7.11 - Air data system and instruments
- see figure 7.11.1
The airplane air data system consists of :
-
Primary systems :
-
two separate static pressure systems,
-
two separate dynamic pressure systems.
-
An alternate static pressure system.
Static pressure systems
Primary systems
Two dual static ports (one on each side of the fuselage tail section) supply a dual
system routed to the cockpit.
Static system 1 supplies :
-
ADC 1
-
the standby instrument
,
through the Normal / Alternate static source switching
valve, when the ALTERNATE STATIC SOURCE selector is in the Normal
position (pushed). The ALTERNATE STATIC SOURCE selector is located on
the instrument panel under the right-side control wheel.
Static system 2 supplies ADC 2.
Each line has a drain plug located under the instrument panel on the right side.
Alternate static source
The alternate static port, located inside the rear fuselage, supplies a line routed to the
Normal / Alternate static source switching valve.
If a false airspeed indication or primary static system failure is suspected, the pilot can
pull the ALTERNATE STATIC SOURCE selector fully out to select the alternate static
source. In that case, static pressure from the alternate line is only provided to the
standby instrument. Static pressure from the alternate line is not provided to either
ADC.
▲
CAUTION
▲
Do not rely on PFD indications when the alternate static source is
selected. Only refer to the standby instrument for airspeed and altitude.
▲
The alternate line has a drain plug located under the instrument panel on the right side.
