Radar Performance vs Phenom Landings

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.

Phenom Landings turns the QRH operational distance landing tables for the Embraer Phenom 100 and Phenom 300 into a fast, transparent calculator you can run right at the runway — with the conditions that actually matter and a built-in check that refuses to hand you an unsafe number. PERFORMANCE • Phenom 100 (E50P) and Phenom 300 (E55P), with both FAA and EASA data • Adjusts for weight, flaps, head/tailwind, crosswind, temperature, field elevation, runway slope, runway condition (RWYCC 1–6), ice accretion, overweight, and speed above Vref • Full penalty breakdown — see exactly how each factor changes the distance • Hard operational limits (slope beyond ±2%, tailwind beyond 10 kt) block the result instead of showing a dangerous one AIRPORTS & RUNWAYS BUILT IN • Search tens of thousands of airports worldwide • Per-runway length, surface, slope, and Landing Distance Available (LDA) • Automatic best-runway suggestion based on the wind • US runway slopes from FAA surveyed elevations and published Chart Supplements — with a clear "verify" caution whenever the data is uncertain WEATHER IN ONE TAP • Live METAR observations and TAF forecasts • Pick a forecast time to plan ahead • No signal? Scan a METAR or TAF from your camera or a photo of the METAR on your MFD. The app reads the wind and temperature for you FITS HOW YOU FLY • Ask Siri: "Calculate landing distance at KSFO in Phenom Landings" • Share a weather screenshot straight into the app • Home-screen widget and iCloud sync for your favorite airports • Quick, glove-friendly input designed for the flight deck IMPORTANT Phenom Landings is an advisory planning aid, not an official performance source. Always verify against the approved Airplane Flight Manual (AFM), Pilot's Operating Handbook (POH), and Quick Reference Handbook (QRH). Data and weather may be incomplete or contain errors.
