Setting/Editing Hold and Buffer Altitudes
Altitude Assist features require that the system include an altitude
input device. The NMC alerts you when you’ve ascended/descended
into the Hold Buffer, or have strayed outside of the buffer. The Buffer
Altitude is the altitude above and below your Hold altitude at which
you want to be alerted with a message. This procedure is used to set the
Hold Altitude and the Buffer Altitude.
