develop and maintain it. I do not plan to raise subscription prices, but free access to manuals will end from September first. The subscription model will not change, and unlimited access to all documents for subscribers; This is the principle on which I started this project in 2010.
 As additional income is required to hire a developer part-time, Avialogs business model needs to evolve to ensure its sustainability. I understand this news will not please many, but the number of alternative options is minimal.

Don't hesitate to contact me if you have any questions or suggestions (by replying to this email). 

The yearly subscription cost is less than 10 cents (USD) per day.  A twenty percent discount is offered this month. At checkout, use the coupon AVIA20 valid on yearly subscriptions. The subscription cost for the next twelve months are (there will be no price increase):

- Two years access: $USD55, renewal USD$32
- One year access: $USD32, renewal USD$28
- One month access: $USD3.85, recurring.

 This week's addition to the site counts 12 new documents: Several Sea Fury Manuals, including a Schedule of Spare parts with beautiful plates describing all Sea Fury components, a North Star Pilot Operating Instructions, a Vickers Viscount manual, several British navigation instruments manuals (Compasses, Drift and astronomical). I will add more instruments and support equipment manuals within the following weeks.

The next version of Avialogs is coming soon, and here is some news about the new design. Avialogs will support IIIF standard (3.0) and manifest. This standard is used by many libraries and universities worldwide and will allow easier sharing of all resources. It requires processing all documents and pages already online (more than 1.5 million), and a server is dedicated to this task, but it will take a few weeks to achieve. The new viewer used by Avialogs will be Mirador. You can already see a demo here: https://www.avialogs.com/demo/viewer/index.html  (Image rotation and text search will be available in the final version.)

Your feedback about the usability/performance is more than welcome (reply to this email to send me your comments).
