		Additionally, aircraft with constant speed propellers require an individual control for each engine that must be adjusted according to the aircraft’s phase of flight—a low angle for takeoff and a high angle for climbs and enroute flight.
		FADEC also simplifies the starting procedure by properly monitoring the priming procedure and ignition timing during initial engine start-up.
		Though FADEC is computer controlled, the engines have dual computers that far exceed the redundancy available with magnetos.

	FADEC - Encyclopedia, History, Geography and Biography
		FADECs have been produced for both piston engines and jet engines, their primary difference due to the different ways of controlling the engines.
		The FADEC may be powered by the aircraft electrical systems, and in most modern aircraft it uses power from a separate generator connected to the related engine.
		FADECs today are employed by almost all current generation jet engines and increasingly in newer piston engines, on fixed-wing aircraft and helicopters.

		Up to this point, if a customer was having problems with the engine or FADEC units, he had to either send them to the factory, or at times, a technical representative was dispatched to the customer in the field to diagnose and fix the problems.
		Various tests were done by factory personnel, instructing the FADEC to push all functions out of their normal parameters.
		Once the factory adjusted the FADEC units to their normal levels, the engine was able to start and run smoothly once more.

		If the engines were FADEC equiped (I think they were not) there would be no problem to firewall the throttles.
		FADEC looks at all parameters to determine if one gage is in error.
		FADEC will conclude the EPR is in error and increase the power until the power lever angle command is satisified or N-1, N-2, or EGT reaches a limit.

		FADEC is probably the most radical technological change in turbine engines since the Korean War.
		FADECs are now standard equipment on nearly all new turbine helicopter engines, such as those that power the Bell 407, 427, and 430; the MD 600N and MD Explorer; the Agusta A119 Koala; Sikorsky S-76C+; and the Eurocopter AS-350B-3 and EC-135.
		At the heart of FADEC is a computer that is connected to a variety of input sensors measuring TOT, torque, compressor and turbine rpm, rotor rpm, OAT, and battery voltage.

		The fadec computers, channels "A" and "B," are controlled by a pair of safety switches for preflight tests and emergency shutdowns.
		The fadec computer uses speed, temperature and pressure sensors to measure the health of each cylinder, as opposed to a mixture control, which throws more or less air/fuel at every cylinder all at once.
		The benefits of fadec are huge: better fuel economy (up to 15 percent better); longer engine life; high levels of reliability and redundancy, easy starting and smooth operation.

		As there seems to be little information on the 'net about the FADEC system and installations, I will try to provide more details than usual in case it is useful for someone else, if you have any questions drop me a line and I'll try and help.
		The main cabin FADEC harness needed to be modified to allow connection of the power and ground wires to the breakers and firewall ground respectively.
		After a trial fitting of the FADEC / SBC connection, I decided to remove the pins, shorten the connection further and solder it permenantly together.

		The FADEC 3 was developed and is produced by Hispano-Suiza and BAE Systems, and is marketed through their joint subsidiary FADEC International LLC.
		The FADEC 3 was developed on very tight deadlines, making it an unprecedented challenge for the teams at Hispano-Suiza and BAE Systems.
		Carrying on a collaboration that started in 1984, FADEC International was created by Hispano-Suiza and BAE Systems Controls (part of BAE Systems North America) to handle the marketing and support of FADEC units on commercial jet engines in the over 18,000-lb-thrust class.

		I had ordered the FADEC cabin harness kit a while back from Aerosance with annunciator box for two LED's rather than two incandescent lamps.
		I got another DPST Switch for FADEC B. I could use a SPDT, but the DPST switches are all the same type that I have in the main switch panel, so they all match.
		I ran the FADEC A from the main bus, and the FADEC B from the E-Bus.

	Rolls-Royce: Media Room
		The effort to certify this new Model 250-C47B FADEC results from an extensive and detailed engineering test program, during which Rolls-Royce was able to demonstrate that the probability of a ‘reversion to manual’ scenario is reduced by 60 percent.
		To assist with the introduction of the new FADEC system, Rolls-Royce has issued two Customer Support Letters (CSLs 6113 and 6117) which provide further details, and which request that affected operators register in order to allow all affected operators to be identified.
		This new FADEC system will also be certified on the Model 250-C47M turboshaft later in 2006, extending the same benefits to operators of the MD Helicopter Inc. MD 600N.

		We have finished all of our "new" specification data reading and the 72FM series propeller is safe to use with the FADEC system.
		The test results for the 72FM on the fadec system are very similar to those obtained during the initial testing of the 72FM on the standard O-360.
		The fadec system does not appear to have any limiting affects on the 72FM propeller.

		As a result, the FADEC system increases aircraft power, decreases fuel usage, and provides engine diagnostics information, which can be downloaded and monitored on demand.
		The FADEC system is controlled by redundant electronic components, which constantly monitor multiple sensors producing data, and react to changing conditions before a human would even be aware of them.
		The FADEC system has built-in redundancy for all components, which means the system always performs as expected, even in the case of battery failure.

		I ran the FADEC A from the main bus, and the FADEC B from the E-Bus.
		I was considering not having switches for the system power at all, and just wiring the FADEC busses direct to the main busses, but figured it might be a good idea to be able to isolate a system properly.

		FADEC systems could also be the missing link to enable current engines to use the unleaded fuels of tomorrow.
		All engines incorporating FADEC, from the factory or not, will change designators too; for example, IOF-240, IOF-360, IOF-550, etc. TCM estimates that the cost to retrofit an engine with FADEC will be in the range of $5,000 to $7,000.
		FADEC systems are born of both necessity and the need to bring aircraft engine technology out of the World War II era.

	V22 Osprey's 3.2 second accident Flight
		The aircraft was undergoing a post-maintenance functional check when a faulty FADEC caused the aircraft to experience an uncommanded engine overspeed.
		The flight control system automatically compensated for the overspeed, which is assumed to be more likely to occur in flight, by changing the pitch of the rotor blades to slow them down.
		The particular FADEC system is not unique to the V-22 or its Rolls-Royce engines, Taylor said.

	FLUG REVUE April 2005: FADEC is vital for engine control
		On every variant, the main task remains the same: the FADEC controls the output of the propulsion unit, taking due account of the operational limits, so as to achieve optimal performance data at every phase of the flight.
		Inside the housings, a total of up to six processors in two identical channels which could be switched over in the event of problems process the data and work out the relevant control signals.
		Naturally there is an additional requirement that the FADEC should not be too big or too heavy, weighing no more than 15kg to 27kg in civil applications.

		EEC is a Pratt term; GE use FADEC exclusively (at least on the commercial engine side) to designate their digital electronic engine controls.
		FADEC was not available on the CF6 series until the advent of the -80C2 variant.
		CF6 models equipped with FADEC are explicitly designated with an F suffix: CF6-80C2D1F, for example, is a FADEC-equipped engine with a rating plug for the MD-11.

		Delivery of the FADEC was promised by the main contractor, [Textron] Lycoming, within 23 months of the date of contract which was signed in January 1986.
		In the accident, the FADEC allowed the engines and the rotors (which cannot be disengaged from the engines) to accelerate out of control of the pilots—a so-called engine runaway.
		At the MoD's request, the FADEC was modified but there was not a rewrite of the software and flaws remained at the time of the crash on the Mull of Kintyre in June 1994 (see 1994).
