Flight Examiner Handbook (Helicopters) 2003, section 2.7 says " Examiners are reminded that with the exception of training and tests for the Instrument Rating all other instruction and tests/checks are to be conducted to and from a licensed airfield/site in accordance with the ANO Artcile 101".
Whilst the ANO does not specifically cover the case for an LPC, the above wording does indicate that as far as the CAA are concerned all tests must be conducted from a licensed location.
Any other takes on this wording ?
