Smokin’ fast, as in The Speed-O-Heat. Getting from point A to point B just got a little faster for folks lucky enough to fly in Cessna’s newest Citation X. On October 31, the FAA and Cessna completed test flights that validated the Citation X’s max speed of Mach 0.935. That’s as close to the speed of sound as you can get without strapping on a military jet.
Passenger airliners typically fly around Mach 0.80 (80% of the speed of sound). At altitude, this is about 470kts. The X will max out at around 550kts to create a huge time savings for a long journey. With a max cruise altitude of 51,000ft, the Citation X will slip smoothly over top of all but the most severe weather – airliners typically cruise around 35,000ft or so.
For years the Citation has endured the affectionate but unflattering nickname: “Cessna Slow-tation”. I think it’s safe to retire that handle and adopt something that sounds faster. A lot faster.
