Sorry all,
I'm with Bearcat on this one.
We have a huge training committment at LHR, admittedly our trainees get 100 hours in the sim first, but we never slow the traffic down in the real world for a trainee. We have 2/3 trainees per watch (although they are dropping like flies) so with spin shifts included, that means that at any time between 0630 - 2300 of the 5 operational LHR tower frequencies 3 or 4 could be operated by trainees.
If we slowed the traffic down so they could learn at an appropriate pace, the shambles that it is LL would fall to pieces in minutes.
If the traffic is above the trainees capability the OJTI should step in.
If they 'aren't' doinf this at Malaga then that's poor, plus it does the trainee no benefit to have a traffic scenario that falls apart around them, having them constantly playing catch up!
