EF1 E6B Flight Computer

EF1 E6B is a complete electronic flight computer for student pilots, CFIs, and certificated pilots. Every E6B calculation, plus full VFR and IFR cross-country planning with a printable nav log — all offline, all in one app.

EVERYTHING AN E6B DOES

• Wind triangle: true heading, ground speed, wind correction angle
• True, calibrated, and equivalent airspeed
• Density and pressure altitude
• Time, speed, distance
• Fuel burn, endurance, range
• Standard atmosphere with lapse rate
• Compass and magnetic heading with deviation and variation
• Reciprocal headings, pivotal altitude, standard rate turns
• Off-course (1-in-60) corrections
• Climb and descent rates with ground distance
• Cloud base, glide distance, holding pattern entry (parallel, teardrop, direct)
• Linear interpolation
• Unit converter — length, mass, volume, speed, temperature, pressure

VFR AND IFR CROSS-COUNTRY PLANNING

Build a full multi-leg route — 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 and the app applies the right 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 PDF

Generate a clean PDF nav log — VFR NAVIGATION LOG or IFR NAVIGATION LOG, automatically — 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 captures actual time enroute, actual ground speed, and ATA, then writes them into your post-flight nav log automatically.

WEIGHT AND BALANCE

Build aircraft profiles, enter station moments, and check CG against the envelope.

DESIGNED FOR PILOTS
