• Flight Computer (Analog E6B)

  A faithful, fully interactive analog flight computer: calculator side and wind side with rotating scales, slider and azimuth, usable by touch and mouse with zoom for dense scales.

  • E6B calculator-side arithmetic
  • Wind side: WCA, heading, groundspeed
  • Time-speed-distance and fuel on the circular slide rule
  • Unit conversions on the scales
  OpenAvailable

• Flight Computer (Digital)

  A complete electronic flight computer with organised categories, fast numeric entry, clear units, validation and explanations; shares its validated math with the analog E6B.

  • All E6B calculations in digital form
  • Conversions
  • Wind, airspeed, altitude and fuel problems
  OpenAvailable

• TAS / CAS / EAS

  Indicated, calibrated, equivalent and true airspeed relationships versus pressure altitude and temperature. Instrument and position corrections are never invented.

  • IAS to CAS to EAS to TAS
  • Mach number
  • Density ratio and compressibility
  OpenAvailable

• Wind Triangle Solver

  Desired track, true airspeed, wind direction and speed give wind correction angle, required heading and groundspeed, with draggable wind, airspeed and ground-track vectors.

  • Wind correction angle
  • Heading to hold a track
  • Groundspeed
  • Vector triangle geometry
  OpenAvailable

• Crosswind / Headwind Component

  Runway diagram with configurable runway heading and wind: crosswind and head/tailwind components, left or right, with clear units and sign conventions.

  • Crosswind component
  • Headwind and tailwind component
  • Relative wind angle
  OpenAvailable

• Time-Speed-Distance

  Distance, time, groundspeed and estimated time en route with a moving aircraft or distance timeline.

  • Time from distance and groundspeed
  • Distance from time and speed
  • Groundspeed from a timed leg
  • ETE and ETA
  OpenAvailable

• Fuel Planning

  Consumption, endurance, fuel remaining, trip fuel, reserve and segment planning; user assumptions, aircraft data and regulatory minimums are kept apart.

  • Fuel burn and endurance
  • Trip and reserve fuel
  • Segment totals
  OpenAvailable

• Turn Radius & Bank Angle

  Airspeed and bank angle give turn radius, rate of turn and the turn geometry drawn to scale.

  • Turn radius from speed and bank
  • Rate of turn
  • Load factor in a level turn
  OpenAvailable

• Standard Rate Turn

  Rate-one turn simulation: heading change over time, turn duration and the bank angle needed at each airspeed, with turn-to-heading practice.

  • 3 degrees per second
  • Bank for a standard-rate turn
  • Time to turn to a heading
  OpenAvailable

• Lead Radial / Turn Anticipation

  Speed, turn radius, bank and interception geometry give the lead distance and lead radial for arc and course intercepts.

  • Lead radial
  • Turn anticipation distance
  • Intercept geometry
  OpenAvailable

• Weight & Balance

  Loading with verified aircraft data (Cessna 172S POH): occupants, stations, baggage, fuel, empty weight and moment, centre of gravity on the envelope, in or out of limits.

  • Weight and moment arithmetic
  • Centre of gravity
  • Envelope limits
  OpenAvailable

• Takeoff & Landing Performance

  Genuine published performance tables: weight, pressure altitude, temperature, wind, runway and configuration give takeoff and landing distances with applicability restrictions.

  • Reading performance tables
  • Pressure altitude and temperature corrections
  • Wind and runway corrections
  OpenAvailable

• Climb Performance & Service Ceiling

  Rate of climb versus altitude, temperature and loading from aircraft-specific validated data; no generic estimates presented as approved figures.

  • Density altitude and ISA deviation
  • Moist-air correction with the dew point
  • Optional live METAR
  OpenAvailable

• Night Windows & UTC

  Sunrise, sunset and civil twilight for an airport or position, and the FAA, EASA and UK night windows side by side in Zulu and local time.

  • Sunrise, sunset and civil twilight
  • Night currency window versus night logging
  • Zulu and local time conversion
  • Aircraft lighting period
