AIR DATA AND SENSORS ANTI-ICE
DESCRIPTION
The air data probes and sensors are located on either side of the aircraft nose and are electrically heated to prevent ice for-
mation. Separate air data sensor heat controllers provide control and monitoring of the probe heaters.
L (R) PROBES switches are provided on the ANTI-ICE control panel. When selected On, the following probes and sensors
are heated:
- Left and right standby static port
- Left and right AOA sensor
- Left and right pitot-static probe
- TAT probe
- Standby pitot probe
Failure of a probe heater will signal the DCU to display the appropriate EICAS message.
COMPONENTS AND OPERATION
PITOT STATIC PROBES
There are two pitot static masts, one on either side of the nose. The pitot static mast consists of a head and mounting base.
The mast has two heaters, one in the head and the other in the base.
STANDBY PITOT PROBE
There is one standby pitot probe on the left side of the nose.
STANDBY STATIC PORTS
One flush standby static port located in each side of the aircraft.
ANGLE-OF-ATTACK VANES (AOA)
Angle-of-attack vanes are located on each side of the aircraft under the side windows and behind the pitot tubes. The AOA
vanes are heated when activated by the PROBES switch.
TOTAL AIR TEMPERATURE PROBE (TAT)
One total air temperature sensor is located in the right side of the aircraft. The TAT heater operates in flight only.
