US Regulations
In the United States, most controlled airspace below 10,000 ft (3,000 m). MSL requires a pilot flying under VFR to remain 500 ft (150 m). below a cloud ceiling and to maintain 3 statute miles (4.8 km) visibility. However, outside of airport control zones and major terminal areas, controlled airspace typically begins at 1,200 feet (370 m) above ground level; below that is uncontrolled (class G) airspace, where (at that altitude) a pilot is required only to remain clear of clouds and to maintain 1 statute mile (1.6 km) visibility.

Famous quotes containing the word regulations:
“If it were possible to make an accurate calculation of the evils which police regulations occasion, and of those which they prevent, the number of the former would, in all cases, exceed that of the latter.”
—Karl Wilhelm Von Humboldt (1767–1835)
“If the veil were withdrawn from the sanctuary of domestic life, and man could look upon the fear, the loathing, the detestations which his tyranny and reckless gratification of self has caused to take the place of confiding love, which placed a woman in his power, he would shudder at the hideous wrong of the present regulations of the domestic abode.”
—Lydia Jane Pierson, U.S. women’s rights activist and corresponding editor of The Woman’s Advocate. The Woman’s Advocate, represented in The Lily, pp. 117-8 (1855-1858 or 1860)
