AIR DATA SYSTEM (Cont)
ALTIMETER BAROMETER KNOB
The ALTM BARO knob is rotated to increase or decrease barometric pressure setting. The barometric setting is displayed
on the PFD. The standard barometric pressure setting of 29.92 inches of mercury, or 1013 hPa, is selected when the center
of the BARO knob is pressed.
AIR DATA REVERSION SWITCH
The AIR DATA switch is located on the reversion panel on the center pedestal. When NORM is selected, the pilot’s and
copilot’s adaptive flight displays receive data from their respective air data computer (ADC).
When ‘1’ is selected, the pilot’s and copilot’s adaptive flight displays receive data from ADC 1 only. An amber ADC 1
message is displayed on both PFDs.
When ‘2’ is selected, the pilot’s and copilot’s adaptive flight displays receive data from ADC 2 only. An amber ADC 2
message is displayed on both PFDs.
AIR DATA COMPUTERS
Each ADC senses total pressure, static pressure, and total temperature. The pressure sensors are solid-state piezoresistive
type, and transform the pressure to an analog electrical signal. The analog signal is then digitized and used for all ADC
calculations. Data is then passed from the ADCs to the cockpit displays, IAPS, other aircraft systems.
The ADC calculates the following air data parameters:
- Pressure altitude
- Static pressure
- Total pressure
- Vertical speed
- Airspeed
- Mach number
- Maximum airspeed (V
MO
)/maximum mach number (M
MO
)
- Baro correction
- Barometric corrected altitude
- Static air temperature
- Total air temperature
- True AIRSPEED
- Temperature difference from standard (ISA)
