Changelog myclimate API

Version 2.0 - March 2025

Flight Calculator

New Feature

Bulk Flight Calculator:

  • Added a new aircraft_type parameter to indicate the type of aircraft used in bulk calculations for each flight segment.

Single Flight Calculator:

  • Added new parameters: aircraft_type_leg1, aircraft_type_leg2
  • aircraft_type_leg1 corresponds to the aircraft used for the flight from origin to destination.
  • aircraft_type_leg2 corresponds to the aircraft used if the flight involves a transfer (via) between two legs.
  • If the aircraft type is unknown, the API will return "other."
  • If no aircraft type is provided, the API will return "not_specified."
  • Both aircraft_type_leg1 and aircraft_type_leg2 can either be specified or left empty, depending on flight specifics.
  • If there is no transfer leg (via), aircraft_type_leg1 will be used exclusively.
