The Cooper-Harper Handling Qualities Rating Scale [1] (HQRS), sometimes Cooper-Harper Rating Scale (CHRS), is a pilot rating scale, a set of criteria used by test pilots and flight test engineers to evaluate the handling qualities of aircraft while performing a task during a flight test. The scale ranges from 1 to 10, with 1 indicating the best ...
The height information is represented as 11 binary digits in a parallel form using 11 separate lines designated D2 D4 A1 A2 A4 B1 B2 B4 C1 C2 C4. [3] As a twelfth bit, the Gillham code contains a D1 bit but this is unused and consequently set to zero in practical applications. Different classes of altitude encoder do not use all of the ...
The Degree (D) value has an almost linear dependence on the square root of the average wave Height (H) above, i.e., +. Using linear regression on the table above, the coefficients can be calculated for the low Height values ( λ L = 2.3236 , β L = 1.2551 {\textstyle \lambda _{L}=2.3236,\beta _{L}=1.2551} ) and for the high Height values ( λ H ...
F1 tornadoes on the Fujita scale and T2 TORRO scale also begin roughly at the end of level 12 of the Beaufort scale, but are independent scales, although the TORRO scale wind values are based on the 3/2 power law relating wind velocity to Beaufort force. [7] Wave heights in the scale are for conditions in the open ocean, not along the shore.
These figures should be compared with the temperature and density of Earth's atmosphere plotted at NRLMSISE-00, which shows the air density dropping from 1200 g/m 3 at sea level to 0.125 g/m 3 at 70 km, a factor of 9600, indicating an average scale height of 70 / ln(9600) = 7.64 km, consistent with the indicated average air temperature over ...
The Richter scale [1] (/ ˈ r ɪ k t ər /), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale".

The significant wave height H 1/3 — the mean wave height of the highest third of the waves. The mean wave period , T 1 . In addition to the short-term wave statistics presented above, long-term sea state statistics are often given as a joint frequency table of the significant wave height and the mean wave period.
The vertical exaggeration is given by: = where VS is the vertical scale and HS is the horizontal scale, both given as representative fractions.. For example, if 1 centimetre (0.39 in) vertically represents 200 metres (660 ft) and 1 centimetre (0.39 in) horizontally represents 4,000 metres (13,000 ft), the vertical exaggeration, 20×, is given by:
