GPS: Trust, But Verify
Almost daily rains dampened flight activity last week, with the concomitant growth in the acres of grass needing mowing around the Butler airport. If you think you’re having trouble keeping your home’s lawn in check, consider the margins around a ¾ mile long runway and taxiway, hangars and frontage. It’s been a hard year for the crew and equipment needed to keep up with mowing at the aerodrome.
Other than for the few Kansas City-based trainers coming in, and a departing Colorado-bound Cessna 182, transient traffic was light last week, no doubt due to the weather. Locally, there were multiple AirTractor agplanes working full time from the BCS base, Gerold Koehn had his Cessna Skyhawk out, and Gerald Bauer and Jeremie Platt took their planes to Harrisonville to represent us at the third-Saturday pancake breakfast.
Last month’s flight-into-terrain accident at Sierra Blanca, New Mexico, when a King Air medevac airplane impacted a mountain while descending to pick up a patient, seems to have been complicated by military GPS jamming. Jamming takes place regularly in the Southwest for training exercises. We are all so spoiled by our GPS navigation receivers that we can hardly find our way without them. It’s important to realize that the Global Positioning System belongs to the military, and we use it at their behest. At midnight in the mountains, the King Air crew didn’t realize they had lost signal; you must always crosscheck one navigation method with another.
The “free” presidential Boeing 747-8i bequeathed to the U.S. by the Emir of Qatar has been delivered to Andrews AFB outside Washington, DC, where it is being given final preparation for entering service, probably as Air Force One. Lavished outfitted in royal service, it underwent special outfitting for the VIP fleet. It’s to relieve the hard-working 36-year-old Boeing 747-200s, until Boeing delivers the two new VC-25s on order, now expected in 2028.
Much has been made over the go-around by a Delta Airlines pilot at Boston week before last; although cleared to land, he was aware of an American Airlines plane that was cleared to take off on an intersecting runway, and when he saw it moving after a delay he realized it would be too close and pushed up the power to climb away. It seems to me that the system worked just as it should; human at the controls evaluated and took action. Case closed.
Our previous column had a question about a monument near Bazaar, Kansas in the Flint Hills. Tim Enos knew the answer; it marks where a TWA Fokker trimotor airliner lost a wing in 1931, carrying famous football coach Knute Rockne on his way to Los Angeles. Next week’s brain-teaser is, “what is the approximate weight of a cumulus cloud measuring one kilometer on each side?” You can send your answers to kochhaus1@gmail.com.
