About Us - EAI

Experimental Aircraft Info (EAI) started when friends were asking me questions like: "I'm planning a flight to airport such and such on this or that date. Do you know where to find the latest weather en route and information for that airport ......?". I'm sure you will recognize this. Thus the idea for this website was born.

We aim to provide concise information on several interesting subjects for pilots and other aviation enthousiasts, thus refreshing once learned knowledge and not pretending to be a full fledged pilots course. The level is comparable to that of a commercial pilot license (CPL), where needed we will delve deeper explaining subjects further. Articles will be to the point and whetting your appetite for more, leaving you to study the topic further at your own pace.

Finally, if you have enjoyed and found this site useful, consider a donation or become one of our patrons at Patreon, click here to help us. This will keep our site and its information free of any membership. Thanks!

Ten Year Anniversary

Yes, we have been on the World Wide Web for over a decade now!
It has been a lot of work, a number of site rebuilds, infrastructure changes and a lot of time but we have enjoyed it to the fullest! We would like to say thanks to all our visitors who have made us grow and become the site we are now. Thank you very much for that!

Technical Stuff

This website is developed under Ubuntu Linux with BlueFish and Windows with PSPAD in HTML5 / XHTML1, CSS3, PHP7 and JavaScript / AJAX / jQuery. We implement new useful features as they become available in mainstream browsers and mobile devices with their fluid layout.

Our Content

Is based on known facts, personal experience, studies and valid peer reviewed, robust science. We do not present subjects that are known to be not verifiable. On some of our pages we show physics, notably weather subjects, and those are based on confirmable facts and not on beliefs, false consensus, faith or political views. We would like to keep an open and somewhat sceptical view with an inquiring mind.


HTTPS/SSL is implemented as a security measure to ensure the webpage is delivered fully encrypted to the end user. HTTP/2 low latency is also active but that depends on which browser is used to access the site.

Content Delivery Network

Protected by CloudFlare

Our content is delivered via the CloudFlare Content Delivery Network (CDN) and this increases our website speed as users will connect to a data center close by where our site is then cached. CloudFlare also protects against malicious activity from site scrapers (rate limiting), spammers, botnets, DDOS attacks and other vulnerabilities.

Browser Compatibility

Testing has been done on several mobile web and desktop browsers such as Chrome, Mozilla 1.7 / Firefox, Opera and Safari, Netscape Navigator 9.x (the final version), Konqueror 3.5, Flock 2.5.6, Maxthon 3.x, MS Edge and Internet Explorer versions 9, 10 and 11 (as IE8 and lower are not really W3C compliant, so please do update!) browsers operating under Windows 200(0/3/8/12/16) / XP / Vista / Windows 7, 8 and 10 and several 32 and 64 bit Linux desktop operating systems.

To maintain a good user experience we recommend a minimum resolution of 1152x864 pixels and the pages will expand no wider than 1190 pixels to maintain the Fibonacci sequence (Golden ratio 1,618) with the side menu for layout purposes.

Mobile Devices

Due to the layout of the site we support tablet devices with screen sizes from 7.0" and up (resolution 1024X600 with one zoom out level). On mobile devices with smaller displays the site will work responsively but readability will be somewhat impaired, which is typical on those devices.

RSS feed

We also have a live RSS (v2.0) feed available to be used by RSS capable readers. This will make it easier to follow the updates here on the site as they are available in your favorite RSS reader almost instantly. Subscribe to our updates or see the RSS icon in the menu above.


VigLink badge

We run ads on the site to pay for the hosting, other CDN expenses and also to keep development/ updating of the site ongoing. Nothing is free on the Internet. You might want to think about that, should you be using an ad blocker.

You may also choose to support us via Patreon, that is very much appreciated! Click here to do that now!
