Calculator for Flight vs E6B Flight Computer CFI Pilot

Calculator for Flight: The calculation of time, as well as commonly used in the calculation of the flight.In particular non-precision approach (VOR/DME, NDB/DME, LOC) for the descent profile calculation, making a more accurate non-precision approaches. It's free to get registration key. I would like to know how many people use this software. If you don't want to register, just click "continue", no function limitation. To Registration: 1.Figure 1, fill in the registration information. 2.Click "GetKey" to get key automatically, 3.then "Continue". 60进制计算器：主要用来累加飞行记录本中的飞行时间。 飞行计算器：提供60进制计算，以及飞行中常用的计算。 特别是非精密进近(VOR/DME,NDB/DME,LOC)的下降剖面计算，使得非精密进近更加准确。 注册是免费的。我只想统计一下有多少人使用这个软件。 注册方法： 1.如图1，填写注册信息。 2.点击"GetKey"获取注册码, 3.然后"Continue"。

E6B Flight Computer is the essential aviation calculator for student pilots, CFIs, and cockpit professionals. Built for PPL checkrides, cross country planning, and everyday flight operations — all offline, no internet required. AVIATION CALCULATORS 22 precision calculators covering every phase of flight: Wind & Navigation — Wind correction angle, heading & ground speed, crosswind & headwind components, course & distance between coordinates. Speed & Altitude — True airspeed (TAS), calibrated airspeed (CAS), density altitude, pressure altitude, true altitude, and cloud base estimation using ICAO standard atmosphere formulas. Fuel — Fuel required, endurance, point of no return, and equivalent still air distance. Performance — Weight & Balance with interactive CG envelope chart, top of descent, climb/descent gradient, and percent MAC. Time — Leg time, ETA calculator, and time/speed/distance solver. WEIGHT & BALANCE WITH ENVELOPE CHART Add crew, passengers, fuel, and baggage. The app computes total weight, total moment, and CG position — and plots it live on an interactive envelope chart. The tool every CFI recommends. UNIT CONVERSIONS 9 bidirectional converters: Temperature, Distance (NM/SM/KM), Speed (kt/mph/kph), Altitude (ft/m), Pressure (inHg/hPa), Weight (lb/kg), Volume (gal/L), Avgas weight, and Jet-A weight. COCKPIT CLOCKS & TIMERS Three simultaneous clocks — Zulu (UTC), Local, and Home timezone. Countdown timer with alarm, stopwatch with lap times for leg tracking. HOME SCREEN WIDGETS - Zulu Clock widget — always-on UTC time - Density Altitude widget — current conditions at a glance - Quick Converter widget LIVE ACTIVITY Flight timer countdown on your Lock Screen and Dynamic Island — no unlock needed. WORKS COMPLETELY OFFLINE No internet, no account, no server. Every formula runs on-device using pure ICAO Standard Atmosphere calculations.
