I just read an interesting short article about an incident on a Condor A320.
The airplane was climbing out of Kavala (Greece) on August 16, 2018 when a TCAS warning was received. The pilots were instructed to climb and they followed that instruction. Shortly after, the TCAS warning changed and the pilots were instructed to descend. Again, they did as instructed.
That descend did result in a TAWS terrain warning though and the pilots were forced to initiate a terrain escape maneuver.
That must have been one hell of a confusion. First a TCAS climb, then a TCAS descend and then a TAWS. And everything shortly after departure.
Here’s the link to the article:
The incident is under investigation. I’m sure the results will be pretty interesting.
