Crosswind Calculator
A 20 knot wind sounds manageable until you learn how much of it is actually pushing you sideways toward the runway edge.
Crosswinds, takeoff runs, glide distances and descent rates — the pre-flight figures pilots work out before leaving the ground. Short tools for the numbers that sit between the weather report and the runway.
Takeoff and landing dominate the set. The Crosswind Calculator, the Takeoff Distance Calculator, the Glide Distance Calculator and the Descent Rate and Turn Rate Calculators all feed the same planning question: can this aircraft, on this day, use this runway safely? Pressure altitude and flight length sit alongside them, adjusting performance for the air itself rather than the airframe.
Two tools round out the shelf from different angles. Wing area covers the airframe side, and overflight fees cover the cost side — the charges for crossing airspace that turn up in flight planning budgets. Together they make a small but focused collection for pilots and flight planners.

Pressure altitude is the altitude your altimeter reads with 29.92 inHg in the Kollsman window: the height of the standard-atmosphere pressure surface above you.
Despite the name, this tool measures one thing and measures it well: the great-circle distance between two points on Earth, worked from their latitude and longitude with the haversine formula.
Wing area is the planform area of a wing, the outline you see looking straight down at it.
Turn rate means three different things, and mixing them up is the usual mistake.
Planning a descent is simple arithmetic, but doing it in your head while flying is how pilots end up high and fast on final.
Overflight fees are the toll booths of the sky: most countries charge every aircraft that crosses their airspace without landing, and the bill…
When the engine goes quiet, altitude becomes distance.
A runway that looks generous on a cool morning can turn marginal on a hot afternoon at elevation.
