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 β€’ Wind triangle (heading, ground speed, wind correction) β€’ True / calibrated / equivalent airspeed β€’ Density and pressure altitude β€’ Time / speed / distance β€’ Fuel burn, endurance, and range β€’ Standard atmosphere + lapse rate β€’ Compass + magnetic heading with deviation and variation β€’ Reciprocal headings, pivotal altitude, standard rate turns β€’ Off-course (1-in-60) corrections β€’ Climb / descent rates and ground distance β€’ Cloud base, glide distance, holding pattern entry β€’ Linear interpolation β€’ 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: β€’ VFR: 30-min day or 45-min night reserve, optional alternate β€’ 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 β€” VFR or IFR titled β€” 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 β€’ Works fully offline - no signal, no problem β€’ Optimized for iPhone and iPad with dark cockpit theme β€’ Adjustable font scale for kneeboard readability β€’ US or metric units, switch any time β€’ Save unlimited routes β€’ 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.

An E6B that shows its work. Rotate E6B Flight Computer does every calculation a mechanical E6B does β€” and then opens the result to show you the formula and each step with the numbers you entered, so you can check it instead of trusting it. That is the part a plastic disc and most apps leave out, and it is the part you need when you are learning. WHAT IT CALCULATES β€’ Wind triangle: ground speed, wind correction angle, true heading β€’ Unknown wind, from heading, course and the two speeds β€’ True and magnetic heading, with variation and deviation β€’ Time, speed and distance β€” to the second, not rounded to the minute β€’ Fuel burn, endurance and required fuel β€’ Crosswind and headwind components β€’ Pressure altitude, density altitude and true altitude β€’ True airspeed from indicated β€’ Rate of descent and top of descent β€’ Cloud base and freezing level β€’ Weight and balance: moments, centre of gravity and an envelope chart that tells you in or out β€’ Unit conversions, including negative temperatures BUILT FOR THE EXAM AND THE COCKPIT Wind, fuel and density-altitude problems appear on every FAA written. The calculators use the exact trigonometric formulas, so the answers do not drift the way a dial reading does β€” and the step-by-step breakdown is how you learn to produce the answer yourself when the figure is on the exam sheet. Everything runs on the device. No signal, no account, no sign-in. Nothing you type is ever transmitted. DESIGNED TO BE USED IN FLIGHT β€’ A keypad built for the job: large keys, decimals and negatives, and no hunting for a tiny "=" β€” results update as you type β€’ On iPad the keypad sits beside the fields instead of covering them β€’ Light and dark, readable in a bright cockpit β€’ History and favourites, so a cross-country you ran last week is one tap away β€’ Your own aircraft: enter the arms, moments and envelope from your POH and save the profile WHAT IT COSTS Five calculators are included at no charge, permanently. The rest unlock with a single one-time purchase β€” not a subscription, nothing to cancel, and it restores on every device signed in to your Apple ID. Built by Rotate, who make the FAA exam prep at rotatepilot.com. Questions, or an answer you think is wrong? hello@rotatepilot.com β€” send the numbers you entered and the answer you expected. Unlocking the full version is a one-time purchase, charged once to your Apple ID. It is not a subscription: nothing renews and there is nothing to cancel.
