objective hazards

In the mountaineering world, climbers talk of objective hazards: those dangers that strike regardless of careful planning, skillful preparation or thorough training. The Cirrus Airplane Parachute System addressed the objective hazard of a wing falling off as a result of a midair collision that Cirrus Aircraft co-founder Alan Klapmeier survived as a young pilot. The experience convinced him that solving this for pilots—and their passengers—should stand at the heart of the Cirrus philosophy. A widescreen horizon line on a primary flight display—introduced into multiple single-engine piston airplanes around the same time as CAPS—was intended to reduce the hazard of vertigo, induced by the often-objective risk of flying into suddenly reduced visibility. In VFR scenarios, this is especially applicable to night flying or over featureless terrain such as a lake—as Flying contributor Ben…


VALUING SERVICE I typically enjoy Mr. Younger’s column, however, I have to take issue with his comment about not being able to cheer as easily for the F-35 as for the P-51 [from “Stoke,” November]. Please leave the personal politics out of Flying magazine. Whether or not you’re fond of the current administration, the fact remains that the F-35 is a remarkable piece of American ingenuity and manufacturing flown by outstanding young Americans who risk their lives on our behalf every time they strap into it. I’ve had the privilege of training some of those aviators myself as an active duty Marine Corps and Navy Reserve instructor pilot, and I can assure you that they are worth cheering for. Dave Elert via email Hi, Dave, Thought I’d take a moment to respond to your…

ipreflight genesis

Aircraft Performance Group launched its iPreFlight Genesis app for the iPad this past year, delivering a robust flight-planning and performance tool that we’ve had the chance to follow through additional layers of development. APG has optimized the app for the business-aviation market segment, which the company feels it knows best. The app is designed for use across the market, both on the flight deck and in a wide range of operations. The app is tail-specific, so we had a Cessna Citation M2 loaded in for our testing. Without referring to prior notes, we downloaded the app onto a fifth-generation iPad Mini. After importing the latest updates, we were underway. Weather, airport data, terrain data and other updates come in various frequencies—daily, if needed. In this way, the app works with the…

vu systems’ vu cube

Instrument flying recently changed forever when Vu Systems launched the world’s first passive millimeter wave sensor for aviation called the Vu Cube. At first glance, the 29-pound sensor resembles a retro black-and-white TV from the 1950s, but that sensor’s ability to see through heavy clouds, thick fog and even snow make it far more valuable. When the Cube’s output is projected on a heads-up display, pilots can see as far as 2 miles ahead of the airplane, making reliable takeoffs and landings in poor weather possible—right down to the flare, touchdown and rollout. Representatives from Vu Systems say PMMW tech is complementary to the infrared-radiation cameras of today, providing the necessary punch to see through the weather where IR is ineffective. Until now, landing in poor weather required a significant onboard…

avidyne atlas

Avidyne debuted its Atlas Flight Management System for Part 25-certificated aircraft in October 2019, bringing its integrated flight deck technology into jets utilizing a console layout in the cockpit. Certification is expected in 2020. The multifunction FMS combines a range of features in the single-box, Dzus-mounted design. Flying spoke with Avidyne president and CEO Dan Schwinn to understand more about the philosophy behind the step up from this past year’s debut of the IFD into Cessna Citation 525 models. “We’re a new entrant in the turbine FMS market, but the technology is very mature, very stable,” Schwinn said. The design aims to achieve Avidyne’s objectives of providing a lower-cost system with a lower-cost installation as compared to other FMSs in its class. Schwinn foresees lower operational costs, in part because the chart/data…

atlanta dekalb-peachtree (pdk) rnav (gps) y runway 21l

With Atlanta’s Hartsfield-Jackson International Airport (ATL) notorious as the busiest airport in the US—with passengers carried at just over 103 million—the air traffic in the Atlanta area can, at times, be intense. DeKalb-Peachtree (PDK), just 17 nautical miles northeast, is a perfect GA airport for anyone visiting the metro area interested in avoiding ATL traffic. When PDK winds blow from the west and south, the RNAV (GPS) Y Runway 21L is regularly used during IFR conditions—and often just to establish a stable arrival during VFR conditions. A. AWSON ARRIVAL Pilots en route to Atlanta from the northeast should note the (GPS) Y procedure “is not authorized for arrivals at AWSON [while] on V5-311-417 westbound.” From a planning perspective, an arriving pilot might want to consider including AWSON in their flight plan. Arrivals…
