Hi,
You do a 2-day skills assesment at OAT!
There is a sim check it really isn’t to test your flying ability since a integrated course is designed for students with little or no flying experience!
The sim is just to make sure you can listen to instructions and have a learning curve, also makes sure you have the hand eye co-ordination!
If you want more info on the selection run a search on PPRUNE, or visit the OAT website itself!
