I flew with a new recruit the other day. He was PNF (PM if you prefer).
As we trundled down the parallel taxiway, about half way through the Before Take-Off Check, the Cabin Call went off. Just the regular 'Cabin Ready' info from the Purser - always comes at the most inopportune time.
Having finished that he returned to the Checklist. From the top.
Hang on I said, we know where we were, so lets continue from there - we're getting close to the hold and we're number one.
But Captain he replied, thats not what my instructor taught me in Line Training.
Ah well I thought - it'll be quicker to just do that, rather than debate the issue now.
Afterwward we talked about it, and yes indeed, some genius is telling the kiddies to do this.
To my knowledge the industry standard practice is to HOLD the checklist on interruption, marking the line with your thumb preferably, then continuing from that point afterward.
If you lose your place, then yes, start again. But show a bit of professionalism - some airmanship - and don't lose your position in the checklist. Stop day-dreaming?
Why do we always have to make the SIMPLEST things the most DIFFICULT?
