=== NaviGuard === An Innovative Flight Safety Feature for Pilots and Operators In today's world of advanced technology and GPS-dependent navigation, pilots and flight operators need a reliable solution to ensure the accuracy and safety of their flight paths. Aircraft Performance Group is proud to offer NaviGuard, a unique feature designed to enhance the navigation capabilities of our flight planning applications. NaviGuard is specifically developed to help users avoid reported areas of GPS interference, detect anomalous GPS readings on their iPads, and validate GPS data using radio navigation. This feature offers pilots improved safety and precision during planning and in flight. == KEY BENEFITS OF NAVIGUARD == -- ANTICIPATE PROBLEMS -- Real-time monitoring of problem areas, enabling pilots to foresee and circumvent issues stemming from GPS spoofing and jamming before they occur -- SET ACTIVE ALERTS -- Proactive in-app notifications that alert pilots of known danger zones during flights, presenting the option to reroute or proceed with complete awareness of potential hazards. -- PLOT & CONFIRM -- In-flight GPS coordinate verification by mapping relative to Navigational Aids (NAVAIDs), removing any uncertainty about location accuracy.

E6B Max is the modern flight computer for student pilots and GA aviators — the classic E6B whiz‑wheel plus the planning tools you actually use, all in one clean, easy app. FLIGHT COMPUTER - Time, speed & distance - Fuel burn & endurance - True airspeed, pressure & density altitude (from your altimeter setting) - Altitude correction — true altitude for non‑standard temperature - Wind triangle with true, magnetic & compass headings - Temperature slide (°C ⇄ °F) A photorealistic, hand‑turnable slide‑rule dial mirrors every calculation — type a value to turn the wheel, or drag the wheel to set it. The center hub recreates the real E6B correction window, with concentric pressure‑altitude, air‑temperature and density‑altitude scales. Pinch to zoom in on the fine graduations. The wind side is a true sliding‑grid plotter for the manual method. NAV LOG - A dead‑reckoning flight plan you can fill out or auto‑populate - Type From/To and a cruise altitude, then tap to auto‑fill course, distance, magnetic variation (World Magnetic Model), winds aloft and true airspeed - Per‑leg magnetic/compass heading, ground speed, ETE, ETA (Zulu and station‑local), ETR (time remaining) and fuel — with running totals - Enter a Zulu departure time (or Start now) for real clock ETAs; add beginning fuel and climb time/fuel for fuel remaining at every checkpoint - Auto‑fill or Manual — every value stays editable; record optional in‑flight actuals - Export a clean, gridded PDF nav log to share, save or print - Live LOCAL and ZULU clocks, a stopwatch, and a countdown timer WEIGHT & BALANCE - Save a profile per tail number - Custom stations, plus ramp / takeoff / landing / zero‑fuel weight limits - Anything over a limit turns red, with a CG envelope plot - Export a weight & balance PDF to share, save or print WEATHER & MAP - METAR, TAF & winds aloft — raw or plain‑English decoded - Type your cruise altitude to read the wind right at your level - Sunrise/sunset for each airport (Zulu in raw view, station‑local when decoded) - No TAF? The nearest reporting airport is shown with distance & bearing - Moving map with airports colored by flight category (VFR/MVFR/IFR/LIFR) - Plot your active nav‑log route with numbered checkpoints - Standard and satellite map views INSTRUMENTS - A sensor‑driven six‑pack: airspeed, attitude, altimeter, turn coordinator, heading & vertical speed - Set level to zero the attitude to your mount; adjustable barometric (Kollsman) setting in inHg or hPa MORE - Crosswind & headwind component calculator with a caution limit - Pre-flight risk assessment (FAA PAVE go/no-go) with a weighted score - Every aviation unit conversion - Live FAA regulations (14 CFR), always current from the eCFR - Emergency quick reference: lost comms, intercepts, light‑gun signals, squawk codes - Red/white night flashlight PRIVATE BY DESIGN No accounts. No ads. No tracking. Your profiles and trips stay on your device. A one‑time purchase — no subscription, ever. E6B Max is a planning and training aid, not a certified instrument or navigation source. Always verify critical information against current official sources and your aircraft's approved documents. You are pilot in command.
