• Heading and Airspeed
o Heading and airspeed information can optionally be sent in to the MXS. If this is done the
guidance in AC 20-165B must be followed.
• Altitude Rate
o Altitude rate (vertical rate) source should be sent in to the MXS following the guidance of
AC 20-165B. If vertical rate is sent through the operating message, then the MXS uses that
rate otherwise the GPS vertical rate is used.
