In simple terms....what is the difference between Casevac and HEMS in the UK. In the USA we use a singular definition.....HEMS is Casevac is HEMS.
We provide 24 hour service. We use NVG's. We land at ad hoc sites at night.
If the operation is conducted in VFR/VMC conditions....why the phobia about landing at night or even flying at night for the purpose of transporting critically ill or injured persons?
