TT - what do those 25 hours consist of? If they're SEP instruction they should count.
The issue of NPPL(SEP) holders being permittted to hold some form of FI rating is a thorny one. Some are in favour, others vehemently against. My personal view is that any FI(NPPL(SEP)) should have at least the same level of training and theoretical knowledge as did the old BCPL/FI and the same rights of remuneration. Perhaps there could be a 'Basic FI' course which would encompass all such training; however, any 'Basic FI' should have rather more qualifying experience than the modular CPL holder. That would be in order to atttract only those who really have an interest in flight instruction rather than those merely looking for a way of 'hours building'. But anyone taught by a non JAR-FCL FI may have difficulty upgrading to their own JAR-FCL PPL under current rules.
The NPPLSC is required by its own earlier decision to start discussing the concept of NPPL holders instructing for remuneration at the next committee meeting.
