Table schema:
CREATE TABLE Other_Available_Features (feature_type_code VARCHAR, feature_name VARCHAR); CREATE TABLE Ref_Feature_Types (feature_type_name VARCHAR, feature_type_code VARCHAR)

Question: What is the feature type name of feature AirCon?
SQL: SELECT T2.feature_type_name FROM Other_Available_Features AS T1 JOIN Ref_Feature_Types AS T2 ON T1.feature_type_code = T2.feature_type_code WHERE T1.feature_name = "AirCon"
