- Definição2
- A surface of constant atmospheric pressure that is related to a specific pressure datum, 1013.2 hectopascals (29.92 in. of mercury), and is separated from other such surfaces by specific pressure intervals. Each flight level is started in three digits that represent hundreds of feet. For example, flight level 270 represents a pressure altitude of 27,000 ft with the altimeter set at 1013.2 hectopascals (29.92 in. of mercury). Consecutive flight levels are separated by a pressure interval corresponding to at least 500 ft (150 m) in the standard atmosphere. This does not preclude reporting intermediate levels in increments of 100 ft (30 m).
