If HSI is installed:
4.
Intercept Heading ....................................................ESTABLISH in HDG or ROL mode (if required)
If DG is installed (no HSI):
4. Approach Course ..........................................ALIGN aircraft on approach course using HDG mode

6. Bold or subdued font GPS and GP annunciations ..................................................VERIFY on GMC 605
If GPS roll steering capability is not installed (see installed features checklist):
7. During course changes over 30°, SELECT HDG mode to manually track the desired course.
SELECT APR mode once the aircraft is established on the new course.
8. Vertical Mode and Reference……………………….………………………………. SELECT on GMC 605
If required for GPS approach without vertical guidance
9. Airspeed
.........................................................................MAINTAIN 90 KIAS or greater (recommended)
NOTE
If the Course Deviation Indicator (CDI) is greater than half scale deflection, the autopilot
will arm the GPS mode. The pilot must ensure that the current heading will result in a
capture of the selected course. If the CDI is within half scale deflection, the autopilot will
enter the capture mode when the APR key is pressed.
When the selected GPS approach includes vertical guidance (LPV, LNAV/VNAV,
LNAV+V, LP+V), glidepath coupling is automatically armed when the APR key is
pressed. The glidepath cannot be captured until the lateral approach path is captured.
The autopilot can capture the glidepath from above or below the glidepath.
In aircraft with a DG installed and no HSI, GPS mode cannot be armed. HDG mode must
be used to align the aircraft on the approach course with less than half scale deflection
prior to pressing the APR key.
