So Morno, you are and Octas are asserting anyone who obtained an ATPL prior to Sept 1st 2014 are basically incompetent?
No. Calm down man and take a deep breath.
Anyone who got an ATPL previously, did so with unknown & untested multi-crew management skills. Maybe they were good, maybe they weren't. My multi-crew management skills were non-existent, although I did have good stick & rudder skills.
if you hold type rating and a instrument rating what more is a ATPL check going to do?
Hopefully, ask you demonstrate CPL/IR skills in a complex aircraft with multiple crew. This will require management & teamwork skills which are neither assessed nor required in the CPL/IR skills tests.
