Cielo vs EF1 E6B Flight Computer

Cielo is the complete pilot toolbox for iPhone; built by a pilot, for pilots. Whether you're preflight planning at home or running quick calculations in the cockpit, Cielo has everything you need in one clean, fast app. LIVE WEATHER MAP See nearby airports color-coded by flight category — VFR, MVFR, IFR, and LIFR — on an interactive map. Tap any airport to get a full weather brief: decoded METAR, TAF forecast, cloud layers with altitudes, wind components, runway layout with live wind indicator, com/nav frequencies, and sunrise/sunset times. 19 AVIATION CALCULATORS More features than a CX-3, for a much lower price! • Atmosphere: Pressure & Density Altitude, True Airspeed, Cloud Base Estimator, ISA Deviation, Mach Number • Navigation: Wind Components, Top of Descent, Speed/Distance/Time, Holding Pattern Entry, Vertical Navigation (VNAV), Glide Distance • Flight Planning: Heading & Ground Speed (wind triangle), Compass Heading Converter • Fuel: Fuel Planning with endurance and reserves • Weight & Balance: Total weight and CG calculator • Performance: Chart Interpolation (single and double) • Conversions: Aviation unit conversions • Reference: Flight Timer with lap recording, V-Speeds Every calculator includes a formula explanation so you understand the math, not just the answer. FLIGHT PLANNING Build multi-leg nav logs with distance, course, and wind for each leg. Cielo computes the wind correction angle, heading to fly, ground speed, leg time, and fuel — automatically. Save your plans and pull them up any time. CHECKLISTS Create fully custom checklists for every phase of flight: preflight, before takeoff, cruise, descent, landing, and shutdown. Organize items your way, check them off as you go, and reset for the next flight. Everything is saved across app launches. HOME SCREEN WIDGETS Add Cielo widgets to your iPhone home screen or lock screen for instant weather at a glance — current METAR conditions, flight category, and nearby airport weather — without even opening the app. V-SPEEDS & REFERENCE Store your aircraft's V-speeds from the POH for quick reference during preflight. No more flipping through pages or relying on memory. All calculators and widgets are available on the Free Tier. Cielo Pro unlocks the live weather map, flight planning, and checklist features.

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.
