Flight Planning
Leg Planner
Complete flight leg planning with course, fuel consumption, waypoints, and time estimates. Perfect for VFR navigation
Course Calculator
Calculate wind correction angle, ground speed, and compass heading. Simple and focused on basic course calculations
Route Calculator
Calculate distance, true bearing, magnetic heading, and variation using WGS-84 geodesic algorithms for high-precision navigation
Flight Planning
Calculate time, speed, distance and fuel consumption. Solve any flight planning problem by entering two known values
Local Chart
Create printable route charts with fixed UTM scale for short-range local flights. Measure distances with ruler like a real aeronautical chart
Aircraft Performance
Climb Calculator
Calculate climb time, distance, fuel consumption, and Top of Climb position based on aircraft performance and density altitude
V-Stall Calculator
Calculate stall speed (IAS and TAS) adjusted for weight, bank angle, flap configuration, and density altitude. Essential for safety margins
Takeoff Performance
Calculate ground roll, obstacle clearance distance, and GO/NO-GO decision based on runway length, surface, weight, altitude, and temperature
Utilities
Unit Converter
Convert aviation units including distances, speeds, fuel volumes, temperatures, weight, and pressure. Inspired by the Jeppesen CR-3
TAS Calculator
Calculate True Airspeed from Calibrated Airspeed, Outside Air Temperature, and Pressure Altitude using the ISA model
ISA Calculator
Calculate ISA Temperature, Pressure Altitude, and Density Altitude from elevation, QNH, and actual temperature
Educational
Experimental aviation calculators based on ISA standard atmosphere, WGS-84 geodesic algorithms, and wind triangle principles. Plan complete flight legs with waypoints, ETAs, and fuel consumption. All calculations are performed client-side for instant results.
