About
This application calculates the geometry of aircraft weather radar beams relative to Earth, the freezing level, and the "bright band" for optimal weather detection. It identifies areas on the radar display where the beam is too high or low for effective weather detection and highlights potential ground returns.

FAQ
What is Radar Performance used for?
Radar Performance calculates the geometry of aircraft weather radar beams in relation to the Earth, the freezing level, and the 'bright band' to optimize weather detection. It helps users understand where the radar beam is most effective and where it might miss weather or detect ground returns.
Does Radar Performance have ads?
Yes, Radar Performance contains advertisements. As it is a free application, ads are displayed to support its continued development and availability.
What devices is Radar Performance compatible with?
Radar Performance is available for iPhone, iPad, and iPod devices. It is designed to run on Apple's mobile operating system.
How accurate is Radar Performance?
The app's accuracy is based on geometric calculations of radar beam behavior. While the app itself is a tool for understanding these geometries, the effectiveness of radar detection ultimately depends on the aircraft's specific radar system and atmospheric conditions.
Is Radar Performance suitable for beginners?
Radar Performance is designed for users familiar with aviation and weather radar concepts. While it provides calculations, understanding the meteorological and geometrical principles behind them is beneficial for optimal use.
How often is Radar Performance updated?
The latest version available is 4.4.14, last updated on March 3, 2026. This indicates a recent update, suggesting ongoing maintenance and potential improvements.
What is the age rating for Radar Performance?
Radar Performance has an age rating of 4+. This means it is considered suitable for users of all ages, with no mature content.
Can Radar Performance be used offline?
