Ontic (Hall 5 B219) has signed a license agreement with Tempe, Arizona-based Curtiss-Wright Controls to further expand its electronic and electro-mechanical portfolio–including landing gear levers, tiller modules, pilot LED checklists, flight control surface indicators, rudder trim switches and push-to-talk switches. These products will be moved to Ontic’s manufacturing facilities in Chatsworth, California and Cheltenham, UK.
Flight control surfaces
The FAA has issued a notice of proposed rulemaking for an Airworthiness Directive for certain Embraer Phenom 300s. It is based on an unsafe condition as a result of an inadequate number of drain holes in the primary control surfaces (rudder, elevators and ailerons), which may allow water to accumulate in the control surfaces.
Whenever a manufacturer develops a new airplane, engineers have the opportunity to incorporate new technology into the design. With the large-cabin Columbus, Cessna engineers didn’t opt for a composite airframe or an all-electric systems architecture, but they have chosen an innovative approach to fly-by-wire flight controls.
The Sino Swearingen SJ30-2 that crashed in a remote area of Texas on the morning of April 26 was on the second in a series of flights to complete flutter certification before it suddenly rolled and went into an uncontrolled descent into the ground. Company test pilot Carroll Beeler, 59, was killed in the accident. No one else was aboard.
A new control surface could reduce induced drag on commercial and business aircraft by up to 14 percent, resulting in fuel savings of more than $400 million per year across the entire U.S. air transport fleet. So claims Utah State University aeronautical engineering professor Warren Phillips, who recently introduced the devices, which he calls “twisterons.”
