Supafly,
I don't think the EJ TRSS scheme is really an alternative to the ATP scheme for low hours pilots with just the basic license. Although the published miniumum time for TRSS is 500hrs, the TRSS is aimed at guys and gals with turbo-prop experience - the lowest experience level I have heard of getting onto that scheme is multi-piston IFR air taxi type experience - but I'll happily stand corrected if anyone knows of 500hr single-piston fATPLs being accepted (without some personal connection anyway).
