Flight Level 255 corresponds to how many feet?

• A. 25,500 feet
• B. 25,000 feet
• C. 25,750 feet
• D. 26,000 feet

Answer: (A)

Flight levels are expressed as a pressure altitude using standard pressure, with the number representing hundreds of feet. That means to convert the flight level to feet you multiply the level by 100. So, a flight level of 255 is 255 × 100 = 25,500 feet. This value is the pressure altitude under standard conditions; actual altitude above mean sea level can differ if the atmospheric pressure isn’t standard. The other options don’t fit because they’re not the result of multiplying 255 by 100.
