INTRODUCTION
Although not state of the art when we release the Aerosoft PBY Catalina X, the KLN-90B is one of the
most used navigation systems in aircraft . The main reason is that it is a very easy replacement as it
fits in the avionics bay, all the connections are available and you can pick up a copy for a very
reasonable price. And for that price you get a whopping load of information, not only a solid
database of navaids, waypoints and airports but also the answer to just about any calculation you
might need.
The problem is that the KLN-90B is small. It has just a few knobs and a small screen. So everything
has many functions or is shown in abbreviated text. Yet the interface is logical and when you know
one function you understand the next a lot faster. It’s a steep learning curve that ends on a smooth
platform where just about everything you need is displayed and connected to your aircraft. You
need to invest a few hours to really learn to use it. But the people at Bendix/King are the kings (pun
intended) of avionics and the KLN-90B sold many tens of thousands of copies and is still in high
demand.
Because the instrument is complex and not easy to operate we decided to only
use a 2d representation that can be used. The 3d version in the VC will always
show the correct display however.
Aerosoft licensed these gauges from Don Kuhn. He has become a friend by now.
