When I discussed the absence of (ops manual specified) night training in Shetland I was told that we didn't do them often and just to keep my fingers crossed that I wasn't called out at night. Later the same manager said "breaking the law is the only way we can get the job done" I and my colleagues disagread. After that I talked the NHS in Shetland to fund the Garmin. Management disaproved strongly, but I noticed that 'management' flew with GPS. I never did get any night training. I believe Tinstaafi got the first and his 'trainer/manager' also had his first experience of night outer isles ops on the same flight.
To get an idea of whats involved in ambulance night ops read 'Islanders Islander' on the Fair isle airstrip website.
