Lets set the record straight. GLA was a DEC, not that the fact is necessarily relevant. The facts surrounding this incident are unknown by most and therefore most professional pilots are refraining from passing judgement.
Munich was an outright component failure, I'm assuming you're referring to the broken axle.
The DEC with the barrier incident, that was just the tip of the iceberg. Right call in my opinion but it wasn't his hired status (DEC) that controlled his style of operation.
Most of the DEC's here are competent enough. Question is, are they necessarily anymore competent than upgrading an FO? In most cases the answer is an emphatic, no. Thousands of hours implies ability, it doesn't prove it.
Regardless of anyones opinion, DEC's have been hired in the past and the policy will continue to remain in place.
Back to the thread. Yes there should be an interview for command upgrade. I also believe that the whole DEC/Upgrade process should be reviewed/adjusted to ensure a common product after FLC. Another airlines command process is not necessarily an appropriate benchmark for Emirates and the interview is inconsequential for anyone that is up to it.
