Except when necessary for takeoff or landing, what is the minimum safe altitude for a pilot to operate an aircraft?
An altitude of 500 feet above the highest obstacle within a horizontal radius of 1,000 feet.
Altimeter setting is the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates
true altitude at field elevation.
Unless otherwise authorized, what is the maximum indicated airspeed at which a person may operate an aircraft below 10,000 feet MSL?
250 knots.
