## What is Radar Performance?

Radar Performance calculates the geometry of aircraft weather radar beams with respect to the earth, the freezing level, and the band of altitudes that provide the maximum weather radar returns (the "bright band"). It also shows the areas on the radar display where the beam is too high or low to effectively detect active weather and areas where you may see ground returns.

Radar Performance also includes an Overfly mode for confirming that the tops of lower-level convective weather remain safely below your aircraft. You choose a safe clearance altitude and a tactical range, and the app calculates the radar tilt at which the bottom of the beam just reaches that altitude at that range. With this tilt set, any weather returns indicate that the tops have penetrated your safety margin, so going around the weather is advised. Overfly mode is available at aircraft altitudes of 15,000 ft and above, and is inspired by Tom McGrath's "Snowplow" technique.

Radar Performance supports a variety of weather radar models as well as a "generic" model. It is not specific to any aircraft type.

This app dev has continually added support and apps. I started with the bonanza app. Radar app is helpful with new bird. Thanks.

## Frequently asked questions about Radar Performance

### 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?

The provided description does not specify offline functionality. However, as a calculation-based utility, it is likely to function without an active internet connection once installed.
