 "description": "Crabwise is an E6B flight computer for iPhone, built for student pilots, private pilots and CFIs who want the answer and the working behind it.\n\nWIND TRIANGLE (FREE)\n• Find heading: enter TAS, true course and the wind to get wind correction angle, true heading and ground speed\n• Find wind: enter heading, TAS, track made good and ground speed to back out the wind you actually flew in\n• A live vector diagram shows the air, wind and ground legs of the triangle\n\nUNIT CONVERSION (FREE)\nNautical miles, statute miles and kilometers; knots, mph and km/h; pounds and kilograms; US gallons and liters; °C and °F; inHg and hPa; feet and meters. Fuel weight for avgas (6.0 lb/US gal) and Jet-A (6.7 lb/US gal).\n\nCROSSWIND BEFORE YOU LAND\nEnter the runway number and the tower or ATIS wind. Crabwise shows the crosswind from the left or right, the headwind or tailwind, and the components in gusts.\n\nALTITUDE AND AIRSPEED\nPressure altitude from field elevation and altimeter setting, the way the FAA knowledge test expects it. Density altitude from the full ISA density ratio, not the 120 ft per degree rule of thumb. True airspeed from calibrated airspeed with compressible flow, and Mach number.\n\nTIME, SPEED, DISTANCE AND FUEL\nSolve for whichever one is missing. Fuel burn, fuel flow, endurance, and total required fuel with taxi, run-up and reserve. Use gallons, liters or pounds.\n\nWEIGHT AND BALANCE\nAdd stations with weight and arm, get moments, total weight and center of gravity. Enter the corner points of the CG envelope from your POH and see at once whether you are inside it.\n\nSEE EVERY STEP\nEach result can open into the formula and the numbers substituted into it, the way you would work it on a paper E6B. Useful for the written exam, the oral and the checkride.\n\nPRIVATE AND OFFLINE\nEvery calculation runs on your iPhone. No account, no ads, no tracking, and no signal needed. Light and dark themes.\n\nFREE AND PRO\nFree: wind triangle (find heading and find wind) and unit conversion.\nPro: crosswind, time-speed-distance, fuel, altitude and airspeed, weight and balance, and step-by-step solutions for every calculator.\n\nCrabwise Pro is available weekly, monthly or yearly, or as a one-time lifetime purchase. The yearly plan starts with a 7-day free trial. Payment is charged to your Apple Account at confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before that. Manage or cancel them in your App Store account settings. The lifetime purchase is a single payment and does not renew.\n\nNot for navigation. Crabwise is for training and reference only. Always cross-check with your POH, approved charts and official sources. Crabwise is not affiliated with or endorsed by the FAA.\n\nTerms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/\nPrivacy Policy: https://vomcore.com/crabwise/privacy",
