Not an airliner TCAS with TAs and RA alerts etc., but a much simpler, decluttered display showing only very local traffic that a pilot could look at just before lifting:
"Right, there is one just above me and to my right. Let's find him visually before I lift, or wait for him to pass first." - and reverting to standard eyes outside flying for the actual lift.
Maybe this is what the TAS system provides?
