Die werden sich gegen die Konkurrenz aufstellen und nicht ihr eigenes Progamm kannibalisieren.
Es ist übrigens wirklich erstaunlich und sehr interessant mitzuverfolgen was sich bei den BizzJets so tut
Viele Innovation, viele neue Modelle,...ich freue mich jeden Monat auf die neue Flug Revue, die schreiben recht umfangreich über BizzJets

Unter einer FADEC wird in der Luftfahrt im allgemeinen ein voll digitaler Triebwerksregler verstanden. Die Abkürzung kommt aus dem Englischen und steht für Full Authority Digital Engine Control. Damit ist gemeint, dass dieser Regler die gesamte Kontrolle über das Triebwerk hat, und darüber andere Komponenten, wie die Leitschaufelverstellung, Kraftstoffbemessung oder Gehäusekühlung kontrolliert. Die Kommunikation zwischen Flugzeug und Triebwerk erfolgt in der zivilen Luftfahrt über ein standardisiertes serielles Protokoll, ARINC 429. Dieses ARINC 429 Protokoll wird auch zur Kommunikation anderer Komponenten im Flugzeug benutzt, ist also nicht auf das Triebwerk beschränkt.

Hauptstellgröße für den Triebwerkschub kann das EPR (Engine Pressure Ratio), das Druckverhältnis der angesaugten zur ausgestoßenen Luft oder auch die auf Umgebungsbedingungen korrigierte Fandrehzahl sein. Es gibt aber viele verschiedene Regelkreise, die sich an den notwendingen Anwendungsfall des Triebwerks anpassen. So wird während des Anlassvorgangs ein anderer Regelkreis benötigt, als wenn das Triebwerk stabil auf Leerlaufdrehzahl läuft und dann als Regelparameter z.B. den Hochdruckverdichteraustrittsdruck oder die physikalische Hochdruckverdichterdrehzahl überwacht.

Die Entwicklung dieser Regler und die anfänglichen Vorbehalte gegen diese Technik führten dazu, dass der Regler komplett redundant aufgebaut ist. Sämtliche Kabelverbindungen zu den Stellgliedern am Triebwerk werden 2-kanalig angesteuert und abgefragt. Erst die Entwicklung dieser digitalen Regler ermöglichte es, die von den Fluggesellschaften geforderten Kerosineinsparungen zu realisieren.

Ein weiterer positiver Nebeneffekt ist die extrem verbesserte Kontrolle über den Lebenszustand eines Triebwerks. Die Daten werden zentral erfasst und gespeichert bzw. werden bereits während des Flugbetriebs an die Wartungsbasis übermittelt (Telemetrie) und notwendige Reparaturen auf ein zeitliches Minimum reduziert.

Die Entwicklung dieser Technik war ein Beitrag zum 2-Mann-Cockpit, der früher notwendige Flugingenieur zur Überwachung und Kontrolle verschiedener Subsysteme eines Flugzeugs wurde durch Rechnertechnik ersetzt.

Führende Hersteller solcher Regler sind in der zivilen Luftfahrt die Firmen Hamilton Sundstrand für Pratt & Whitney und IAE. Für die Triebwerke von General Electric oder CFMI kommen Regler von BAE Systems zum Einsatz. Im militärischen Bereich ist in Deutschland z.B. die MTU verantwortlich für die Entwicklung und Produktion des Triebwerkreglers des Eurofighter.

Cessna VP Roger Whyte says the company has "taken orders" in addition to the 36 it reported for the $27 million Columbus 850 large-cabin business at the end of the first quarter of this year and it's hit the road in Europe with an elaborate display on the aircraft. At a news conference at EBACE 2008 in Geneva on Monday, Whyte also announced that Vought will build the wings on the 70-foot-long aircraft, adding to a long list of outsourced assemblies that Cessna has traditionally (although not exclusively) built itself. Spirit Aerosystems is building the fuselage and tail section. Meanwhile, the company continues to ride the wave of interest in private aviation and is reporting a record $14.5 billion order backlog.

There are now 930 Cessna jets flying in Europe and more than half the company's business is now outside the U.S. The big market in Europe is Germany with more than 200 Cessna jets in the air. Russia, the MidEast, Brazil and Canada are also growing market

In mid-June, Cessna expects to lay off another 700 workers, as a result of the suspension of the Citation Columbus project, which was also announced today.

The company says the suspension of that program is due to low demand in the business jet economy.

The Columbus is Cessna's largest jet yet. The company is building a plant at its Mid-Continent Airport facility for final assembly, as well as receiving help from Spirit Aerosystems to build the aircraft's fuselage. Spirit is also building a new plant for Columbus production.

Cessna's previously announced two week shutdown in June has also been extended. That furlough will now run four weeks, from June 22 to July 19.

In another cost cutting measure, the company is also shutting down their Bend, Oregon facility and moving that work to Independence, Kansas. That move will take place later this year.

Fellow Cessnans,

Late yesterday, Textron released its financial results for the first quarter of the year. They reiterated, as we told you at the end of March, a continued decline in global demand for our aircraft, which in turn requires us to reduce our production rates for this year and next.

That also means a reduction in revenue that will require us to be very strategic in our investments to ensure the long-term success of Cessna.

Our primary near-term objective is to focus on our strengths and protect our core products in the light and mid-size business jet market segments, our leadership position in the single-engine piston and turboprop product segment, and our world-class customer support.

This strategy brings with it more hard decisions, but necessary in this trying economy.

To ensure our focus is on our strong products in existing markets, we are suspending our development of the Citation Columbus. This was a very difficult decision, but critical to sizing our business to the realities of today’s market. We looked at every possible scenario before coming to this decision. We still feel this is a program with great potential and one we will pursue when the market recovers.

Today, it is critically important to support the markets we compete in by strengthening our existing product line and support services. Our strategic investments will be in these areas. To that end, we will continue programs such as the Citation CJ4 and the 162 SkyCatcher.

We also will continue to work on research and development of numerous yet-to-be-announced new products, all of this while exploring new ways to strengthen our customer support offerings.

The reduced production rates, regrettably, require another reduction in the work force as I told you in my last memo a few weeks ago. We began today issuing layoff notices to approximately 1,600 Cessnans at every level of the company. As we have done in the past, these colleagues will remain on the payroll 60 days. As we re-evaluate our requirements in the coming weeks following the changes in our product development plans, we will issue additional layoff notices within the salaried work force – up to 700 – by mid-June. This sizes our work force for our currently planned production in 2010.

Quickly reducing the number of aircraft we produce is somewhat more involved than simply slowing our operations. It will require us to extend the planned companywide employee furlough to four weeks, running June 22 through July 19. This companywide furlough will coincide with various assembly line furloughs already instituted to match production to demand. This action is required to remove the aircraft and the associated costs from this year’s production schedule.

We will still have the people on duty we need to support customer deliveries, customer service and a few programs and operations that must continue uninterrupted. The rest of us are expected to take part in this furlough unless notified by your supervisor. Additional information regarding the furloughs will be shared soon.

A key part of our activity is cost reduction and that will include consolidation of facilities. We continue to look at a number of options, but some decisions have already been made. While very painful to share, we will be closing the facility in Bend and moving that assembly line to Independence. This is not a result of any dissatisfaction with the Bend operation, but is driven by the need to consolidate facilities for factory efficiency.

I will be meeting today with the Cessna Leadership Team to share details of the state of the market and the economy and of our plans to weather the downturn. They will, in turn, be cascading this information throughout the company in smaller meetings to continue to promote open dialogue through this difficult period.

There doesn’t seem to be a lot of good news for Cessna right now, but times will change. That does little to lessen the pain and disappointment brought on by what we’re all going through. For those employees who will be leaving Cessna, I want to thank you for your dedication and hard work. For those who will remain, we need to work together to ensure we continue the highest level of service to our customers, survive this economic recession, and prepare for the days when we begin to grow again.
