Local MP Simon Hart is seeking reassurances that Carmarthenshire won't lack policing cover when the Dyfed-Powys helicopter ceases to fly from Pembrey next year.
Mr Hart has now written to the Chairman of the National Police Air Service (NPAS), Mark Burns-Williamson asking for reassurances about the future service.
Mr Hart said: "I am frustrated that once again the future of our helicopter service is subject to uncertainty.
"There is a possibility that on the plus side helicopter cover may extend from 12 hours a day which we now have to 24 hours.
"But this has to be weighed up against the fact that it will take at least ten minutes longer for it to reach our part of the world."
Mr Hart has asked NPAS to confirm:
What new cover this proposal will provide in Dyfed-Powys?
What measures are in place should the aircraft be grounded for maintenance purposes?
Will the 20 minute response commitment time remain in place and if not what will the new proposals entail?
What are the financial consequences of these changes be?
What risk assessment has been made of the impact of these changes on the area?
"I think that minds will only be put at rest when we have had some answers to these queries," he added.
