RVSM is an abbreviation for Reduced Vertical Separation Minimum. This modification to each jet in service has been required by the FAA since January 2005, if a pilot wants to fly above 29,000 feet. Many Lear jet owners have decided not to make this modification. Without this modification, jets must fly at lower altitudes.

Why is it important? Flying at lower altitudes requires additional fuel stops, longer transit times and flying in more turbulent weather, affecting the patient’s safety and comfort.
