The RVSM EFFECT on Performance Capabilities
The Cessna Conquest II Model 441 is a candidate for RVSM compliance because of its exceptional performance capability and its type-certificated maximum operating altitude of 35,000 Ft. Of special note, the AFM Supplement for -10 equipped aircraft specifies an All-Engine Service Ceiling of "Above 35,000 Feet".
NUMBERS TELL THE STORY
A review of the 441's AFM brings into perspective the operational and performance impact of non-compliance with RVSM requirements.

The decrease of total fuel burn associated with Maximum Recommended Cruise Power must be viewed as a substantial cost benefit, as this directly equates to additional fuel costs when operating at lower, less efficient altitudes. And the increases associated with Endurance and Range allow considerable mission flexibility.
