In that same era on a 777-200 the report from the tower or the cabin crew meant that the aircraft had to return. This was down to geometry - it is not possible to strike the tail without a warning in the 300 but it was in the 200.
This was later changed to be more conservative for both models.
Exactly as Dropp wrote.
Refer also to the latest 5G directive and the possible effects on the Tailskid system on the Tripple. If the caution is expected to be erroneous, one continues normal operation…Enough said.
