Landing Performance

Landing performance tool provides for the detailed analysis of the landing performance capabilities of transport category aircraft.

Performance tool calculates landing performance parameters based on the aircraft manufacturer’s performance algorithms (Manufacturer-provided SCAP modules), operator-specified policies, and applicable regulations. Advanced optimization techniques are used in order to maximize performance.

Automatic Data transfer

Landing performance is designed to load data from virtual data bus automatically. Almost all pilot inputs are adjusted if EFF is available and flight is selected. These are the data which are transferred from virtual data bus.

  • Aircraft Registration
  • Airport
  • Runway
  • Wind direction & Speed
  • OAT (Outside Air temperature)
  • QN
  • LW (Landing Weight)

Pilot still may override any data.

Data Disagree Check (Arinc 429 wiring available)

Flight manager checks calculated landing data and entered landing data to the FMC (Flight Management Computer) automatically. System gives popup message if any data differs. Arinc 429 wiring connection should be available for disagree check. These are the data which will be checked for landing performance disagree condition.

  • Landing weight
  • Selected Flap/Config
  • Vref

Tracked Data

Landing performance results are kept in memory for further research or investigate. These tracked data are sent to the dedicated server automatically when internet connection is available.
Database Updates

Landing performance tool uses three databases for calculation:

  • Manufacturer SCAP database
  • Company limits and parameters database
  • Airport & Obstacle database

All these databases are checked automatically for any updates. Automatic update check process starts when pilot login the system. Updated data are listed to inform pilot when requested.


  • User friendly standardized module that is same for all aircraft types,
  • Check the consistency and validity of the pilot‘s input and constrain it,
  • Input runway shortening,
  • Cover all MEL/CDL items, that effects landing performance and check the user‘s input of MEL/CDL,
  • Provide Airport/Runway/EOSID database and periodically update for database,
  • Computation for actual autobrake landing distances / far landing field required distances, vref
    speeds, landing / approach climb gradient, go around N1/EPR, One Engine-out special procedure (EOSID),
  • Same computations are provided for abnormal / non-normal conditions.
