  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…

  These instrument procedures may be designed to guide the helicopter to a specific landing area (Proceed Visually) or to a point-in-space with a “Proceed VFR” segment. 1. An approach to a specific landing area. This type of approach ... missed approach point from which a landing can be accomplished with a maximum course change of 30 degrees. The visual segment from the MAP to the landing area is evaluated for obstacle hazards. These procedures are annotated: “PROCEED VISUALLY FROM…

  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…

  Emergency Medical Service (EMS) Multiple Helicopter Operations a. Background. EMS helicopter operators often overlap other EMS operator areas. Standardized procedures can enhance the safety of operating multiple helicopters to landing zones (LZs) and to hospital heliports. Communication ... successful operations and in maintaining organization between helicopters, ground units and communication centers. EMS helicopter operators which operate in the same areas should establish joint operating procedures and provide them to related agencies. b. Recommended Procedures. 1. Landing Zone Operations…
