Don't knock the young skippers at FR 9 out of 10 of them are SAFE as houses.
Irrespective of age that should be 10 out of 10!!
It's the swiss cheese model - yes they have had a good safety record (but with a few lucky escapes).
Experience (or not so much of it) is one of the holes in the model. That doesn't mean that (relatively) inexperienced Commanders are not "safe" - remember that RYR does a lot of sectors and, compared to other operators, said Commander will, pro rata, have done many more take offs and landings. They DO have a very robust SOP and training system.
However I see the convergence of quite a few factors (and this isn't only specific to RYR) such as reduction in handling skills due to increased use of automation, over reliance on training SOPs as opposed to understanding and original thought which is required when things are not "standard", repetitive duty days which stretch the limit combined with days off being used to position to/from base, etc etc.
It is these factors
combined with reducing experience levels (in both left and right hand seats) which I see as a threat to safe operation.
