SkewTLogPro vs Glide2

SkewTLogPro gives you one-touch access to powerful skew-t log-p charts. View charts using your current GPS location, airport ID code or lat/lon. Each skew-t log-p chart provides a visual indication of temperature, dew point, winds aloft, and wind speed at various altitudes, as well as Current Radar, Airmets, Sigmets, and SkewT data charted, filtered by altitude. FEATURES: • NEW! View all Sigmet/Airmet on a map and filter by altitude • NEW! View SkewT data charted on a map with altitude filtering, shows potential warnings of Icing, Wind, and Visibility • Ability to view the lifted parcel line • Support for International Airport ICAO codes • View charts along your route using 'View Route' • Support for GFS for all locations outside the continental United States (Option in Settings) • View many values such as CAPE, LI, LCL, and many other options through settings • Save charts for offline use • View Skew T Log soundings by touching a location on a map • View skew-t log(p) charts using your current GPS location, airport identifier or latitude and longitude. • Scroll forward and backward to view past and forecast charts. • History list allows easy access to previously viewed locations. • Select how many previous and forecast hours are charted • Drag on the graph to view each point value • Double-tap to zoom in for more detail on the soundings. • Great for aviators, glider pilots and weather enthusiasts.

Impossible Turn Calculator Know before you go. The "impossible turn" — returning to the runway after engine failure on departure — is one of aviation's most critical and least-practiced decisions. This app helps you calculate whether you can make it back. Enter your numbers, get your answer. Select your aircraft or add a custom one with your own glide ratio, best glide speed, and MTOW Set your departure altitude, bank angle, reaction time, wind, and density altitude conditions See whether the turn is survivable before you ever leave the ground Features: Built-in aircraft profiles with real-world performance data Custom aircraft support — add any type with your own specs Density altitude calculations with OAT and altimeter setting Bank angle and weight effects on stall speed Wind correction Clean, dark instrument-panel interface For pilots who plan ahead.
