If the Course Deviation Indicator (CDI) is greater than half scale deflection, the autopilot
will arm the VAPP 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.
In aircraft with a DG installed and no HSI, VAPP 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.
