The rule affected only those aircraft operating under IFR when in level flight above 3,000 ft above mean sea level, or above the appropriate transition altitude, whichever is the higher, and when below FL195 (19,500 ft above the 1013.2 hPa datum in the UK, or with the altimeter set according to the system published by the competent authority in ...
The imperial nautical mile of 6080 feet (1853.19 m) was also formerly used by the Japanese in maritime contexts as a "marine ri". [14] A fourth and shorter ri of about 600 m is still evident in some beach names. The "99-Ri" beach at Kujukuri is about 60 km. The "7-Ri" beach at Shichiri is 4.2 km long.

All other railways use 1,668 mm (5 ft 5 + 21 ⁄ 32 in) (broad gauge); some use 1,000 mm (3 ft 3 + 3 ⁄ 8 in) metre gauge; Decauville uses 500 mm (19 + 3 ⁄ 4 in) gauge. Planned and under construction high-speed railways to use 1,668 mm ( 5 ft 5 + 21 ⁄ 32 in ) to maintain interoperability with the rest of the network.
