A turbocharged Cirrus can cruise from 18,000 to 25,000 feet. These altitude choices are not available to normally aspirated piston engines.
Reason 10 – Reach Higher Cruise Altitudes (18K – 25K)
At these flight levels, a turbocharged Cirrus, with the right tailwind, can exceed 300 knots ground speed.
The certification altitude up to 25,000 feet MSL is lower than the turbocharger’s critical altitude. Critical altitude is the height at which a turbocharger can no longer support sea level pressure, which is not an issue for the Cirrus SR22TN.
