What altitude does FL195 indicate?

Flight Level 195 (FL195) indicates an altitude of 19,500 feet. The "FL" designation is a standard term used in aviation to denote flight levels, which represent the altitude at which an aircraft is flying in relation to standard atmospheric pressure. Each flight level is expressed in hundreds of feet; therefore, FL195 equates to 19,500 feet. This classification is crucial for air traffic control, as it helps maintain safe vertical separation between flights in the airspace. Understanding this terminology is essential for ATC trainees as it directly pertains to how they communicate altitude information during flight operations.
