  • Nord-Micro's TTP-Based Cabin Pressure Control System
    Advanced Control Systems for Airbus A380 Nord-Micro’s TTP-Based Cabin Pressure Control System More about this success story online www.tttech.com/aerospace We have decided for TTTech because our systems are critical for passenger safety and cabin comfort. Their time-triggered protocol TTP and products provide us with “ the safest and most advanced platform for cabin pressure control systems available on the market. Friedrich Scheerer Manager Cabin Pressure Control System Development Nord-Micro ” The Airbus A380 is the most advanced, spacious and efficient commercial airliner ever conceived. Designed in close collaboration with major airlines, airport operators and airworthiness authorities, the A380 brings new standards of cabin comfort and better economics in more environmentally responsible aircraft. Whilst doing all of this, it allows growth and reduced congestion from today’s airports with minimum change. Most importantly, the A380’s modern technology and economies of scale offer passengers a whole new way of flying and more affordable prices. The A380 flies for up to 14 hours at an altitude of 11,000 meters with an ambient temperature of -56°C and a pressure of less than 20 per cent of the usual ambient pressure. No human being could survive air travel in such a hostile environment. In order to ensure that passengers and attendants enjoy their flight under the same conditions as in daily life, a cabin pressure control system is required. Airbus selected Nord-Micro (Business unit of UTC Aerospace Systems), Frankfurt/Germany, to supply its highly reliable cabin pressure control system to the new flagship of their fleet.

Much of the published lean literature is written at a high level of abstraction and contains very basic examples. When lean tools are applied blindly to complex, highly constrained systems, lean implementation becomes challenging and often ineffective.
