WindLimit vs SkewT Aero

WindLimit gives pilots a fast, clear answer to one question before every takeoff and landing: is this wind within limits? Enter your runway, wind direction, and speed, or pull live METAR for any of 12,700+ U.S. airports, and WindLimit instantly computes your headwind and crosswind components, checks them against your aircraft's limits, and flags an exceedance the moment you're outside them. FEATURES • Live METAR for public, private, and military airports nationwide, with automatic magnetic variation correction • Every runway end's crosswind and head/tailwind side by side, with the best end badged • Manual and ATIS entry when no live weather feed is available • Runway-aware exceedance alerts, keyed to the runway you actually pick • Set your own max demonstrated crosswind and personal minimums per aircraft • Clean, glanceable compass display with drag-to-set wind input • Light and dark themes WindLimit is a free, ad-supported informational tool. A one-time in-app purchase removes ads and unlocks: • Multiple saved aircraft profiles • Nearby airports with live wind, best runway, crosswind, and a within-limits read for each • Favorite and recently used airports IMPORTANT WindLimit is an informational aid only. It is not a source of official weather, performance, or limitation data, and must not be used as the sole basis for any operational decision. Always verify winds, runway conditions, and crosswind limitations against official sources: current ATIS/METAR, NOTAMs, and your aircraft manufacturer's or operator's current manuals and limitations. The pilot in command remains solely responsible for every operational decision. Designed by pilots.

SkewT Aero helps pilots truly understand the atmosphere and what that means for a planned flight. Explore weather along your route using interactive visualizations built directly from modern forecast guidance. Compare departure times, inspect hazards, and understand how clouds, winds, icing, turbulence, convection, ceilings, and visibility evolve before you fly. Every view is synchronized by route, time, and altitude. Move anywhere along your route or compare different departure times to see how the forecast changes throughout the flight. SkewT Aero complements tools like ForeFlight and Garmin Pilot by helping pilots explore forecast guidance in greater detail before making weather decisions. Features include interactive route weather visualization, route hazard timelines, vertical atmospheric profiles, forecast soundings (Skew-T), route stations, nationwide weather maps, operational NOAA forecast guidance, offline weather and navigation data, and hourly forecast updates. Forecasts are built from operational NOAA guidance including HRRR, RRFS, GFS, NBM, DAFS, and LAMP. Rather than reducing those models to a text briefing, SkewT Aero lets you interact directly with the atmosphere they predict. Whether you're evaluating today's flight or planning several days ahead, every view stays synchronized so you can quickly understand how weather changes with location, time, and altitude.
