When additional calls are called for by a company over and above “Boeing standard”, it probably due to a previous event and management is now trying to mitigate future threats.
Unfortunately there are some "managements" that seem to think the more 'advisory' comments made by each pilot, the better is the CRM. So in the end it becomes a competition of subtle point scoring. This can be irritating.
"Mitigating future threats" is another motherhood statement that gets right up the nose of some pilots. Boeing use the term 'Verify' and that implies you don't have to articulate - you simply use your eyes.
I remember observing a Japanese check captain sitting at the back of a 737 simulator quietly observing a series of assessment circuits on candidates that had applied for a job in his airline. None of the pilots being tested knew each other and most came from different countries and different airlines with different procedures. It didn't help that the English language skill of the Japanese assessor was poor.
During one circuit the chap in the left seat as PF wasn't flying very well and his PM in the right seat thought he needed coaching. The PM was an Eastern European who could not resist "advising" the bewildered South American PF from the beginning of the downwind leg of the circuit until the end of the landing roll. Most of the time the PM was talking so fast in accented English that the poor bugger in the left seat hadn't a clue what he was saying yet wasn't game to tell him to shut up in front of the Japanese assessor.
As the simulator operator I had to button my lip although I was sorely tempted to say for goodness sake back-off and let the PF fly the aeroplane. Bit it wasn't my train set and it was up to the Japanese checkie to run the show. After the landing we went for a coffee break. On the side I commented to the check captain that I thought that PM was a bit too voluble and in fact may have distracted the PF who was having enough trouble flying the simulator. To my astonishment, the Japanese assessor whose English was very limited, and clearly didn't have a clue what the PM was gabbling about, smiled broadly and said he thought the PM was showing excellent CRM by the amount of advice he was offering to the PF.
The PM was hired by the Japanese operator and I pitied the pilots he would be flying with. The inevitable happened and three months later the PM was sacked after numerous complaints from the Japanese captains he flew with that they were distracted by his non-stop "advice" on how to fly the 737.
There are times when silence is golden. Unfortunately it seems to be a rare commodity on today's flight decks..
