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! Lets break down the six types of airspeed!

Winds aloft, true course, heading and groundspeed. Which statement about longitude and latitude is true? How far will an aircraft travel in 2 minutes with a groundspeed of 120 knots? When converting from true course to magnetic heading, a pilot should add westerly variation and subtract left wind correction angle.

The electronic E6B is equally useful when in the airplane, to help determine actual winds aloft, true airspeed, fuel burn, and descent planning. Calculate the planned groundspeed if the winds aloft are forecast to be from 250 at 15 knots flying a true course of 130 with a true airspeed of 112 knots.

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. Be careful interpreting the scales. The fuel consumption for your flight.

Particular attention to true airspeed vs. turn radius. The rule of thumb is VSI = ½ groundspeed times 10. For example, some aircraft limit flaps and gear in icing until on approach or forbid the use of speed brakes or require a minimum thrust setting. This will work well up to about 10 kts of headwind.

So, there you are, flying at 6,000 feet with a nice tailwind, riding the wave of speed looking at the groundspeed hit the marks you have not seen in a while. You look at the multifunction display and notice the groundspeed is slowing down to your true airspeed as if the wind has suddenly traded in for calm.
