A minimum off-route altitude (MORA) provides a quick way for an aircraft pilot to read the minimum altitude required for terrain and obstacle clearance. MORAs give at least 1,000 feet altitude clearance above terrain and obstacles such as radio masts, and 2,000 feet where the terrain and obstacles exceed 5,000 feet. [1]
The 2 mile (3,520 yards, [1] 10,560 feet, or exactly 3,218.688 metres) is a historic running distance. Like the mile run, it is still contested at some invitational meets due its historical chronology in the United States and United Kingdom.
They then progressed to the "faster step" or "full pace" [3] and were required to complete 24 Roman miles (35.544 km or 22.086 modern miles) in five summer hours loaded with 20.5 kilograms (45 lb). Training also included some forced marches of 20–30 miles, often followed by the construction of basic defences for an overnight position.

The United States march command is "For-ward, MARCH," or "quick time, MARCH" when resuming quick time from another pace or from "route step". Arm movement is kept to 9 inches to the front and 6 inches to the rear (6 inches and 3 inches, respectively, in the U.S. Navy, Coast Guard, Marine Corps, and Air Force) while marching, while the interval ...
Many people tend to walk at about 1.42 metres per second (5.1 km/h; 3.2 mph; 4.7 ft/s). [ 1 ] [ 2 ] [ 3 ] Individuals may find slower or faster speeds uncomfortable. Horses have also demonstrated normal, narrow distributions of preferred walking speed within a given gait , which suggests that the process of speed selection may follow similar ...
In aviation, a flight level (FL) is an aircraft's altitude as determined by a pressure altimeter using the International Standard Atmosphere. It is expressed in hundreds of feet or metres. The altimeter setting used is the ISA sea level pressure of 1013 hPa or 29.92 inHg. The actual surface pressure will vary from this at different locations ...
From 1630 to 1718 a millia was 5,564 feet (1,696 metres), making a geographical league of four millias equal 22,256 feet (6,784 m or 3.663 modern nautical miles). But from 1718 through the 1830s the millia was defined as the equivalent of just over 5,210 feet, giving a shorter geographical league of just over 20,842 feet (6,353 m or 3.430 ...
