| Endpoint | Price | What it answers |
|---|---|---|
GET /density-altitude | $0.02 | Density altitude from field elevation, altimeter setting and temperature, exact and by rule of thumb, with a performance flag. |
GET /fuel-time-distance | $0.02 | E6B arithmetic: give any two of distance, groundspeed and time for the third, plus fuel burn, reserve and range. |
GET /glide-ratio | $0.02 | Glide distance, time and sink rate from altitude above ground, glide ratio and best-glide speed, with headwind or tailwind. |
GET /isa-atmosphere | $0.02 | Standard atmosphere at an altitude: temperature, pressure, density, sound speed, and ISA deviation for a measured temperature. |
GET /pressure-altitude | $0.02 | Pressure altitude from field elevation and altimeter setting (inHg or hPa), exact ISA result and the 1000 ft per inHg rule. |
GET /true-airspeed | $0.02 | True airspeed, Mach and equivalent airspeed from calibrated airspeed, pressure altitude and outside air temperature. |
GET /turn-hold | $0.02 | Turn rate, radius, bank angle and load factor from true airspeed, plus holding pattern leg length, width and time. |
GET /wind-components | $0.02 | Headwind or tailwind and crosswind (left or right) from wind direction and speed against a runway number or heading, with gusts. |
GET /wind-triangle | $0.02 | E6B wind triangle: wind correction angle, heading and groundspeed for a course, or track and groundspeed for a heading flown. |

Flight-planning calculators using the ICAO standard atmosphere and standard E6B formulas on the numbers you enter, provided as is. They are study and planning aids, not a substitute for the aircraft flight manual, approved performance data, current weather, NOTAMs or a flight instructor. Never base a go or no-go decision on this alone. Every paid response carries a disclaimer field.
