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:
“The admission of Oriental immigrants who cannot be amalgamated with our people has been made the subject either of prohibitory clauses in our treaties and statutes or of strict administrative regulations secured by diplomatic negotiations. I sincerely hope that we may continue to minimize the evils likely to arise from such immigration without unnecessary friction and by mutual concessions between self-respecting governments.”
—William Howard Taft (1857–1930)
“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)
