FlightReady E6B is a modern flight computer with the most complete set of aviation functions, conversions, and utilities for planning and flying. WHY PILOTS USE FLIGHTREADY E6B • Accurate. Conversions use exact defined factors, and airspeed and altitude calculations use the full U.S. Standard Atmosphere, maintaining accurate calculations above 36,000 feet. • Explained. Every function and conversion has built-in help that describes what it calculates, how to use it, and the formulas and conventions behind it. • Fast. Star the functions you use most to keep them at the top of the main menu, and your favorites sync to your other devices through iCloud. Open functions from Search, Shortcuts, Control Center, the Lock Screen, or the Action button. • Easy to use. Change a field's unit from the menu beside it, and every related field on the screen follows. Results automatically carry over to related functions, reducing repeated data entry. • Night-flight friendly. Dark mode uses a red-shifted amber color scheme designed for use in a dark cockpit.

About

Sky Widgets

Smart, customizable avionics widgets and safety alerts: built by a pilot, for pilots. Have you ever made a mistake while flying? Could that mistake have been avoided if you had systems in place to inform you of an issue before it was too late? As the creator of Sky Widgets, I'll be the first to say yes. I've forgotten to raise my flaps until I've already oversped them, landed with a tailwind when I didn't mean to, and even accidentally closed a fuel valve before opening the other. While I continually strive to become a better pilot, I recognize that none of us are perfect. As a software engineer, I see the potential for technology to provide that extra layer in the Swiss cheese. Having access to the right data at the right time helps us make better decisions and ultimately improves the safety of flight. I believe so strongly in the mission of Sky Widgets that even while designing the avionics layout for my own plane, I intentionally left an empty area in my panel for an iPad to allow my vision of Sky Widgets to have a dedicated spot. Sky Widgets isn't a rigid, locked down UI that forces you into fixed layouts with features you don't need for your mission. You design your dashboards around what matters to you and when in your flight you need it. • Custom Flight Dashboards: Build personalized layouts for engine data, flight telemetry, and cockpit alerts without clutter. • Smart Conditional Triggers: Set custom logic and visual cues to catch critical flight parameter changes early. • Avionics Updates: Ever forgotten to copy over your avionics update files from your computer to your USB drive? Sky Widgets lets you use your phone instead to easily transfer these onto your USB drive. • Independent & Privacy-First: Built by a fellow pilot committed to making your flights safer. Your data stays on your device. Sky Widgets will never replace your primary instruments or your responsibility as PIC. Think of it as a customizable co-pilot in your flight bag, offering specialized monitoring and tools that traditional EFIs or EFBs leave out. Start building your first dashboard now.
