2.32 PITOT-STATIC SYSTEM
The pitot-static pmssure system supplies impact (pitot)

instruments, to the CADC, and to the engine AICS programmers.

The pitot-static system is composed of two separate
systems with individual pitot-static probes, one on each
side of the forward fuselage.
The left pitot pressure (PT) probe supplies the pilot
standby airspeed indicator and the left AICS programmer.

The left and right forward static ports f&t) are manifolded
to provide static pressure to the pilot standby
airspeed indicator, standby altimeter, vertical speed indicator,
and the CADC. Static pressure from the right

l The RUDDER AUTH caution light may
illuminate when the in-flight refueling

RESET button to reset the light.
2.32.1 Pitot-Static Heat. Bach pitot-static probe is
equipped with electrical beating elements to prevent
icing. Pitot-static heat is controlled by the pilot through
the ANTI-ICE switch on the pilot right console. In
AUTO/OFF, pitot probe heat is available only with weight
off wheels. ORlDE/ON activates the probe heat elements
independently of the weight-on-wheels switch
and illuminates the INLET ICE caution light on the
CAUTION ADVISORY panel. OFF/OFF removes heat
Born the probes.
[-G&q
The ANTI-ICE switch should normally be
in AUTO/OFF during takeoff and landing.
Engine anti-icing has adverse effects on engine
stall margin.

2.33 CONTROL AND DISPLAY SYSTEM
The control and display system (Figure 2-83) provides
the crew with control and display of navigation,
aircraft status, and flight tactical information. The control
and displays system consists of two display processon
@PI and DP2), three multifunction displays @lot
center MFDI, pilot right MFD2, and RIO MFD3), and
a heads-up display system, cockpit television sensor,
HUD-VIDEO panel, pilot DISPLAYS control panel,
and a multistatus indicator.
The control and display system also sends display
information to the digital display, the radio tiequency
indicator, radio frequency/control indicator, and the
mission video recorder.
The data entry unit is a remote terminal that communicates
with the mission computers via the multiplex
buses.
2.33.1 Display Types. The following types of display
information are provided by the MFD system:
1. Calligraphic or stroke writing is displayed on the
HUD, MFDs, and the DD.
2. Raster video (for example radar, television) generated
internally (VDI formata) or provided by an
&ems1 sensor, with or without a stroke overlay,
is displayed on the MFDs and the DD.
3. Alphanumeric data is displayed on the multistatus
indicator and the radio f?equency and radio
