3. Minimum heights
(5) Nothing in this Rule shall prohibit an aircraft from:
(a) (i) taking-off, landing or practising approaches to landing,
in accordance with normal aviation practice at an aerodrome or heliport within the State, or at an aerodrome or heliport in any other state, and without causing undue hazard to persons or property.
The interpretation of "undue hazard" or unnecessary risk would be the issue
Personally I think the whole paragragh may be an issue! Starting with 'Normal Aviation Practice'
