Meaning of minimum descent altitude | Babel Free

Definitions

The lowest altitude at which an aircraft is permitted to fly during a non-precision approach without the runway being in clear sight.

Examples

“The National Transportation Safety Board determines that the probable cause of this accident was the descent below Minimum Descent Altitude during a nonprecision approach under adverse operating conditions, without visual contact with the runway environment. The Board has been unable to determine the reason for this descent, although the two most likely explanations are (a) improper use of cockpit instrumentation data, or (b) an altimetry system error.”
