Can the Honeywell KTA-870 Traffic Advisory System be certified as TCAS I?
No. the KTA-870 System does not qualify as a TCAS I System. Although it has TCAS like symbology and specifications when displayed on an MFD, the system does not meet TSO C118 for TCAS I approval. Honeywell has released the KTA-970 and KMH-980 systems for TCAS I approval.
