Since we usually cant see unlit objects at night, theres an increased risk of controlled flight into terrain, CFIT, and the plain, old-fashioned collision with an obstacle. One way to help minimize the risk of CFIT at night is simple: fly higher. And one way to do that is use IFR minimum altitudes even when VFR.
Night flying significantly increases the risk of controlled flight into terrain (CFIT) and obstacle collisions due to poor visibility.
To minimize this risk, pilots should fly at higher altitudes, specifically recommending the use of IFR minimums like the Off Route Obstruction Clearance Altitude (OROCA) even when flying VFR.
OROCA provides a greater safety buffer (1000-2000 feet) than the Maximum Elevation Figure (MEF), offering a critical margin against terrain and potential altitude loss during emergencies.
