It will be interesting to see whether the very recent amendment of the Aircrew Regulation will have a significant impact upon 'trial flights'.....:
(13) Commission Regulation (EU) 965/2012 allows certain flights such as cost-sharing flights and introductory flights to be performed in accordance with the rules applicable to non-commercial operations of non-complex aircraft. There is, therefore, a need to ensure that the privileges of pilots established in Regulation (EU) 1178/2011 are consistent with this approach.
(14) Therefore, it should be allowed to have flights of those categories identified in Regulation (EU) 965/2012 to be piloted by PPL, SPL, BPL or LAPL holders.
(15) The measures provided for in this Regulation are in accordance with the Opinion of the European Aviation Safety Agency Committee established by Article 65 of Regulation (EC) No 216/2008
(16) Regulation (EU) No 1178/2011 should therefore be amended accordingly.
