I have it on very good authority (a source who is working at CHA) that these aircraft have been approved by the military to operate under CFAOS to provide 3rd party training for exactly the same sort of work which Cobham previously taught at Shawbury & Valley.
Rumour on the block is that they have already picked up some good contracts, infact I have seen some of the CHA bods sharing the press releases via Linkedin.
