b. TCAS II can only be fitted to large aircrafts which carry more than 30 passengers. While TCAS I can be fitted to any aircraft.
c. TCAS I can be fitted aircrafts which carry transponders with Mode A only while TCAS II can be fitted to aircrafts whose transponders include either Mode C or Mode S. d. TCAS II can only be to aircraft which are equipped with EFIS
