  Chapter 4: Approaches › Minimum Descent Altitude (MDA), Decision Altitude (DA), And Decision Height (DH)

  Minimum Descent Altitude (MDA), Decision Altitude (DA), And Decision Height (DH) MDA—the lowest altitude, expressed in feet 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. DA—a specified altitude in the precision approach at which a missed approach must be initiated if the required visual reference to continue the approach has not been established. DH—with respect…

  intentions are. When the approach to be executed has been determined, the pilot should plan for and request a descent to the appropriate altitude prior to the initial approach fix (IAF) or transition route depicted on the IAP. When flying ... transition route, a pilot should maintain the last assigned altitude until ATC gives the instructions “cleared for the approach.” Lower altitudes can be requested to bring the transition route altitude closer to the required altitude at the initial approach…

  Guidance in elevation is not possible but the pilot will be advised when to commence descent to the Minimum Descent Altitude (MDA) or, if appropriate, to an intermediate step-down fix Minimum Crossing Altitude and subsequently to the prescribed MDA ... mile on final from the runway, airport or heliport or MAP, as appropriate. If requested by the pilot, recommended altitudes will be issued at each mile, based on the descent gradient established for the procedure, down to the last mile…

  Chapter 4: Approaches › Maximum Acceptable Descent Rates

  Descent Rates and Glidepaths for Nonprecision Approaches Maximum Acceptable Descent Rates Operational experience and research have shown that a descent rate of greater than approximately 1,000 fpm is unacceptable during the final stages of an approach (below ... human perceptual limitation that is independent of the type of airplane or helicopter. Therefore, the operational practices and techniques must ensure that descent rates greater than 1,000 fpm are not permitted in either the instrument or visual portions…
