E6BJet app for iPhone and iPad

E6BJet provides the functions of most professional aviation slide-rules, and adds advanced features: instant QNH-QFE conversion, Mach-CAS crossover altitude calculation, precision temperature corrections to altitude, temperature rise due to airspeed, and accurate weight/volume conversion for kerosene, wide-cut, and avgas fuels using actual density if available. 

E6BJet can determine sunrise/sunset and civil twilight times for any location on Earth, between years 1900 and 2999, and comes with a user-expandable database of aerodrome locations.

An appearance similar to modern aircraft flight guidance panels allows instant “what-if” calculations, and keeps all calculation parameters in view simultaneously.

New in Release 2.50, E6BJet now also computes turn radius, diameter and circumference, along with turn rate.

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.
