I think TV3 bought up quite a valid point re the security at aerodromes, Ardmore in particular. Because there is no scheduled commercial activity security is somewhat neglected compared to the control there is at the designated security aerdromes.
Ardmore however is NZ's busiest aerodrome and there are a lot of aircraft that can be very easily accessed with no trouble at all as the TV3 item showed.
The Australian approach with the ASIC cards does have some merit but graft that onto an Ardmore type aerodrome in NZ and the costs would be prohibitive to already tight operations.
It has been mentioned in the media that in general the threat is low because people who do gain access to an aircraft will either not be able to start or even fly the thing or they will be deterred by the consequence of their potential actions. This may not always be the case have we have seen.
It is not possible to account for every imaginable scenario but is a new approach to security at aerodromes in respect of light aircraft required?
