7.11 -- AIR DATA SYSTEMS AND INSTRUMENTS
Airplane air data system consists of :
-- two separate static pressure systems supplying a standby attitude module
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 standby attitude
module 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
∆
P cabin and the standby attitude module. 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.
Alternate static source
The alternate static port located in the rear fuselage supplies a system routed
to the switching valve (normal / alternate) in order to replace static system 1.
The alternate line incorporates a drain plug located under the instrument
panel on R.H. side.
DYNAMIC PRESSURE SYSTEM
One heated pitot probe is installed under the L.H. wing. The second one is
installed under the R.H. wing. The first one supplies the standby attitude
module and one ADC.
The second one supplies the other ADC.
Both lines incorporate a drain plug located in the root of L.H. and R.H. wings.
