## What is MEA PBN ALT?

I created this app to help visualize the Altitude corrections due to cold weather. The calculations are made using the ICAO formula from doc 8168. I have made the Intermediate and Final Approach and the Go-Around. So you have a complete approach displayed if needed. Works in feet, meters and in Celsius or Fahrenheit. Many thanks, I hope you enjoy it, and any feedback is always welcome. This new version includes wind error corrections to Altitude. Quick Reminder: USE ONLY FOR PRACTICE PURPOSES.

## Key features

- Cold weather altitude corrections
