CNS 33 HENDO Mess

[Lookleft]

Internal comms were sent re this incident to ensure no one else falls into the same trap (of failing to select both the STAR and approach transitions).

This seems to be where we started. Its not a trap if it is a requirement to read back the transition as part of the clearance and then not insert it into the FMC then not cross checking it. An error would be for one pilot to omit the selection. In TEM parlance an error led to a UAS. Not a trap but a failure of procedures and proper monitoring. I will let you work out where a UAS leads if you even understand the term.

​​​​​​​It’s great to see that you hold your airmanship in such high regard.

Not really, just an example of taking the threat seriously. It doesn't take superior airmanship but it does take a modicum of attention to what will kill you if you don't pay attention to your environment.

I'm pretty sure the Hendo Transition is not provided as part or the clearance, so nor is it read back by the crew. Working out that it needs to be selected is up to the crew. It is not always obvious, so yes, in a critical terrain environment such as this, it's a trap.

Yes this is the issue. The transition you read back is the STAR transition. You just have to know to put the approach transition and the STAR transition in the FMC and I don't believe it is uniform across the country.
