49% Off to Celebrate Super Bowl 49 (XLIX)

If you’re even remotely interested in football, this is the Sunday of all Sundays — Super Bowl Sunday.  And if you live in Seattle, it’s pretty hard to miss that the Seattle Seahawks are in the Super Bowl for the second year in a row.  Being a loyal part of the Seattle community, Seattle Avionics decided to do our part in offering a pretty spectacular sale to coincide with the game.

As this is Super Bowl XLIX (# 49), we decided to put all our best-selling products on sale for 49% off.  So the IFR + VFR annual subscription to FlyQ EFB is just $61 instead of $119, an Aspen certified subscription is $152 rather than $299, etc.  It’s a pretty amazing deal and ends Sunday night.


Enjoy the game and — Go Hawks!


The Return of the Newsletter!

Seattle Avionics has been making software for pilots since what seems like the dawn of time (2003).  We published an email newsletter for years and folks really seemed to love it, especially the Tips and Tricks section.  Over time, other things got in the way and we stopped publishing it.

During the past year, our business has so dramatically expanded that we think it’s time to bring Flight Log, our newsletter, back.  You should have it in your inbox now (or click here to read it).  We cover what’s new with our apps and ChartData offerings, look forward to what’s coming, and include lots of great tips and tricks (especially for our #1 rated app, FlyQ EFB).  Please let me know what you think!

Outage Resolved

Over night, we had an outage for a few hours due to an error made by an engineer at our Internet Service Provider.  They corrected it at about 3:35 AM Pacific time and all is working normally again.  We deeply regret the problem and have taken steps to ensure it will not happen again.  For those of you interested in the details, the following explains precisely what happened:

Our system is made of multiple, highly redundant, and constantly monitored systems to help ensure a general outage cannot occur because there is no single point of failure.  We use the same provider and same system that Netflix uses to distribute movies all around the world.  None of our servers or data distribution nodes had a problem.

However, there is still one single point of failure — human error.

Every Web site and Web service on the Internet uses something called a DNS (Domain Name Service) to map the URLs you type (like http://www.seattleavionics.com) to the internal numbering system of the Internet  — what’s called an IP or Internet Protocol number.  This is a paid-for service and Internet Service Providers routinely do this for their clients.  It has to be renewed every year or two for a small fee and the fee is generally paid automatically to ensure no outage.  This was precisely the case here — our domain name (SeattleAvionics.com) was automatically charged to our account before the name expired, as usual.

However, the system used by our ISP to feed the renewal into the global Internet DNS, apparently failed for some reason and the ISP did not notice it.  Because computers maintain a memory (what’s called a cache) of known IP addresses for recently visited Web sites, the renewal failure was not immediately apparent because computers were still using the IP address they had in memory.  At some point late last night, those caches began to expire and when computers asked other computers who SeattleAvionics.com was, the other computers began to answer that they did not know and, for all intents and purposes, all our systems became invisible although they were still running fine.

We have automated alerts and human monitoring that frequently checks for any problems and they detected this problem.  We immediately contacted our ISP (it was very, very early in the morning where they’re located) and their emergency technicians determined the cause of the problem and corrected it manually.  Due to the nature of the Internet, it then took a little time for all the computers, iPads, and iPhone that use our system to get the new connection information. At about 3:35 Pacific time, most devices would have been able to see and connect to SeattleAvionics.com again.

Happy New Year!


On behalf of everyone here at Seattle Avionics, I wanted to wish all our customers and friends a very happy New Year.

I hope you had a great 2014.  For us, 2014 was an incredible year with our highest retail sales ever, major new versions of FlyQ EFB and FlyQ Pocket, more companies signing up to use our ChartData aviation data, a brand-new Web site, a new blog (this one!), and a major update to our Data Manager app,

For 2015, we’re extremely excited to be taking full control of both FlyQ EFB and FlyQ Pocket and have very significant updates to both in the works.  In fact, the FlyQ EFB release planned for January includes a HUGE surprise feature we’ve been working on for some time.

Also in late January, we expect to release our incredible new ATLAS flight planning and information tool to folks who agree to test it.  See:

Thanks for flying with us!  2014 was record-setting and we could not have done it without you.  Now hold tight for an even more spectacular 2015!
