Catch a bad crosswind or leg-time assumption before engine start. E6B Pilot Flight Computer helps student pilots, CFIs, and other manual-planning pilots turn runway wind checks, wind previews, and nav-log cards into a faster preflight and teaching workflow without opening a full EFB. Use the free core to: - check runway crosswind plus headwind or tailwind components from manual wind and runway inputs - check density altitude from pressure altitude and outside air temperature before opening aircraft performance tables - preview wind correction angle, heading, and groundspeed from true course, true airspeed, wind-from direction, and wind speed - keep the workflow fully offline with no account, ads, or live EFB scope Unlock Nav-Log Cards to: - turn a wind leg into a full nav-log card with heading, groundspeed, leg time, and fuel required before reserves - save, pin, and reload local training or preflight cards on iPhone or iPad - share a plain-language training summary for debrief, lesson handoff, or planning notes - unlock the full student-pilot and CFI drill-card library for repeat runway, wind, and leg-time practice Why pilots keep it: - catch a runway-component or leg-time mistake before engine start - practice manual E6B thinking without rebuilding the same math in notes, spreadsheets, or browser calculators - hand off a clean training or debrief card instead of rewriting numbers - stay focused on one review-safe manual planning job instead of a broad aviation suite Important: Results are planning and training references only. Always verify runway choice, performance, fuel reserves, and operational decisions with your POH or AFM, current conditions, and pilot judgment. This app is not FAA-approved avionics and does not provide navigation, live weather, charts, flight-plan filing, or aircraft integration.

Zulu Time brings Zulu (UTC), local time, world-clock planning, UTC alarms, and original instrument-inspired displays together in one focused app. AT A GLANCE • View live Zulu and selected local time side by side. • Configure Zulu and local time independently: 24-hour, 12-hour, or military format, optional seconds, and separate date styles. • Detect your current time zone automatically and refresh it as needed, or manually choose from 111 countries/regions and 126 cities and aviation hubs. PLAN THE SAME MOMENT WORLDWIDE • Select an exact UTC date and time up to seven days ahead or behind. • Move by 15 minutes, one hour, or one day. • Compare the same moment across saved world clocks with UTC offsets, DST status, and day-boundary indicators. • Read ISO 8601, aviation DDHHMMZ, and YYDDD ordinal codes. ZULU ALARMS • Schedule alerts directly in UTC and review the local-time conversion before saving. • Create one-time, daily, or weekly alarms. • Choose sound on or off and snooze for 10 minutes. ORIGINAL THEMES • Choose from 17 brand-neutral designs: six modern aviation displays, seven premium analog dials, and four minimal themes. • Supported aviation themes can use the on-device compass for live heading; heading scales in other themes are decorative. • Premium dials display both Zulu and local time without covering the dial. IPHONE, IPAD & APPLE WATCH • Configurable Home Screen, Lock Screen, and StandBy widgets. • A full Apple Watch app with all 17 themes. • Zulu/local and Zulu/date complications. • Sync the selected place, time zone, theme family, and verified subscription status from iPhone.

The localized price and renewal terms are shown before confirmation, and the subscription can be managed or canceled in Apple Account settings. The aviation displays are visual clock themes only. They are not calibrated or certified flight instruments and must not be used for navigation. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
