To achieve certification in December 2020 and first delivery in 2021, the planned 4,200 h of flight tests would need 33 hours a month each if the last four prototypes are evenly spaced before year-end-2019. Newest airliner designs like the Airbus A350 needed a 2,600 hour test program, and the Mitsubishi MRJ was expected to need 3,000 h. [49]

In 1947, the exchange was renamed the Minneapolis Grain Exchange. Today the exchange is most recognized by its logo and uses MGEX as first reference.

With the falling number test, so-called weather- or sprout-damaged wheat or rye, which adversely affects bread-making quality, could be detected at the grain silo intake within a few minutes. Sprouting , or pre-harvest germination , is caused by damp or rainy weather conditions during the final stage of maturation of the crop.
Test weight refers to the average weight of a cereal as measured in pounds per bushel (1bu. = 8 gallons or 2150.42 cu. inches). Test weight is an important predictor of milling yield for rice and flour extraction rate for wheat. USDA’s official weight per bushel for the highest grade for major cereals and oilseeds include: wheat and soybeans ...
It is an indicator of general grain quality and primary grain specification: normally, a higher the test weight corresponds to higher quality, and lower test weight corresponds to lower quality, as grain quality decreases dramatically as grain deteriorates. [2] Test weight of grain is affected by many factors, including moisture contents ...
Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials . This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.
50 g of air dried coal featuring a grain size in the range between 0.6 and 1.18 mm are filled into the sample mill and a weight is put on the mill's grinding stone. After 60 rounds the grinded coal is put on a sampling sieve. Factor D equals the fraction of the coal passing through the sieve of 74 μm corresponding to 200 mesh.
