ACS element text (the applicant demonstrates understanding of)

Assess factors related to the environment (weather, airports, terrain, airspace).

Bottom line

To avoid terrain and obstacles, especially at night or in low visibility, determine safe altitudes in advance by using the altitudes shown on VFR and IFR charts during preflight planning. Use maximum elevation figures (MEFs) and other easily obtainable data to minimize chances of an inflight collision with terrain or obstacles.
