A TA is a prediction that another aircraft will enter the conflict airspace in 25 to 45 seconds.




An RA is a prediction that another airplane will enter the TCAS conflict airspace within approximately 20 to 30 seconds. If altitude data from the other airplane is not available, no RA can be provided.

If the traffic airplane also has TCAS and a mode S transponder, TCAS vertical guidance is coordinated with the traffic aircraft TCAS.
