E6BJet

E6BJet does what most professional aviation slide-rules do, and adds advanced features for professional pilots flying modern jet aircraft: QNH-QFE conversion, precision temperature corrections to altitudes/heights, crossover altitude determination, and accurate weight/volume conversion for kerosene, wide-cut, and avgas fuels using actual density.  E6BJet also computes turn radius, diameter and circumference, along with turn rate. Thumbwheels/sliders are used to enter values, which is much faster than aligning discs, or typing in numbers. E6BJet can determine past, present and future sunrise/sunset and civil twilight times, for any location on Earth, between years 1900 and 2999. A user-expandable database of aerodrome locations is provided. An appearance similar to modern aircraft flight guidance panels allows instant “what-if” calculations, and keeps all calculation parameters in view simultaneously. Results are shown in most commonly-used aviation units at the same time, eliminating time spent on conversions. E6BJet can make full use of the altimeter function most iPhones provide, and act as a baro-recorder. E6BJet allows quick flight planning calculations for any aircraft, from sport aeroplanes to airliners, and handles calculations well into the supersonic jet range. It is ready for the next-generation of pilots and aircraft. No subscription required. Fully functional in airplane-mode. No in-app purchases needed. No analytics or tracking.
