Free Aviation Tools & Calculators

Handy calculators for student pilots — and an interactive E6B flight computer you can spin like the metal one. All free, right in your browser.

E6B Flight Computer

An interactive circular slide-rule E6B — drag the dial like the real thing.

Block the pitot or static port and watch the airspeed, altimeter, and VSI fail — and learn why.

Move the aircraft, turn the OBS, and watch the CDI + TO/FROM — learn to read a VOR.

Move the aircraft and heading; watch the fixed-card ADF and RMI — relative vs magnetic bearing.

Field elevation + altimeter + temp → pressure & density altitude.

Runway + wind → headwind and crosswind components.

Add your stations → total weight, moment, and center of gravity.

Enter any airport code → current weather in plain English, plus the raw report.

How to read the Graphical Forecasts for Aviation — the clouds, turbulence, and icing layers for a preflight briefing.

Paste an ICAO NOTAM → Q-code, fields, and contractions decoded into plain English.

Searchable sectional & TAC legend — airports, airspace, NAVAIDs, obstacles, and what each color means.

Searchable enroute & approach legend — airways, MEA/MOCA, fixes, holds, and FAF/IAF/MAP/minimums.

Step-by-step lessons for every checkride maneuver (PPL, IFR, Commercial, CFI, CFII) with ACS standards.

Runways, frequencies, elevation, and live weather for ~2,000 US airports.

Quick 10-question quizzes by topic — ACS-aligned, instant score, no account.
