ADAPTIVE FLIGHT DISPLAYS
(AFD)
The liquid crystal (LCD) Adaptive Flight
Displays (AFD) contain all the flight and
navigation information previously indicated
on separate “round dial” instruments. Three
AFD’s are installed in the King Air
C90GTi/
C90GTx
. The left and right AFD’s are inter-
changeable. The center AFD carries a differ-
ent part number to support more advanced
graphic capabilities and is not interchange-
able. The left AFD functions as the pilot’s
Primary Flight Display (PFD 1) on which air-
plane attitude, heading, altitude, vertical
speed, etc., are shown. The center AFD func-
tions as the multifunction display (MFD) on
which engine indications, diagnostic pages,
checklists, navigation data, etc. are shown.
The MFD receives much of the same data as
PFD 1. The right AFD functions as the copi-
lot’s Primary Flight Display (PFD 2) and op-
erates independent of PFD 1.
The temperature of LCD displays must stay
within appropriate limits to provide normal
operation. Should these temperature extremes
be exceeded each AFD has its own tempera-
ture monitor. Depending on what is needed
this monitor has control of integral heaters
and cooling fans.
In the event of a display failure on PFD 1 the
MFD can display PFD 1 images in what’s called
a reversionary or composite mode. However,
there is no reversionary backup to PFD 2.
Primary Flight Display (PFD)
The PFD displays airplane attitude and dy-
namic flight data. Flight Director indications,
autopilot annunciations, and navigation infor-
mation are also shown in a centralized loca-
tion including reversionary format. See typical
PFD display in Figure 16-2.
The PFD has the following controls and indi-
cations:
BRT/DIM Rocker Switch
The PILOT DISPLAYS rheostat, on the over-
head panel, provides primary intensity con-
trol. The BRT/DIM Rocker Switch on the
