## What is TrueCourse E6B Flight Computer?

TrueCourse is a modern E6B flight computer for student pilots, GA pilots, and CFIs — the digital "whiz wheel" you're taught to use for the FAA knowledge exam and every flight after it.

Every number is computed from validated, published formulas (FAA-H-8083 handbooks and the ICAO Standard Atmosphere) — so you can trust it on a checkride and in the cockpit. Buy it once. No subscription, no ads, no account, no network required.

WHAT IT SOLVES
• Wind triangle — heading, groundspeed, wind-correction angle, and crosswind/headwind components, with a live vector diagram. Derive winds aloft from measured track and groundspeed.
• True airspeed & Mach — TAS from CAS with pressure altitude and temperature; Mach and speed of sound.
• Altitude — density altitude, pressure altitude, true altitude, cloud base, freezing level, and pivotal altitude.
• Nav log — time, speed, and distance; ETE and ETA.
• Fuel — burn, endurance, specific range, and required fuel with weight.
• Climb & descent — required rate, top of descent, climb gradient (ft/nm · % · degrees), and glide distance.
• Weight & balance — CG and moment with an envelope check, plotted on a CG chart with takeoff-to-landing fuel-burn travel.
• Convert — the aviation units you actually use: kt, mph, nm, sm, km, ft, m, °C, °F, gal, L, lb, kg, inHg, and climb gradients.
• Clock & timer — Zulu and local time with a count-down timer.

BUILT FOR THE FLIGHT DECK
• A glass-cockpit design with large, monospaced, sunlight-legible readouts.
• A night (red-shift) mode that preserves your dark adaptation.
• Every input field shows its valid range, so you can't enter a value that doesn't make sense.
• Universal: one purchase runs on iPhone, iPad, and Mac, with a layout that adapts to each.

TrueCourse does one thing and does it honestly: give you a number you can rely on. Nothing to subscribe to, nothing phoning home.

For training and education — a study aid for the FAA knowledge exam and flight training. Not for navigation. Always cross-check critical calculations and follow your POH/AFM and regulations.
