I've asked the Authority again along the following lines:
You kindly put the question of training credit towards a PPL course for a student who hasn't completed a LAPL course to EASA in Dec 2016. Despite the 2013 TAG/SSCC/FCL agreement, EASA's response to you stressed that the only credit available towards a PPL was for a pilot who holds a LAPL - no credit is available for a pilot who hasn't completed the course.
Has this policy now changed? The reason I ask is that some seem to have been told that such credit IS now available.
