It would be '
inefficient' to close a thread because of boredom without at least some understanding of why … boredom, efficiency, safety in operations.
Differences in views should be expected - life; the value in these differences is in considering why.
There is a difference in risk between day and night approaches with visual separation; the higher risk judged tolerable at the time of implementation. However, relative risk changes over time.
Not so much the physical aspects, but with time itself; the longer exposure in continuing use of a procedure with risk can reduce comparable levels of safety. Also, the risk relative to the overall (decreasing) risk in industry (increased safety), then constant low risks appear higher.
Thus the safety concepts of continuous review, assessment, need to change; not accepting the status quo, being cautious of complacency.
In this incident there is a clash of views; individual, organisation, regulation. Therefore the need to understand these differences with well reasoned argument and justification (before the fact), and from that understanding, learn and be willing to change.
On one hand in this incident there are established operations, on the other an operator who chose to change; adapt existing procedures to maintain an acceptable level of safety (in their view), with changing time.
This could be one lesson to heed; high levels of operational safety are not constant with time. Review, debate, change as necessary to avoid complacency.
