FL260 refers to a flight level of 26,000 feet above sea level. In aviation, flight levels are used to indicate altitude in a standardized way, typically measured in hundreds of feet. This specific altitude is often used by commercial airlines and private aircraft during cruising phases of flight. At FL260, aircraft are usually above most weather disturbances and can enjoy smoother air. This altitude is also within the range of many regional air traffic control sectors, allowing for efficient management of air traffic. Pilots must adhere to specific regulations and procedures when operating at this flight level to ensure safety and compliance with FAA guidelines.
