![]() ![]() Jeffrey has more than 2,000 hours of flight time in modern chariots, including Cirrus Perspective SR22 Turbos, Bonanzas, Cessnas and Piper Aircraft. And, he has authored more than 350 weblogs during the past 7-years on general aviation trends, high performance airplanes and cost of ownership. He has written articles, such as, "The Value of Shared Aircraft Ownership," which was published in Cirrus Pilot Magazine, April 2020 and "A Clear Solution for Ice Protection," published in the Special Safety Issue, Cirrus Pilot Magazine, April 2018. His company provides cloud-based Interactive Aviator Software on iPhone and iPad to help pilots find, connect and share their passion for flying with fellow aviators. Brewer is the CEO and Founder of Connecting Aviators®. Getting an airplane into best cruise performance can be affected by several variables: weight & balance, density altitude, and pilot process variation.Ĭopyright 2016 wikiWings, LLC, All rights reserved.If you’re on an IFR flight plan obtain ATC approval for deviations above your assigned altitude.Your highest cylinder head temperature may be lower. With the nose slightly lowered and in a 400 foot per minute descent the cylinder head temperatures cool and the plane will be correctly positioned for cruise when leveling off. Try the “process check” to enter cruise from just above the selected altitude. If you’re entering cruise from below and remaining in a slightly nose up attitude that can contribute to a higher cylinder head temperature. Cirrus Aircraft measure each cylinder head and exhaust gas temperature, turbo inlet temperature, fuel flow, etc. Today’s GA aircraft have amazing engine monitors. If you’ve sometimes reduced power too early you may find a better cruise speed. Compare your true airspeed results. This procedure for getting “on the step” reduces pilot process variation associated with relying only on engine power to accelerate into best cruise speed from below. Use the operating manual procedure to set power and mixture for cruise (See last week’s article for instructions). In the Cirrus Turbo it’s called the “Big Pull.” You don’t have to stay at full power for several minutes. Pull the throttle back as the plane is descending. This will set the plane in a slightly nose down position and use aircraft momentum to accelerate into best true airspeed (TAS). Then touch the autopilot Vertical Speed (VS) and dial in a 400 foot per minute descent. Upon reaching 17,600 feet, reset the altitude select to 17,500 feet. In a full power climb from below, select an altitude 100 feet above the target cruise level, in this example 17,600 feet. Here’s a process check using the GFC-700 autopilot in a Cirrus Perspective SR22TN Turbo. No delay – you don’t wait on engine power.With a 315hp (235kW) turbocharged Continental TSIO-550 engine, SR22Ts achieve up to 213kt cruise speed and 1,021nm (1,891km) of range, according to Cirrus’ website.Flying the step, Cirrus SR22TN, FL17.5, TAS 189 kts., GS 194 kts., 76% power., 2510 RPM, 29.7 MP, 15.7 GPH, credit wikiWingsĭo you always reach best true airspeed in cruise? You should know this step to use aircraft momentum from slightly above a selected altitude to accelerate into best cruise speed. “The biggest increase in speed will be seen in the SR22T at. ![]() “In practice, our owners will find that the actual will exceed book value,” Cirrus says. The figures remain unchanged from the previous SR models, it says. Though the company says the 2022 models are faster, Cirrus did not update speed figures in the types’ pilot operating manuals or in marketing materials. ![]() The 2022 updates apply to the three Cirrus SR models: the SR20, SR22 and SR22T, Cirrus says. “These aerodynamic refinements contribute to both reduced fuel consumption and faster flight segments.”Ĭirrus launched the “G6” – or sixth-generation – series of the five-seat SR-series in 2017. “The new model’s ice-panel transition seams are smoothed and wheel-pant tolerances tightened to reduce drag,” it adds.
