Approach Captured will be displayed when this transition occurs and the GPS CDI and course indicator will then be driven by the synthetic approach as well as the autopilot If capture of the synthetic approach is attempted close to the runway the GRT Sport will try to predict when it must begin turning onto the synthetic approach course based on groundspeed and intercept angle so that it does not overshoot the course Since the response of the autopilot and airplane can not be predicted perfectly overshoot is possible and some loss of accuracy in the initial tracking of the synthetic approach may be expected The following diagram illustrates the synthetic approach capture criteria Rev C After synthetic approach glideslope capture the MISSED softkey will appear on the PFD screen Press this button and set engine power to full to execute a missed approach 2 5 degrees 2 5 degrees Capturing the synthetic approach emulates capturing a localizer and If the SAis ARMed close to the runway capture may occur earlier than expected This occurs because the EFIS tries to predict when the turn must be started in order to capture the SA course Depending on the direction of travel and speed this can result in capture that begins well outside of 2 5 degrees from the inbound course can be performed up to 20 nm from the runway Typically the synthetic approach will be captured when within
