Exemptions
It is quite common for aircraft on delivery to be granted exemptions from carrying items like fully functioning TCAS and even transponders. If you don't have a transponder and rely on pressure altimeter (set to departure QNH instead of 1013.2) then TCAS on the other a/c has no chance. BTW, QNE is not a pressure setting (earlier post), it is the flight level equivalent of altitude at very high airports.
