Because each funding transfer incurs a cost which the CAA has to pay from the 8.33 pot, the plan is to minimise that by releasing the first tranche in one go in about (I gather) 4 weeks' time.
That will then mean more funds are available for the next tranche, rather than having had to be spent in admin. The CAA has made it quite clear that the maximum possible level of funding shall go to the end users and NOT get tied up in admin fees, so their plan should now ensure that the 8.33 pot will benefit as many aircraft equipage applications as possible.
