AIR DATA SYSTEM (ADS)

The air data system and air data instruments depend upon pitot pres-
sure and static pressure sensing, as well as air temperature sensing. Air
data is provided to the flight instruments and airplane systems by two
Air Data Computers (ADCs) which receive pitot and static information
from the main pitot static system. The ADCs receive total air tempera-
ture from a dual element temperature probe and barometric correction
inputs via the BARO set knobs on the corresponding PFDs.

PITOT-STATIC SYSTEM

The primary pitot-static system consists of two pitot-static probes, lo-
cated one on each side of the airplane's nose section. The pilot's pitot-
static probe supplies the pilot's ADC with total pressure and the copi-
lot's pitot-static probe supplies the copilot's ADC with total pressure.
Each pitot-static probe has two isolated static ports. The pilot's ADC re-
ceives static pressure from coupled static ports off the pilot's and copi-
lot's pitot-static probes (Figure 5-7). The copilot's ADC receives static
pressure from separate coupled static ports off the pilot's and copilot's
pitot-static probes which are isolated from the static ports used by the
pilot's ADC.
