I'm excluded on the basis of stupid tests of limited relevance aimed squarely at those with no experience. If these tests are so flawless then why the need for a sim assessment? But like the Murphy's..
It's their train set after all.
The aptitude tests and the sim ride are looking at different things. Yes they don't want you to fly the sim badly but the main focus in the sim is on capacity and CRM.
BA is peculiar, a law unto itself, but, as has been mentioned, it is their train set and you have to play by their rules. No system is ideal but the selection does tend to provide BA with a fairly uniform and reliable product with very few oddballs. it may not be everyone's cup of tea but it does seem to be what BA wants.
