E 5.3.2 CATEGORY 2, AIR DATA INPUT SELECT
The following table provides identification of the Air Data source type. The entry in the Air Data Type corresponds to a
table that provides detailed information on the configuration. For example, the details for Air Data Type #2 are found in
Table E 3.1.2. In this category, only the following signals are defined:
•
Uncorrected Barometric Altitude in analog and/or RS-422 or ARINC 429 format, and associated validity.
•
Temperature (Outside Air or Static Air) in analog or ARINC 429 format.
•
Corrected Barometric Altitude in ARINC 429 format.
•
Barometric Rate in ARINC 429 format.
•
Computed Airspeed in ARINC 429 format.

Note 1: The AZ-800 provides an OAT signal with reference provided by the ADC. This is not compatible with the EGPWS
interface. The AZ-241 provides no OAT interface. The customer may either add an additional OAT probe (ID 11) or use the
internal constant (ID 12). ID 11 is to be recommended in operations in temperature extremes.
