§ 91.119 Minimum safe altitudes: General.
Except when necessary for takeoff or landing, no
person may operate an
aircraft below the following altitudes:
(a) Anywhere. An altitude allowing, if a power unit fails, an emergency landing without undue hazard to
persons or property on the surface. Not a factor
(b) Over congested areas. Over any congested area of a city, town, or settlement, or over any open air assembly of persons, an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the
aircraft. Not a factor at this location.
(c) Over other than congested areas. An altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the
aircraft may not be operated closer than 500 feet to any
person, vessel, vehicle, or structure. Applicable - A population is the total number of inhabitants. The airport population is probably zero.
