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.
