Welcome to Wired!
EAA AirVenture Oshkosh is America’s annual cornucopia of aviation. Drawing all segments of the industry, it is the premier stage on which to debut new products and report the progress of innovations under development. Many things captured our attention, and the following made our Best of AirVenture list.
GE Aviation & Electric Aircraft
GE Aviation sponsored the inaugural Electric Aircraft Symposium, on July 30, and the Aviation Learning Center, home to related exhibits. When it comes to transport category aircraft, electric propulsion is not yet practical, but it’s perfect for aircraft systems because it replaces “big and hot with small and cool,” GE Aviation President Chet Fuller told the roughly 300 participants.
With its generators producing 1.4 megawatts, the Boeing 787 is aviation’s first electric airplane, right down to anti-icing, he said. It replaces pneumatic and hydraulic systems, which leak, and eliminates bleed air systems, explaining that heat and composites do not go well together. Looking to the future Fuller said smart grids would deliver electricity without waste, variable frequency power would eliminate AC and DC systems, and that fuel cells would eventually replace wasteful APUs.
Sikorsky Innovations Preparing Electric Firefly
The technology development arm of its parent company, Sikorsky Innovations debuted Project Firefly, an electric powered helicopter. A a high-efficiency U.S. Hybrid electric motor and digital controller drives the S-300c’s stock rotor and transmission. Side-mounted Gaia lithium ion energy pods provide the power. Approaching its first flight, the Firefly’s initial endurance goal is 15 minutes, said Sikorsky Innovations Director Chris Van Buiten. Upcoming flight tests will prove the system’s reduced complexity, noise, maintenance, and vibration. With no carbon footprint, it will deliver full power at altitude. This research will likely spawn new systems, he said, like an electric anti-torque tail rotor, which promises numerous power, noise, and vibration benefits.
Aspen Avionics Geo-referenced Charts
Aspen Avionics, working with Seattle Avionics Software, a software developer and data provider, has introduced geo-referencing on its Evolution EFD1000 and EFD500 multifunction displays (recently approved for Class III aircraft, which weigh 6,000-12,500 pounds). Besides displaying the aircraft’s relative position on AeroNav (formerly NACO) instrument approach charts and airport diagrams, this new capability comes at no cost, other than a database subscription. When users load the the July 28 Seattle Avionics chart update it automatically upgrades their systems with the new capability.
Avionics & Autopilots Act When Pilots Distracted
When multitasking in complex instrument airspace, single pilots can easily get distracted from their primary job of flying the airplane. Two avionics OEMs are addressing this problem from different angles.
Avidyne's DFC90 autopilot now offers speed-based Flight Envelope Protection. Currently, it’s STC’d for Cirrus SR20 and SR22 piston singles with Avidyne’s Entegra avionics system and S-Tec55X autopilot. With the autopilot engaged, it provides aural and visual warning when nearing high and low-speed parameters. If the pilot does not act, the DFC90 adjusts the pitch to maintain a safe speed while continuing to issue its warnings.
Garmin's Electronic Stability and Protection (ESP) System maintains safe and stable flight when the autopilot IS NOT engaged. Driven by G1000 and G3000 avionics, ESP monitors attitude and airspeed—and tells the autopilot servos to make corrective pitch and roll inputs when the aircraft approaches unsafe attitudes and airspeeds. Recoveries are programmed to not exceed airframe g-limits.
AeroLEDs Frugally Bright Landing & Nav Lights
New iPad EFB Applications
Jeppesen has introduced its Mobile TC application that searches and views terminal charts. Subscribers to JeppView get iPad access at no extra charge. Seattle Avionics Software is providing its ChartData to four new iPad apps: Flight Guide’s iEFB; Hilton Software’s WingX; Radenna’s SkyRadar; and Zivosity ‘s Beacon North America.
Until next time, stay 5x5, mission ready, and Wired!
