Privided always that:
(a) the Insured and/or the pilot conducting the flight has obtained the permission of the owner or the tenants of the land;
(b) the Insured and/or the pilot condusting the flight has ascertained the suitability of the landing ground and has enquired from the landlord/tenant or from their authorised representative the condition of the landing ground at the expected time of arrival;
(c) the pilot conducting the flight has surveyed the landing ground by flypast or overflight immediately prior to landing.
c is just daft. Can you imagine turning up at many fields requiring PPR and insisting on a flypast or overflight? What exactly do you hope to achieve by an overflight? You will do well to establish if the runway is suitable. It is one thing to carefully assess a farm strip, quite another to be making a similiar assessment of some well know PPR "airports".
