Theoretically, it was possible to use the combination of the indicated airspeed
and total temperature to serve the same purpose.
That's because the E5 can use GPS groundspeed instead of indicated airspeed
as part of its overall AHRS solution.
"If your POH/AFM does not have minimum icing airspeeds, add 15 to 20 knots indicated airspeed
to your normal operating airspeed.
You'll have a diminishing tailwind, so you'll have to keep reducing your rate of descent for a steady indicated airspeed
When flying at mid-range airspeeds (50-100 knots indicated airspeed
, KIAS) often used for instrument approaches, the MH-60R BARALT indicates 40-to-60 feet (nominally 50 feet) lower than it should.
With an approach speed of 186 knots indicated airspeed
, significantly higher than normal approach and landing speeds, Capt Wright was concerned with a landing distance that approached 90 percent of the runway available.
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 other thing I'd try to change by going back in time is how we have adopted the concept of stall speed, as if there is one and only one indicated airspeed
at which a given airplane will stall.
One feature we've grown to appreciate with Garmin's GlOOO-integrated GFC700 is indicated airspeed
hold, and the 3100 has it, too.
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
(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.
