3.9.1 Live Data - Discrete Inputs, Altitude, and Heading
1. From the MPC (MAT) select Service > Live Data > Discrete Inputs, Altitude, and Heading. An
example of this page is shown in Figure 3-16.
• Review the information seen on the inputs page.
• The Audio Ack In Active discrete input is available only using the MPC (MAT) 8010-17002-020x
or 8010-17002-030x.
• The True/False indication of the current state of the discrete (e.g., True for the squat on ground
means that the aircraft is on ground. A false would mean that the aircraft was not on the ground,
at least according to the discrete).
Note – when the audio mute discrete is grounded, it is considered active l (i.e. muted). The
Audio Mute In active indication shows "True" when this discrete is active (grounded).
• The Overall Discretes Validity is an indication of the remaining discrete states. A "True"
indicating that these indications are valid. A "False" indication with red text indicates that the
input is not being detected by the unit and a problem exists. If a problem is noted, do the
following.
o Check the configuration setup options for correct settings.
o Check the fault log (Info > Fault Log) for issues.
o Check wiring or equipment.
• Compare the altitude and heading values to an outside source.
