Find IATA and ICAO airport codes by code or place, with ranked matches from built-in or broader registry data plus nearby distances.

Calculate anchor rode length with tide and bow-height allowances, then check whether the rode you carry meets your chosen scope.

Estimate bilge pump delivery after lift and hose losses, then compare net removal and clearing time against a declared steady inflow.

Estimate boat range and departure fuel from measured cruise burn, with reserve and unpumpable fuel allowances for one-way or return trips.

Plan front and rear cold tire pressure from placard values and trip load with axle-share, temperature-change and equipment-limit checks.

Compare annual driving and transit costs across hybrid schedules, including cash expenses, time value, and current US mileage-rate proxies.

Size an EV charger circuit from EVSE current and check breaker fit, panel capacity plus conductor ampacity and long-run voltage drop.

Estimate reserve-aware EV range from usable battery energy and route consumption, then check trip margin and modeled arrival charge.

Estimate EV charging time from battery and power limits with taper and losses, then check added range, session cost and departure fit.

Price a field-service trip from travel and onsite costs, then apply margin with minimums, timing premiums and a repair-credit policy.

Find vessels in a Finnish AIS snapshot by identity or radius and review reported motion, position quality, speed bands and map context.

Check one flight and departure date against sample or provider data, then compare schedule differences and select the matching carrier route.

Estimate flight CO2e from airport codes or manual distances and compare cabin, fuel and radiative-forcing scenarios with a leg-by-leg audit.

Track an aircraft from an OpenSky state-vector snapshot and verify callsign or ICAO hex matches before comparing position, motion and freshness.

Convert MPG (US), L/100 km, and km/L with reciprocal formulas, clear direction guidance, and warnings for unusual or mistyped readings.

Calculate MPG, L/100 km, and km/L from one matched trip or fill-up, then estimate fuel cost, tank range, and a reference gap.

Calculate apparent propeller slip by comparing measured and theoretical boat speed, with an optional range based on speed uncertainty.

Practice 25 common US MUTCD regulatory and warning signs with repeatable rounds, immediate feedback, and focused review of misses.

Check Swiss station departures or arrivals with public timetable data and follow platform, delay, and route-stop changes for one service.

Plan cargo tie-down count and capacity from weight, WLL, strap path, blocking, and length rules with weak-link and margin checks.

Calculate trailer cargo capacity from GVWR and measured weight, then compare reserve, axle and tire limits to find the controlling margin.

Calculate trailer tongue weight from direct or lever readings and vehicle-scale tickets with checks for balance, hitch capacity and payload.
