Recently I got asked by Air Navigation Pro to answer a couple of questions for their blog. I use their application for navigation on my Ipad during my fligths…

I got featured on their blog, and you can read the full story here: http://blog.airnavigation.aero/2017/12/air-navigation-pro-pilot-story_18.html

Safe flying! 🙂

About to touch and go at La Palma airport (GCLA)

In this short clip I’ll explain you how to calculate the true airspeed. Knowing the true airspeed and the ground speed, we can determinate whether we have headwind, or tailwind.

It’s very simple:

FL 75 (7.500 ft)
IAS = 90 kts
TAS = 100 kts (TAS inceases with increasing altitude)
GS = 109 kts

if

GS > TAS => have tailwind
GS < TAS => headwind

This means in our case, we have 9 kts TW (tailwind).

Fly safe! 😀
