Sad News – Bruce Obit

I’m very sad to report that we’ve just learned of local aviation legend Bruce Van Dyke’s passing. An obit for him appeared in the paper, and I’ve found it online here (pasted in below). We will miss his bright spirit, while our hearts go out to local aviatrix Dorchen Forman. Blue skies, Bruce!

Bruce Wingfield Van Dyke

Obituary
b. March 18, 1922 — d. November 9, 2016

Bruce Van Dyke grew up in Fallbrook California and attended UCLA before joining the Army Air Corps to take part in World War II. He was a bomber pilot who trained cadet pilots and bombadiers, and stayed on after the war in the Air Force reserves, retiring as a major. During the war, he married his college sweetheart, Miki Harkness, and when the war ended he resumed his studies at UCLA. He changed his major, however, from physics to subtropical horticulture and his life revolved around plants from then on.

After graduating from UCLA with a degree subtropical horticulture in 1948, he moved with his young family to Carpenteria to take a job as instructor at Santa Barbara Junior College, and in 1950 moved into a house he built near Sheffield Reservoir. He left the Junior College after a few years and started his own horticultural services grafting, pruning, and spraying, and consulting homeowners and ranchers on plants. In the years that followed he was involved in almost every aspect of gardening and horticulture in the community. He was a horticulturist on staff at Lotusland for over twenty years, and worked on many other fabulous estate gardens in the community. He worked in all sorts and sizes of gardens and there are trees in backyards all over Santa Barbara that he grafted, gardeners throughout the county who learned how to prune their fruit trees from him, and countless friends who remember him for his good humor, kindness, and love of plants.

He was generous with his time and knowledge. From 1953 to 1996, he taught popular adult education classes in home gardening. He wrote a garden column for the Santa Barbara News Press for 33 years, and managed the Santa Barbara Orchid Show for 21 years and Santa Barbara Flower and Garden Show for 5 years. He was a board member and president of Santa Barbara Beautiful, served as a City Parks Commissioner for Santa Barbara for 18 years, a member of the City Street Tree Advisory Committee for 25 years, and was a trustee of the Santa Barbara Botanical Gardens. When the city of Santa Barbara stopped pruning the rose garden on Mission lawn, he drafted his good friend Duke McPherson, and the two of them started a volunteer pruning effort that has turned into a Santa Barbara institution in which hundreds of people take part. For all this he received many awards and acknowledgements including the Heritage Oak Award from Santa Barbara Beautiful for lifetime achievement.

He was also an avid hiker and made many summer trips to the Sierra Nevada. He swam regularly at the YMCA and made many friends there. He and Miki traveled extensively in Latin America, South East Asia, and Africa. He loved snorkeling on coral reefs, photography, and of course his own home gardens. Miki Van Dyke died in 1996 and in 2003, Bruce married Dorchen Forman, and lived the remainder of his life with Dorchen in her beautiful Goleta home surrounded by fruit trees and flowers. Dorchen rekindled Bruce’s interest in aviation and the two of them crossed the country many times in her Cessna 172.

Bruce is survived by his wife Dorchen, daughter Christopher, son Peter, grandchildren Papaya and Nicholas, six great-grandchildren, and many dear friends. The family wishes to acknowledge with gratitude the loving care provided to him at the end of his life by Elza Hernandez and her caregiver team, and in his last days by Santa Barbara Visiting Nurse and Hospice Care.

A memorial will be planned for a later date. In lieu of flowers, the family suggests donations to Santa Barbara Botanical Garden or Santa Barbara Visiting Nurse and Hospice Care.

More ADS-B (coverage)

I was inspired by Carl’s excellent Thursday presentation to look up a few online ADS-B resources regarding the FAA Ground Station transmitters. Here’s where the FAA says (interactive link at the bottom of this page) you’ll get ADS-B in reception (non-coverage shown in salmon color) at 500’AGL in the SouthWest region:

ADS-B Coverage at 500' SW

ADS-B Coverage at 500′ SW

In the hope they may be of interest or value to other members, below are some links.

ADSB Handout & Slides

Here are the handout and slides from Carl’s great 1/14/2015 presentation on ADS-B, and Still’s demo on how to build a “Stratux” ADS-B In receiver. To download the complete 31MB 10 page PDF of the handout & slides, click this thumbnail image link: ADS-thumb
For just the printed handout (first page of the slides, 0.05MB) click this thumbnail image link: Click for 31MB PDF

Following are selected pages in web format with links and some notes I took from the presentation. Slides from the presentation containing links to original online sources [Stratux hardware, etc] in the first page below are omitted – click the links here or in the complete PDF to see those clearer and fully functional originals online. Only the slides from ADS-B introduction by Carl are included below. I didn’t take notes on the Stratux building demo, but maybe someone else will post some if you request it. I’ve inserted a few comments from my notes, in green italic font, for the benefit of anyone who wasn’t at the meeting. –JW


Handout (page 1 of Slides)

ADS-R (Rebroadcast) (AKA ADS-B Traffic) Every second “Hockey puck” 15nm radius; +/- 5000 feet

Antenna diversity
Own ship shadow
ADS-B OUT Class A, B, C. Class E above 10,000 (but not below 2500 AGL)

Information on how to build your own ADS-B IN receiver:
https://www.reddit.com/r/flying/comments/3g7urb/the_11390_adsb_receiver_for_foreflight_or_pretty/

Parts to Order:
http://amzn.com/B00MV6TAJI $69.99
http://amzn.com/B00P2UOU72 $25.95
http://amzn.com/B00JM59JPG $13.99
http://amzn.com/B000TGSPV6 $3.97

JW Notes: Total parts $113.90 plus iPad and ForeFlight with subscriptions, for a single-band (dual band in development) “Stratux” similar to the Stratus demonstrated by Carl. John Rodkey uses a Stratux with the less capable but free Avare app on an inexpensive Android Nexus 7, thus saving on the iPad and subscription expenses. I also briefly mentioned the simpler $13 solution I’ve found for my own Nexus 7 using the same type of “SDR” receiver as Stratux but eliminating the $70 “rPi” computer and $14 battery by using the $2.50 Android ADSB Pro app to display 1090-ES & 978-UAT with free Avare (this works somewhat better than a Stratux for Avare, but has 2-6 hours of battery life unless ADS-B power is swapped to my Nexus 7 in flight).

Software that runs the Stratux:
https://github.com/cyoung/stratux/releases
Pick the first Green, “Latest Release” Image writer software

Windows https://www.raspberrypi.org/documentation/installation/installing-images/windows.md

Mac OS X http://ivanx.com/raspberrypi/

Some ADS-B links


(page 2 of slides)

ADS page2

JW Notes: The top image shows dots approximating the locations of ADS-B transmitters and an impression of their coverage areas in the blue circles as of 2014. Carl pointed out the differences between UAT weather update interval & transmission interval (e.g. transmissions are not always the most recently updated weather image). Also note that CONUS (national) images are transmitted less often than regional, so BOS weather can take longer to get flying near SBA than SoCA weather will.


(page 3 of slides)

ADS page 3

JW Notes: By using a Stratus or home-built “Stratux” receiver with ForeFlight you can get free UAT weather aloft that is equal in most respects to subscription satellite service. Carl pointed out that both services provide delayed radar images (due to the required processing time) so they should never be used for finding a route through weather.


(page 4 of slides)

ADS page 4

JW Notes: At the top-left of the ForeFlight map screen is info about how many ADS-B transmitting towers are being received, and currency of the info.


(page 5 of slides is a blank transition to this page 6)

ADS page 6

JW Notes: The top image demonstrates how ADS-B traffic is incomplete, especially when no aircraft are equipped with ADS-B Out. At the bottom-right corner of each image is an inset showing how ForeFlight would depict the situation in your non-ADS-B Out aircraft. The bottom image shows how an ADS-B Out aircraft is provided a “hockey puck” shaped area near that aircraft that only shows those aircraft, and not the one close behind you.


(page 7 of slides)

ADS page 7

JW Notes: When you’re flying an ADS-B Out equipped aircraft, all the aircraft nearby (inside your “hockey puck” area) are transmitted to you and anyone nearby with only ADS-B In (Stratux, etc).
