A Douglas North MHK says he wants reassurance critically ill people can be taken to hospital if the Island's air ambulance is out of commission.
In the House of Keys tomorrow David Ashford will quiz the Health and Social Care Minister about the department's contingency plans.
Mr Ashford says his question comes after technical problems temporarily grounded the aircraft which provides the service.
He says having a backup is crucial:
Two more schemes backed by government fund
Island to get Bikesafe scheme for first time
Jurby Junk's Stella dies aged 90
No plans to publish UK's assisted dying letters
Burst water main disrupts Onchan supply
Government advice following spike in data breaches
Plans for four-foot flood walls at Ramsey harbour
Garage blaze in the early hours of this morning
