As of 20th April, no externals have appeared on the course appointments list. This could simply be a case of working through notice periods etc before assigning start dates, but regardless, no externals have actually started yet thus the RPPP trigger has not been reached.
I’m unsure if we’re going to see a couple of 100% external courses on the Horizon or if they’ll be slotting them in amongst the internals over say the next 6 months. Either way, the number of externals interviewed isn’t a factor in the RPPP, only the number who actually start, and it’s not uncommon to lose a few to other Airlines along the way.
