The question
Can a separation gate account for uncertainty in a craft’s own height, rather than trusting the reported level?
The flight
The LINK track introduced own-height error and tested declared allowances at the existing crossing. It compared communication tiers and diagnostic changes to the gate that decides whether craft in different bands need to avoid each other.
What happened
In this model, small declared vertical allowances of 1–2 m can protect the crossing. Larger allowances at the honest error dose can collapse the constrained crossing into wall losses. The earlier experiments also found that stale messages could accidentally trigger avoidance that a better link did not trigger.
What this does not establish
This is a result about the implemented gate and this corridor geometry. It is not evidence that worse communication is generally preferable, or that reporting uncertainty is generally harmful.
The next question
The problem now includes where the avoidance command sends the craft, not just whether the separation gate opens.
