I was 'The Greaser's' partner on his sim detail and we have both got offers. The briefing that we got on the day really helped and set the scene for what I believe BA were trying to get from the detail. Whilst knowing SIDs, STARS, airfields, approaches and injects that have been used may be of some comfort, as our assessor said:
'we know that there is info on the internet about the sim, please approach the detail without any preconceptions about what you may think might happen'
I think that BA are looking for trainablity and how you work together over pure flying accuracy. It would be churlish to invite 'dislocation of expectation' when the scenario veers away from the PPRUNE model.
The detail that I flew with 'The Greaser' seemed to go relatively smoothly, but talking to friends who been for the sim, they have had a varied experience, mainly due to the interactions with their partner.
