1. (1) Determine the minimum safe cruise altitude by evaluating the terrain and obstacles along the planned route of flight;
2. (2) Identify and document the highest obstacle along the planned route of flight; and
3. (3) Using the minimum safe cruise altitudes in paragraphs (b)(1)-(2) of this section, determine the minimum required ceiling and visibility to conduct the planned flight by applying the weather minimums appropriate to the class of airspace for the planned flight.

(b) Enroute. While conducting VFR operations, the pilot in command must ensure that all terrain and obstacles along the route of flight are cleared vertically by no less than the following:

1. (1) 300 feet for day operations.
