To meet increasing demand for electrical power to keep portable electronic devices (PEDs) operating during flight and charged for arrival, a new in-seat power system (ISPS) is on display at NBAA 2013. The new dual-mode EmPower system was developed by Astronics Advanced Electronic Systems, a wholly owned subsidiary of Astronics Corp. (Booth No. N5129).
The FAA proposes an airworthiness directive for the Cessna 750 Citation X prompted by reports of direct current (DC) generator overvoltage events. The generator control unit (GCU) overvoltage protection circuit can become damaged and allow high voltage to pass through to the airplane systems and electrical components, which, if not corrected, could result in smoke in the cockpit and loss of avionics and electrical systems.
Avionic Instruments is at Booth No. 3417 with two of its newer electrical power generation, conversion and conditioning products. Its 2-KVA static inverter is designed and qualified with current component technology and innovative thermal/mechanical techniques. The design provides overall device isolation, excellent overload and non-linear load handling capability.
The Nor’Easter that tore through the Northeast over the weekend caused flooding damage and power outages throughout the region and spurred New Jersey to declare a state of emergency. At Teterboro (N.J.) Airport, wind gusts of nearly 60 miles per hour were reported, knocking out power to the control tower and remote antenna transmitters around 6 p.m. Saturday, resulting in an immediate switch to back-up batteries.
Unitron (Booth No. 3853) is adding a new programmable power supply to its PS Series product line. The new unit operates from a wide input frequency (30-600 Hz) and provides 50-, 60- or 400-Hz output power in 115V, 115/200V or 230V output configurations. The PS Programmable Power Supply is available in single unit power ratings up to 3.5 kVA, or with the paralleling option, up to 40 kVA.
Mid-continent Instruments (www.mcico.com), based in Wichita, has been marketing its 4300 series electric attitude indicator since the middle of last year. What makes the instrument notable is its lead-acid cell array battery backup, which provides up to 60 minutes of operating time in the event of an electrical failure in the aircraft.
In a November 7 response to a request by Sen. Barbara Boxer (D-Calif.), the DOT Inspector General’s office reviewed a recent series of ATC equipment outages in Southern California, as well as a problem with a runway-incursion alerting system at Los Angeles International Airport (LAX).
Controversy continues to swirl around the FAA’s September 2005 aircraft thermal and acoustic insulation regulations, which went into effect in January. The agency amended the original regulations after discovering that the wording implicated a much broader range of components than intended.
The Eldec division of Crane Aerospace & Electronics (Hall 4 Stand G20) is showing an example of what it reckons is the ideal means of reconciling a growing demand for more powerful on-board electrical equipment with new restrictions on the effect individual loads can have on the aircraft power supply.
