Note: Some material in this document has been updated from the original.

A common goal for all instrument approaches is to get the pilot (and the aircraft) into a position from where a normal landing can be made, usually with visual references.

The Aeronautical Information Manual) (AIM) defines minimum descent altitude, or MDA, as "the lowest altitude, expressed in feet above mean sea level (MSL), to which descent is authorized on final approach, or during circle-to-land maneuvering, in execution of a standard instrument approach procedure (SIAP) where no electronic glideslope is provided."

The AIM defines decision height, or DH, as "height at which a decision must be made during an instrument landing system (ILS), microwave landing system (MLS), or precision approach radar (PAR) instrument approach to either continue the approach or to execute a missed approach."

This pamphlet is designed to give you some helpful hints and tips to get you safely to the MDA or DH and beyond.
