Calculating True Airspeed Follow steps 1-3 from the section above. Find your Calibrated Airspeed on the middle scale on the movable disk. Thats your true airspeed. Calibrated airspeed is not the same as indicated airspeed. The weather station reports wind from 030 degrees at 20 knots.

Aircraft contain all kinds of wonderous indicators and instruments to measure velocity, altitude, weather conditions, etc. However, the single most important aircraft instrument is probably the airspeed indicator. A plane’s specific stall speed depends on the plane’s size, dimensions, and even weather conditions.

Isn’t it interesting to know that based partly on measurements from weather balloons, you can predict the way the winds aloft are going to cause your plane to drift as you fly from point to point, and that you can correct for that as you fly? Winds on the surface, and winds at altitude: both concepts are covered in the nav-log lesson.
