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.
