Obla is giving sound advise. Heed his info as a good bases of starting your upgrade.
Have a read of the latest training bulletin. It refers to candidates turning up for command and not even knowing their 9 memory items on the Boeing. Maybe that's why there is a disparity.
There has been little change in the upgrade interview process since l have been here. It is not new. So why is there a sudden surprise that some don't make it? History says that some just aren't prepared or have a bad day. You at least get a second chance or more. Better to find out at this stage than in training, or worse on the line, where there is "no going-back". But this has been spelled out before.
The other day l did a flight with an FO who was coming up for command. He told me his assentiveness had been questioned in the past. Well, did he try to make up for it on that flight, as his interview was coming up. It was annoying to the point of distraction on all parties involved on a late departure. There were many inputs with many questions and solutions offered. But at the end of the day there was only one answer, and unfortunately for him, after all his involvement, the decision was made by load control. Having tried to tell him he had no control over what was going on, he kept on proving his assertiveness. 10 points for that. 0 points for result.
He will make a good skipper, as soon as the assertive stigma collar is removed.
It's all about preparedness and attitude.
Good luck to you all approaching, as most l fly with will be on my OK list for the family to fly with.
