Performance Take-off and Climb

Performance — Aircraft & Microlight Performance Calculator

Make better go/no-go decisions, whether you fly an aircraft or a microlight. Performance turns your manufacturer figures into real-world performance for the conditions of the moment.

INSTANT CALCULATIONS
Performance automatically computes:
• Takeoff distance adjusted to actual conditions
• Rate of climb corrected for density altitude
• Runway usage as a percentage
• Density altitude and pressure altitude (from QNH)
Just enter your manufacturer figures (standard-conditions takeoff distance and rate of climb) and the app calculates performance for your current altitude and temperature.

RUNWAYS, WIND & DECLARED DISTANCES
Pick your departure runway at a glance:
• To-scale runway diagram, oriented to north
• Wind fetched automatically (Open-Meteo), with headwind and crosswind components
• Per-runway magnetic variation (°T / °M toggle)
• Official declared distances: TORA, TODA, ASDA, LDA
• Recommended runway and wind-based ranking
Built for aircraft and microlights alike, on paved or grass strips.

SMART AERODROME SELECTION
Worldwide database of 29,000+ aerodromes:
• Search by ICAO code or name
• Aerodromes within 100 NM
• Favourites for quick access
• Field elevation and temperature loaded automatically
No more tedious manual entry.

AUTOMATIC GEOLOCATION
• Detects your position
• Elevation estimated via GPS or an elevation API
• Real-time local temperature
• Nearby aerodromes shown
• Works even offline (favourite aerodromes)

PILOT-FIRST INTERFACE
• Key results shown clearly
• Visual safety indicators (runway, climb)
• Colour-coded alerts for critical conditions
• Automatic phone / tablet layout

ACCURACY & RELIABILITY
• Proven method based on the Köch chart
• Density altitude from the standard ISA formula
• Validated correction factors
• Results recalculated in real time

MULTILINGUAL
• English and Français
• Automatic language detection

TECHNICAL
• Works partly offline
• Low battery use
• Real-time weather (Open-Meteo)

RESPONSIBLE USE
Performance is a decision-support tool. The pilot in command remains solely responsible for verifying all calculations, assessing flight conditions, making the takeoff decision and complying with the aircraft flight manual. All results are advisory and must be checked against your aircraft's official flight manual.

ONGOING DEVELOPMENT
amenai technologies keeps improving Performance: regular updates, new features driven by pilot feedback, and an up-to-date aerodrome database.
