Thanks Wingswinger, exactly what I was about to say. Hansoff, the minimum standard required in any sim check is laid down by the regulatory authority. A company is perfectly entitled to set a higher standard than this (never lower). This may be set out in their Ops manual, which is approved by the regulatory authority and once so approved must be adhered to. So if its in your approved manuals then that is what the bench mark is. Hope that is of some help
