Is a temperature probe interface required for TAWS installations?
Most TAWS product manufacturers strongly recommend that a temperature input be used with terrain awarenss installations. Commonly, this input is only considered for aircraft operating in extreme weather conditions which may cause discrepancies in altitude calculations. The temperature input into TAWS provides a more accurate vertical position and prevents serious discrepancies between actual altitude and TAWS calculated altitude (i.e. &Geometric&) under extreme temperature conditions especially during rapid climbing or descending flight plans. Note: Most TAWS products (i.e. Bendix/King KGP series) consdier the temperature input an option. However, the temperaure input is required for the L3/Goodrich Landmark TAWS 8000 system. This input can be derived from a compatible air data computer or a independent temperature probe kit.
