You will need to telephone the members of the Hampshire Police Authority. Their telephone numbers are mostly published as per Mike's link above. One can only assume that as the numbers are published they will not mind taking your call. The meeting is on Tuesday.
You can view the report that the Chief Constable proposes to give as part of the meeting agenda here:

It is now becoming increasingly clear that the Chief Constable is being very badly advised - how the Hampshire Constabulary think they can revise the terms of the Chicago Convention is beyond me. My suggestion to him would be, 'When in a hole, stop digging'. Hampshire Police would be well advised to get back to their core business of catching criminals and leave running airfields to those who are actually competent to do so.
