Kinematic aircraft performance database

As part of Open Aircraft Performance model, the WRAP database provides operational performance, flight envelopes of aircraft performance parameters. ADS-B data are use for model construction. Detailed methods and model description can be found in the paper.


Parameters

The parameters are defined by flight phases. The method to extract these parameters are define in the paper.

Takeoff
  • liftoff speed (to_v_lof)
  • takeoff distance (to_d_tof)
  • mean takeoff acceleration (to_acc_tof)

Initial climb:

  • cutoff altitude (1500 ft)
  • calibrated airspeed (ic_va_avg)
  • vertical rate (ic_vh_avg)

Climb:

  • range to the top of climb (cl_d_range)
  • constant CAS crossover altitude (cl_h_cas_const)
  • constant CAS (cl_v_cas_const)
  • vertical rate during constant CAS climb (cl_vz_avg_pre_cas)
  • constant Mach climb crossover altitude (cl_h_mach_const)
  • constant Mach number (cl_v_mach_const)
  • vertical rate during constant Mach climb (cl_vz_avg_mach_const)
  • vertical rate before constant CAS climb (cl_vz_avg_pre_cas)

Cruise:

  • cruise range (cr_d_range)
  • nominal cruise altitude (cr_h_mean)
  • maximum cruise altitude (cr_h_max)
  • nominal cruise Mach number (cr_v_mach_mean)
  • maximum cruise Mach number (cr_v_mach_max)

Descent:

  • range from the top of descent (de_d_range)
  • constant Mach number (de_v_mach_const)
  • constant Mach descent crossover altitude (de_h_mach_const)
  • vertical rate during constant Mach descent (de_vz_avg_mach_const)
  • constant CAS (de_v_cas_const)
  • constant CAS crossover altitude (de_h_cas_const)
  • vertical rate during constant CAS descent (de_vz_avg_cas_const)
  • vertical rate after constant CAS descent (de_vz_avg_after_cas)

Final approach:

  • cutoff altitude (1500 ft)
  • calibrated airspeed (fa_va_avg)
  • vertical rate (fa_vh_avg)

Landing:

  • touchdown speed (ld_v_app)
  • breaking distance (ld_d_brk)
  • mean breaking deceleration (ld_acc_brk)
