Flying in a jet without RVSM can potentially decrease the patient’s safety and comfort with increased fuel stops, longer flying times, and more turbulent weather, affecting the quality of care the patient may experience.

Why is it important? Some air ambulance companies that have older aircraft (particularly Learjet 24’s and 25’s) did not convert their jets to RVSM due to the time out of service and costs involved. These aircraft may have to fly at lower altitudes in order to stay out of RVSM airspace.
