EF1 E6B is a complete electronic flight computer built for student pilots, CFIs, and certificated pilots who want a fast, offline, modern E6B without the bloat. EVERYTHING AN E6B DOES - FASTER • Wind triangle (heading, ground speed, wind correction) • True / calibrated / equivalent airspeed • Density and pressure altitude • Time / speed / distance • Fuel burn, endurance, and range • Standard atmosphere + lapse rate • Compass + magnetic heading with deviation and variation • Reciprocal headings, pivotal altitude, standard rate turns • Off-course (1-in-60) corrections • Climb / descent rates and ground distance • Cloud base, glide distance, holding pattern entry • Linear interpolation • Universal converter (length, mass, volume, speed, temp, pressure) CROSS-COUNTRY PLANNING Build a full multi-leg route with up to 20 checkpoints. Set true course, distance, wind, TAS, fuel rate, MSA, and frequencies for each leg. Drag to reorder, duplicate, or reverse the route in one tap. Choose VFR or IFR mode and the app applies the correct FAR fuel rules: • VFR: 30-min day or 45-min night reserve, optional alternate • IFR: 45-min reserve, alternate-required toggle, alternate fuel auto-computed from distance to alternate Trip totals show ETE, ETA, fuel legality (LEGAL or NOT LEGAL with margin), and per-leg fuel remaining. PRINTABLE NAV LOG Generate a clean PDF nav log — VFR or IFR titled — with every checkpoint, fuel breakdown, frequencies card, and a side panel showing usable fuel, taxi, climb, enroute, alternate, and reserve. Email, print, or save it. FLY THE CROSS-COUNTRY Tap START FLIGHT, then mark off each checkpoint as you pass it. The app records actual time enroute, actual ground speed, and ATA, then writes them back into your post-flight log automatically. WEIGHT & BALANCE Build aircraft profiles, enter station moments, and check CG against the envelope. DESIGNED FOR PILOTS • Works fully offline - no signal, no problem • Optimized for iPhone and iPad with dark cockpit theme • Adjustable font scale for kneeboard readability • US or metric units, switch any time • Save unlimited routes • Backup and restore your data SUBSCRIPTION The EF1 E6B unlocks all features with a 7-day free trial, then $3.99/month or $19.99/year.
