What are the dimensions of the code letter?

The dimensions of the code letter are specifically defined as 35 feet by 35 feet. This standard is important for jump operations as it provides a clear and recognizable target area for parachute landings. The size of the code letter ensures that it can be seen from a considerable height and distance, facilitating accuracy in landing and enhancing safety for jumpers. Having a uniform size for the code letter helps in maintaining consistency across different operational scenarios, allowing jumpers to quickly identify the landing area. The other choices, while they might seem plausible, do not conform to the established specifications for the code letter used in parachuting operations.
