VFR Cruising Altitude Rules in The US
In the US, there are specific VFR cruising altitudes, based on the aircraft's heading, to assist pilots in separating their aircraft while operating under visual flight above 3,000 ft but below 18,000 ft Mean Sea Level (MSL). Unofficially, most pilots use these rules at all levels of cruise flight. FAR 91.159 states that any aircraft:
- On a magnetic course of 0-179 degrees shall fly at an odd thousand ft MSL altitude +500 feet (e.g. 3,500, 5,500, or 7,500 ft); or
- On a magnetic course of 180-359 degrees shall fly at an even thousand ft MSL altitude +500 feet (e.g. 4,500, 6,500, or 8,500 ft).

Famous quotes containing the words cruising, altitude and/or rules:
“I’ve given parties that have made Indian rajahs green with envy. I’ve had prima donnas break $10,000 engagements to come to my smallest dinners. When you were still playing button back in Ohio, I entertained on a cruising trip that was so much fun that I had to sink my yacht to make my guests go home.”
—F. Scott Fitzgerald (1896–1940)
“On a level plain, simple mounds look like hills; and the insipid flatness of our present bourgeoisie is to be measured by the altitude of its “great intellects.””
—Karl Marx (1818–1883)
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
