When aircraft manufacturers started to install just two seats instead of three in airliner cockpits in the 1980s, this was something of a mini-revolution. Since that time, planes have generally been flown by just the pilot and co-pilot.

Is an electrical stress test that typically employs voltage and/or temperature to accelerate the appearance of latent reliability defects in a device. The objective of burn-in is to eliminate all potential failure likely to occur at the early phase of the product life time (also called Infant Mortality Failure). It can easily be observed in a typical reliability bath tub curve as shown below.

When developing mission-critical space applications such as low Earth orbit (LEO) satellites or equipment designed for Mars missions, there are special considerations you must make if you will be operating your RF circuits in a vacuum. This is because when the pressure in the vacuum is below 10-2 Torr, a potentially catastrophic phenomenon in RF circuits called multipaction is possible.

Product durability and accelerated life cycle testing are all methods of determining the reliability of a product before release. By subjecting the capacitor to elevated conditions far beyond its normal operational ranges, we seek to discover any defects or points of failure to better inform customers about the limitations of the unit.

Life test is an electrical stress test that typically employs voltage and/or temperature to accelerate the appearance of wear-out reliability failures in a device. The objective of life testing is to evaluate whether failures caused by wear-out are likely to occur during the product lifetime and thus to estimate compliance of the device with the long-term reliability requirements

The space probe Rosetta was built by the European Space Agency (ESA ) with the objective of reach and study Comet 67P/Churyumov-Gerasimenko. Was launched on March 2004 from Kourou. To place it on the required orbit to rendezvous with Comet 67P/ Churyumov-Gerasimenko it received four gravity assist manoeuvres: 3 from Earth (4 March 2005, 13 November 2007 and 13 November 2009) and 1 from Mars (25 February 2007).
