7.11 -- AIR DATA SYSTEM AND INSTRUMENTS
(Figure 7.11.1)
Airplane air data system consists of :
-- two separate static pressure systems supplying an altimeter, an airspeed
indicator and air data computers (ADC).
A part of system 1 is backed up by an alternate system which operation is
controlled by a switching valve (normal / alternate) attached to instrument
panel under R.H. control wheel. In case of obstruction or icing of ports, this
selector isolates airplane normal static system. When selector is on
alternate position (pulled rearwards), static pressure is picked from a port
located in airplane rear fuselage.
-- two separate dynamic pressure systems supplying the airspeed indicator
system and air data computers.
STATIC PRESSURE SYSTEMS
Primary systems
Two dual static ports (one on either side of the fuselage tail part) supply a dual
system routed towards the cockpit.
System 1 part, which is connected to the switching valve (normal / alternate),
supplies the altimeter, the
∆
P cabin and the airspeed indicator. The system
remainder directly supplies one of the air data computers.
System 2 is directly connected to the second ADC.
Systems feature a drain valve located under the instrument panel on R.H.
side.
