  "id": "MLC-T-MET-005623",
  "term": "Flight level",
  "field": "Meteorology and atmospheric science",
  "definition": "A nominal altitude of an aircraft, expressed in hundreds of feet, based on a standard atmospheric pressure setting of 1013.25 hectopascals (29.92 inches of mercury). This standardized reference allows for vertical separation between aircraft regardless of actual atmospheric pressure variations. For example, Flight Level 350 corresponds to 35,000 feet under standard conditions.",
