Every calculator lives under one of six categories. Pick one to jump straight to the tools you need.
Complete guides
Long-form references that go deeper than a single calculator — the concepts, formulas and real-world judgment behind each number.
Everything a flight starts with
One modular toolkit covering the numbers you check before every leg — weather, fuel, weight, and performance.
Crosswind & Density Altitude
Resolve headwind and crosswind components instantly, and get density altitude corrected for temperature, pressure, and field elevation.
Fuel Burn & Range
Plan reserves against burn rate, distance, and headwind before you file.
Weight & Balance
Plot loaded CG against the envelope for your airframe in seconds.
True → Magnetic
Convert headings with live variation lookups by region.
Takeoff & Landing Distance
Runway-length checks adjusted for weight, wind, slope, and surface condition, cross-referenced against POH tables.
All 50 calculators
All 50 are live and fully working right now — every one built to FAA/ICAO reference formulas with a full worked-example page. Filter by category below.
Three steps, every time
Every calculator in the toolkit follows the same flow — no learning curve between tools.
Built like a cockpit, not a spreadsheet
A look at the kind of insight the toolkit surfaces — usage, response time, and formula coverage across every category.
What pilots use it for
"I run the crosswind numbers before every pattern lesson with students — it's faster than the E6B and just as accurate."
"Density altitude at a hot, high field is the first thing I check. This gets me the number in seconds, cockpit-side."
"Weight and balance for a fully loaded 172 used to mean a paper worksheet. Now it's two minutes on my phone before startup."
