"ex-QFI AEF pilots will provide EFT..."
That's most interesting and, to some extent, what I feared. Any such 'instruction' carried out by pilots who are neither current QFIs nor civil FIs will not be viewed as valid flight instruction for either a JAR-FCL PPL or a UK NPPL. It will be viewed as 'passenger flying' only.
I raised this point with the CAA recently; current accreditation will most certainly be reviewed should any change occur in current UAS training standards.
