indicated airspeed

[′in·də‚kād·əd ′er‚spēd]
(aerospace engineering)
The airspeed as shown by a differential-pressure airspeed indicator, uncorrected for instrument and installation errors; a simple computation for altitude and temperature converts indicated airspeed to true airspeed. Abbreviated IAS.

Theoretically, it was possible to use the combination of the indicated airspeed and total temperature to serve the same purpose.
During the course of its three-hour, 44-minute flight northwest of Toronto, it reached a maximum altitude of 45,000 feet (13,716 m), and a maximum indicated airspeed of 340 knots (391 mph; 630 km/h).
Its indicated airspeed was between 87 and 90 knots, and vertical speed increased from a 240-fpm descent to 1056 fpm.
With a stabilized vertical speed, indicated airspeed and power setting, if one of those parameters changes quickly or significantly and you did nothing to change it, then it was changed by a force outside the aircraft.
I assumed that he had heard me, and I matched up our pitch-feel airspeed to our indicated airspeed manually, in accordance with the Flight Control Malfunction emergency procedure.
They also calculated that an explosive brake situation would develop if braking was initiated above 140 Knots Indicated Airspeed (KIAS).
The leader was behind on his timeline to make the assigned time on target and was traveling at 520 knots indicated airspeed vice the prebriefed 300.
The math works out that a 100-knot indicated airspeed at sea level produces 120 knots true at 10,000 feet msl.
Indicated airspeed, true airspeed, and rate of descent were all pumped into a spreadsheet.
So instead of GPS groundspeed and pressure altitude, the device--running through a tablet app--will display indicated airspeed and pressure altitude.
Maintaining the indicated airspeed required looking at the instrument panel, while also looking out to line up on the ship's centerline.
