If you’re aiming to get comfortable with managing both airspeed and altitude in flight, you’ll need to understand the difference between indicated airspeed (IAS) and true airspeed (TAS).

This section is also needed when youre calculating your true airspeed, which you need to know to plan your flight. Step-by-Step: How to Use the E6B for Time and Speed Calculations Calculating Time en Route Lets say were flying at a constant airspeed of 100 knots. That means our groundspeed was 90 knots.

On one trip home, we had a 50-knot headwind, really annoying at a true airspeed of only 125. One flight, given instructions to cross whichever end of the Phoenix Sky Harbor International Airport (KPHX), things just didn’t seem right in the cockpit. Next morning, we took off before the fires really got going again.

A spring switch in the cockpit controlled the turbocharger wastegate, to select whether the turbocharger was engaged or bypassed (or midrange). With the turbocharger engaged, the engine would produce 2,300 rpm; however, with the turbocharger bypassed, the engine would only produce about 2,050 rpm.
