Headwind: E6B Flight Computer

Headwind is an E6B flight computer and aviation calculator for student pilots, instructors and anyone who flies, with a crosswind calculator, wind triangle and fuel free, and density altitude with Pro. Every calculator solves as you type: no "=" key, no modes, big readable numbers.

FREE
• Wind triangle: true heading, wind correction angle and ground speed for a course, with a vector diagram
• Find the wind from heading, true airspeed, track and ground speed
• Runway wind: headwind or tailwind and crosswind for any runway, gusts included, checked against your crosswind limit
• Time, speed and distance: give any two, get the third
• Fuel: fuel needed, endurance or burn rate, with fuel weight for avgas or Jet A
• Cloud base from temperature and dew point
• Conversions: speed, distance, altitude, temperature, pressure, fuel, weight

HEADWIND PRO, ONE PURCHASE
• Pressure altitude and density altitude, with the rules of thumb next to the exact answer
• True airspeed and Mach from calibrated airspeed
• Weight and balance: your own aircraft, loading stations, fuel, CG envelope chart and a clear within-limits check
• Nav log: heading, ground speed, time and fuel for every leg, with magnetic variation and totals
• Descent planning: top of descent, vertical speed needed, 3° glide path
• Turns and glide: turn radius, rate of turn, standard-rate bank, glide distance
• Holding entries: direct, teardrop or parallel, with a diagram

MADE FOR LEARNING
• "How it's calculated" under every result explains the formula behind it, the same triangle you draw on a manual E6B
• Tap any unit to switch it: knots, mph or km/h; feet or meters; °C or °F; inHg or hPa; gallons or liters; pounds or kilograms
• Works the same on phones and tablets, in 12 languages
