TCAS TAonly in high altitude cruise
Hi,
my company soon will add minor changes to the existing SOP, one of this changes is to set the TCAS on TAonly during high altitude cruise, because of the net ceiling of the plane doesn't allow any eventual CLIMB RESOLUTION.
They said that on the airbus fleet it is a manufacturer standard operation, therefore with the aim of improve standardization on the whole airline we should perform this practice on any other jet.
what do you think?
I'm gonna say that this is totally unsafe,
what if you are cruising at fl380, converging traffic both on TA only no one will ever get any resolution; but probably both pilot will think that at least the other aircraft will get a ANY RESOLUTIVE command.
if both are in RA one for sure will get a descent and will start to descent and the other will get a climb, then even if the performances are really bad, for sure it will increase the clearance in beetween!!
