true airspeed

[′trü ′er‚spēd]
(aerospace engineering)
The actual speed of an aircraft relative to the air through which it flies, that is, the calibrated airspeed corrected for temperature, density, or compressibility.

The AV-20-S's gyro function is one of many features in the instrument, including multiple pages for angle-of-attack indication, G-meter, OAT, true airspeed, bus voltage, density altitude and clock and timer functions.
(We'll assume the engine has been leaned for best power rather than left at full rich, another characteristic gotcha.) Recall that in thinner air, greater airspeed is needed to produce comparable lift--but the true airspeed corresponding to any indicated airspeed is also higher.
This upgrade delivers a 22% increase in available horsepower, which translates into maximum cruise speeds of more than 302 Knots True Airspeed (KTAS), increased single engine service ceiling, and shorter times to destination.
Sure, I've filed and flown much lower--usually westbound when the headwinds are half my true airspeed up higher--but if I'm already IFR, I can request any altitude that makes sense for me, for the airplane, the weather, and for the terrain.
The ADS provides direct measurements of the aircraft true airspeed; typically connected with the ADS are the vanes for measuring the important aerodynamic angles known as angle of attack and angle of sideslip.
Flight distance was determined by integrating true airspeed between takeoff and landing
The jet is expected to fly 420 knots true airspeed at maximum cruise at FL300, with a maximum cruise altitude of FL430, according to a spec sheet provided by the company.
Cruising speeds would be between 0.75 and 0.82 Mach, and 350 knots indicated airspeed, which equates to a true airspeed of 550 mph at 25,000 ft.
Later, as we watched the pass on the PLAT recording, we saw the true airspeed go from 150 to 170 knots as the ailerons visibly faired.
As the longest-range business jet in CessnaOs product line, the Citation Longitude is designed to offer an estimated full fuel payload of 1,950 pounds (884.5 kilograms), a maximum cruise speed of 490 knots true airspeed (907.4 kilometers per hour) and a maximum range of 4,000 nautical miles (7408 kilometers).
The simulator test revealed that altitude decreases with [P.sub.S]; hence the [P.sub.S] contours on the altitude versus true airspeed and Mach number plots were turned upside down for both aircrafts.
Indeed, in the altitude range where birds are commonly a factor, up to 10,000ft, speeds are often restricted by regulation to 250 knots indicated airspeed, which would mean up to 300 knots true airspeed, depending on the ambient temperature.
