Sure worth to buy

I use it in the 737... For to main reasons... Time calc... Made simple... And the other is to calculate the vertical path. The airplane does a good job... But the calculations my instructor teached me make the airplane descent in a more constant path... To do mental calculations and fly the plane may be stressfull sometimes... Here is where the app makes the difference... Using the vertical profile calculator... Using the distance , altitude i have to be in the next waypoint, and glide angle, i get a precise altitude to be passing, and know if im to high or to low. Sure recomended!
