The basic limitations were defined of the pilot plus rotorcraft in making the transition from a very low decision height to a steady hover over the helipad. The term 'decision-height window' is defined as the limits of glideslope/localizer tracking errors, and groundspeed variations, that can exist at breakout to allow a safe visual transition to hover. The dimensions of the decision-height window can have a significant impact on the required rotorcraft handling qualities, and for setting autopilot coupler and flight director performance standards for decelerating instrument approaches in rotorcraft.
