Section 14. Primary Flight Display (PFD)
Indications & Loss of Signal
The CDI moves relative to the course selection arrow to indicate course
deviation. When the course deviation is zero, the CDI is green and aligned with
the rest of the course selection arrow, centered on the horizontal scale. When
the intended course is to the left or right of the current aircraft position, the CDI
displaces accordingly. If the deviation is greater than full scale, the deviation bar
turns amber. If navigation signal is interrupted or intermittent, the TO/FROM flag
and the needle disappear.
Scale
VOR — When a VOR station is selected as primary navigation source, the CDI
indicates the course deviation in degrees with a full scale of range of 10 degrees
left or right.
Localizer — When a localizer is the primary navigation source, the CDI indicates
localizer deviation in degrees with a full scale range of 2.5 degrees left or right.
FMS — When the FMS is the primary navigation reference full scale deflection is
dependent upon the current navigation mode.
The "TO/FROM" indicator for VOR navigation is a single arrowhead located in the
center of the HSI. The arrowhead points TO the station if the bearing to the
station differs from the selected course by less than 90 degrees, and points
FROM the station when the bearing to the station differs from the selected course
by more than 90 degrees.
Radio Magnetic Indicator (RMI)
The blue dual-line bearing pointer corresponds to the BRG line select key on the
PFD. When selected to an FMS or VLOC frequency, the RMI arrowhead points
to the current selected course of the primary navigation source. The bearing
pointer is not displayed if the VLOC source is tuned to an ILS or LOC station.
