Whereas most technical manuals tend to be thick, tough-to-follow tomes, Qref's unit-specific Bendix/King KLN 90B how-to guide eliminates unnecessary verbiage and instead presents step-by-step instructions on mastering virtually all of the KLN 90B's extensive features. Further enhancing the guide's easy-to-follow explanations are several vibrant photos of what you can expect to see on the unit's display. Going even further, the guide features convenient side tabs and a detailed Table of Contents that make it quick & easy to track down exactly what you're after. A remarkably useful, low-cost resource that should be a "no-go" item for every Bendix/King KLN 90B user.
What a relief
The KLN-90B was so overwhelming to me, but once I got the qref quick reference guide, I was loading flight plans like I had been doing it forever.
