KING AIR C90GTi/C90GTx PILOT TRAINING MANUAL
FOR TRAINING PURPOSES ONLY
16-21
RADAR Button
The RADAR button displays the weather
radar menus on the PFD. See the Weather sec-
tion of this manual.
GCS Button
The GCS button controls the ground clutter
suppression selection of the weather radar. See
the Weather section of this manual.
TILT Control
The TILT knob controls the weather radar an-
tenna tilt angle. See the Weather section of this
manual.
RANGE Knob
The RANGE knob controls the display range
shown on the PPOS map, North-up Planning
Map, and TCAS only Display. The selected
range annunciations are shown on the PFD
and MFD as discussed above.
INTEGRATED AVIONICS
PROCESSOR SYSTEM
(IAPS)
The Integrated Avionics Processor System
(IAPS) provides system integration and oper-
ating logic for most systems that make up the
Pro Line 21 avionics. This unit is installed in
the nose of the aircraft in the avionics bay (Fig-
ure 16-42). It consists of two sections; the No.
1 (left) section monitors the No. 1 aircraft sys-
tems while the No. 2 (right) section monitors
the No. 2 systems. Each section is powered by
a dedicated power supply. Fans control the
temperature of each unit to eliminate sus-
tained overheating which would cause an au-
tomatic shutdown of the respective power
supply. Additionally, the power supply opera-
tion is inhibited in extreme cold temperatures
below –40°C.
Each IAPS section contains the Flight Guid-
ance Computers (FGC’s) and the Flight Man-
agement Computers (FMC’s) for the
respective side.

AIR DATA COMPUTERS
(ADC)
Two digital Air Data Computers (ADC 1 and
ADC 2) convert raw dynamic flight data into
electronic signals for use by various airplane
systems (Figure 16-43). Both ADC’s are in the
nose of the aircraft in the avionics bay. The
ADC’s generate independently and are sup-
plied with the following inputs:
• Ram air pressure from the onside pitot
mast
• Static pressure from the static ports
• Air tempe rature
Each ADC supplies its onside systems (the
MFD is supplied from ADC 1). Reversionary
switching allows use of the cross-side ADC as
a backup. In the reversionary ADC mode, the
selected ADC supplies all systems.
Each ADC processes the data and provides
electronic signals to the following systems and
components:
