## What is PD Altitude?

If you struggle to work out PRESSURE and DENSITY altitudes then this simple calculator is for you. Simply slide 'Choppy' up and down to set your height and move the pressure and temperature sliders and the calculator will deliver the answer.

For added accuracy, you can even type the numbers in from your keyboard!

If you want to support the developer there is an In-App purchase that will enable automatic calculation based on your current location. Cool eh?

ARE YOU TRAINING TO BECOME A PILOT?
PD Altitude also has a small training section giving you an easy 5-Step process for calculating your altitudes.
