Flight Level
정의
A standard nominal altitude of an aircraft based on a standard altimeter setting (29.92 inHg / 1013.25 hPa). Flight Level 350 means 35,000 feet. Used above the transition altitude.

Transition Altitude
The altitude at which aircraft switch from using local altimeter pressure to the standard altimeter setting (29.92 inHg). Above this altitude, altitude is expressed as flight levels.
Airspace Classification
The categorization of airspace into classes (A through G) based on the level of air traffic control service provided and the flight rules that apply. Class A is the most restrictive.
Cabin Pressurization
The process of pumping conditioned air into an aircraft cabin to maintain a safe and comfortable air pressure for passengers and crew at high cruising altitudes.
