| - | The transitionLevel.xml file is used to calculate the transition level (TRL) and the transition altitude (TA) for each airport. | ||
| - | |||
| - | The ''transition level.xml'' file is located in the ''fir/'' directory | ||
| - | |||

| - | |icao|string|airport icao code, selects every airport starting with this (partial) ICAO code| | ||
| - | |default|boolean|the default transition level to use| | ||
| - | |||
| - | |||
| - | The icao attribute can be a full 4 character ICAO airport designator or a partial code which will select multiple airports. | ||
| - | |||
| - | === example ICAO attribute === | ||
