The NPPLSC has yet to agree what requirements should be in place for NPPL-holding instructors. However, the figure of 150 hours is certainly incorrect, there will still be a requirment for commercial level knowledge (the exact level to be agreed), a pre-entry flight and theoretical knowledge check before a formal FI(R) course and FI(R) Skill Test.
The only remunerated instructing which might be proposed would be strictly within a Club environment; the aim is to make things simpler for those who genuinely wish to instruct, not to facilitate a method for airline-wannabe hours builders.
NPPL-holding FIs are still a long way off - the licence itself will not appear before 'early 2002' and the demand for it will greatly influence the NPPLSC in deciding whether there should be further progress towards NPPL-holding FIs remunerated or otherwise.
