A U.K. HEMS operator who rely on freelance cover are known to demand roughly 3 days in return for an OPC, plus any line training days are unpaid. Part of the race to the bottom. Another who are supposedly multi crew and extend hours during summer expect freelancers to pay up to £2700 per hour in the charities own MD902 for a limited VFR p2 only type rating for an IFR operation. Seems though the caa are ok with that.
