If the Course Deviation Indicator (CDI) is greater than half scale deflection, the autopilot
will arm the LOC 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 navigation source is an ILS, glideslope coupling is automatically
armed when the APR key is pressed. The glideslope cannot be captured until the localizer
is captured. The autopilot can capture the glideslope from above or below the glideslope.
