We started our journey over 10 years ago. Since then SIG Aviation has been providing hands-on expertise to the aviation industry. We work pragmatically to ensure our advice matches your needs ... and more. We don't simply put words on paper, we help and assist to implement to satisfaction. You will find us unique, both in knowledge and expertise, as well as in our approach. 

"Some will tell you what you want to hear,

we will tell you what needs to be said."

Aviators will recognize a waypoint in our logo. That is exactly what we intend to provide. Direction and Guidance. Others might recognize a tree in our logo, symbolizing shelter and protection from harm.  Both reflections of our logo represent our goal and mission


Knowledge is what enables a person to visualize the different possibilities when addressing challenges. Different choices lead to different results although the direction might look similar. It takes experience to determine optimal decisions.  

We bring both qualities to the table.
