It's a helicopter thing!
The new text of JAR-FCL 2 Amendment 4, proposed in NPA-FCL25 is as follows:
(a) Restricted period. Until the holder of a FI(H) rating has conducted at least 100 hours flight instruction in
helicopters and, in addition has supervised at least 25 student solo flight air exercises, the privileges of the rating
are restricted. The restriction will be removed from the rating when the above requirements have been met and
on the recommendation of the supervising FI(H).
(b) Restrictions. The privileges are restricted to carrying out under the supervision of a FI(H) approved for
this purpose:
(1) flight instruction for the issue of the PPL(H) – or those parts of integrated courses at PPL(H)
level – and type ratings for single pilot, single-engine helicopters, excluding approval of first solo
flights by day or by night and first solo navigation flights by day or by night; and
(2) night flying instruction, provided a helicopter night qualification is held, the ability to instruct at
night has been demonstrated to a FI(H) authorised to conduct FI(H) training in accordance with
JAR-FCL 2.330(d) and the night currency requirement of JAR-FCL 2.026 is satisfied.
It would appear that the UK have elected to implement the provisions of Amendment 4 prior to its publication, always assuming that the examiner concerned got it right.
