Airspeed guides everything from takeoff to landing and every phase in between. But did you know there are several types of airspeed, each serving a unique purpose? Like Indicated Airspeed (IAS) , Calibrated Airspeed (CAS) , True Airspeed (TAS) , and more! What Are The Different Types of Airspeed?

Airspeed and altitude differences Consider speed first. The panel in your airplane shows indicated airspeed (IAS, derived from the pitot tube on the wing), while the iPad shows groundspeed (derived from the GPS in your ADS-B receiver or iPad). Here’s a somewhat geeky dive into the details.

Learn how to use the wind side to find groundspeed and wind correction angles. Your groundspeed (which will differ from your airspeed as the wind pushes you around). The rear has the wind side for calculating wind correction angles and groundspeed. That means our groundspeed was 90 knots. Thats not all.

What specific indicated airspeed will be flown/adhered to during the circling maneuver? The rule of thumb is VSI = ½ groundspeed times 10. Is the airport have an operable FAA tower or is it an uncontrolled field environment? A well briefed “transfer of aircraft controls” is paramount. What speed on final approach?

Flying to Oklahoma from New Jersey in my G36 Bonanza, I once encountered a mountain wave where the indicated airspeed changed from 92 knots to 164 knots without a single bump. On the East Coast, the Appalachians, and in the West, the Rockies, pose an interesting turbulence threat. As we turned back, the wind shear hit.
