Exploring the Intricacies of the Airspeed Indicator

Pilot's Life Blog

Static vents that measure static pressures are usually on the lower side of the plane, where the air stream isn’t as turbulent. True Airspeed vs Indicated Airspeed VS Equivalent Airspeed Since airspeed indicators use air pressure to measure speed, the indicated airspeed can be less than the actual airspeed at higher altitudes.

Air Facts

To get the extra lift required for the turns, I had to dive to get extra airspeed so that the plane could turn at that same AOA. And some made it as high as 100 feet but were still consistent with the spirit of FASF. That produced a strange traffic pattern with roller coasters at the corners.)

At one point, we entered a region of sufficient turbulence that I disengaged the autopilot to hand-fly. Caught in series of up and down drafts, the autopilot pitched the Warrior aggressively to maintain altitude and the indicated airspeed trended too high in each updraft. Still IFR, but barely.

There were some patches of moderate lift and sink as would be expected on a normal summer soaring day. Without knowing the horizontal wind direction and speed at this point it is impossible to say what his indicated airspeed was. Sometimes you fly through virga and you can even find yourself in lift.
