Free pilot tools

Fast, no-signup flight-planning tools — the math checked against the handbooks. Built to be used on the ground before you fly.

E6B Flight Computer

live

For: Student · Pilot

The full flight-computer function set: unit conversions, time-speed-distance and fuel solvers, density altitude and TAS, the wind triangle with a live diagram, climb & descent gradients, and weight-shift math.

METAR Decoder

live

For: Student · Pilot

Fetch the live report for any airport, or paste a raw METAR, and read it in plain English — wind, visibility, ceiling, temperature, and a VFR/MVFR/IFR/LIFR call.

Fuel & Endurance

live

For: Student · Pilot

Usable fuel, burn, and cruise speed into endurance, still-air range, and a §91.151 reserve check — the numbers before the dipstick confirms them.

Weight & Balance

live

For: Student · Pilot

Load the seats, baggage, and fuel and watch the CG land inside — or outside — the envelope, on a live weight-vs-CG chart. A PA-28 example you edit for your aircraft.

Takeoff & Landing Performance

live

For: Student · Pilot

Density altitude, weight, and wind into ground roll and the over-50-ft distance, checked against your runway — the POH method, worked on a PA-28 example.

Go / No-Go

live

For: Student · Pilot

Ceiling, visibility, wind, and density altitude banded green/amber/red against your personal minimums — a one-look decision aid before you commit.

Compass & Instrument Errors

live

For: Student · CFI

The magnetic compass acceleration (ANDS) and turning errors, on a live card — plus a reference for the gyro and pitot-static instrument errors.

Crosswind Components

live

For: Student · Pilot

Set the runway and wind and read off the headwind and crosswind components, checked against your personal limit and the gusts.

More on the way

Still to come: a systems trainer. Live weather by airport is already in the METAR decoder above — type a station and fetch it.
