Calculate safe drone flight distances with RangeSight – a physics-based range calculator that shows you exactly how far your drone can fly and return home safely.

🚁 WHAT IS RANGESIGHT?

RangeSight answers one critical question: "Can my drone safely reach this location and return home?" Using advanced physics modeling, it calculates your drone's operational range based on real-world conditions like wind, temperature, battery state, and payload weight.

⚡ CORE FEATURES

PHYSICS-BASED RANGE CALCULATOR
• Out-and-back range calculations with return safety margins
• Bidirectional wind modeling (headwind vs. tailwind)
• Crosswind energy loss penalties
• Battery consumption modeling (hover, cruise, climb)
• Environmental efficiency factors (temperature, humidity, altitude)

INTERACTIVE RANGE VISUALIZATION
• Color-coded concentric range rings showing safe return zones
• Green (25%+ battery), Yellow (10-20%), Red (under 10%)
• One-way maximum range indicator
• Wind direction arrow overlay

COMPREHENSIVE DRONE DATABASE
• 30+ pre-loaded profiles for DJI, Autel, Skydio, Parrot, and more
• All drone models available for free
• Battery cycle degradation tracking

⭐ PRO FEATURES

LIVE WEATHER INTEGRATION
• Real-time wind speed, direction, gusts, temperature, and humidity
• Weather data updates on-demand for any location
• Manual weather entry available for free

CUSTOM DRONE BUILDER
• Build a custom profile tuned to your exact aircraft
• Simple mode for quick setup or Advanced mode for full control
• Enter motor specs, propeller size, frame weight, and battery details

PAYLOAD SUPPORT
• Add payload weight for more accurate range calculations

OFFLINE MAPS
• Download map tiles for offline use in remote areas
• Multiple map styles: Street, Satellite, Terrain
• Dual-slot storage (switch between two regions)

ADVANCED CALIBRATION
• Fine-tune calculator with actual flight test data
• System adjusts predictions for your specific drone

SAVED HOME LOCATION
• Save home coordinates so you never have to re-enter them

ADDITIONAL TOOLS
• GPS coordinate auto-detection and manual coordinate entry
• Multiple map styles (day/night street, satellite, terrain)
• Imperial and metric unit support

🔒 PRIVACY & SECURITY
• No account required
• No tracking, no ads
• Location data stored locally only
• All connections use HTTPS encryption

⚙️ HOW IT WORKS
1. Select your drone model (or build a custom profile)
2. Enter or fetch live weather conditions
3. Set altitude, cruise speed, and/or payload weight
4. View color-coded range rings on interactive map
5. Plan flights within safe return zones

⚠️ IMPORTANT
• Always check NOTAMs and airspace restrictions
• Comply with all local drone regulations
• This is a planning tool, not autopilot software

🛠️ REQUIREMENTS
• Android 7.0+ • GPS • Internet for weather/maps • Offline mode available

Built for pilots, by pilots. Fly confident. Know your range. RangeSight.
