The Midlands Air Ambulance spent £6.026 million from April 2010 to April 2011. It received £5.32 million from charities, £640,000 from trading and other smaller sums.
The CALSTAR air ambulance company based at McClellan Park in North Highlands has added a large, high-flying patient transport plane to its fleet.
The cost of fuel means Midlands Air Ambulance is facing "a challenging time" as it marks 21 years since its first rescue.
