After seeing theSN3308, I naturally assumed that its inventor and Sandel founder GerryBlock was a seasoned veteran of the avionics industry. So when I flew down to SandelAvionics in a northern suburb of San Diego to interview him for this article, I was quitesurprised to learn that the SN3308 was Block’s very first aviation product. […]

A couple of months ago, Ihad Avionics West replace some of the avionics in my 1979Cessna T310R. In particular, I changed out my decade-old Loran for a II Morrow GX50approach-certified GPS.

Both engines were running as well as they ever did, and AVwebeditor Mike Busch kept advising me to keep flying until the engines started showing […]

This is a five-part series on Active Noise Reduction in General Aviation. It came about because hundreds and hundreds of you have been asking good questions about ANR technology and its advantages in airplanes. This series is intended to provide G.A. pilots with a fairly technical and thorough understanding of this technology and the important […]

NOTE: Dr. Jim Yates provided substantial contributions to this section of ANR 101. Dr. Yates is Professor and chair, S.P.A. of John A. Burns School of Medicine, University of Hawaii, and principal of Audiology Associates Hawaii. Previous sections of this series have discussed active noise cancellation and the technical issues associated specifically with general aviation […]

In this section, we’ll be looking at the comfort and human-factors issues associated with ANR headsets. The ergonomics of the human head demand a wide range of adjustments to deliver comfort over hours of use. Optimizing the physical headset for pilot use Active pilots have been searching for ways to improve the physical aspects of […]
