A helipad is like a parking spot for helicopters. Just like cars have places to park, helicopters need special spots to land safely too. These spots are called helipads.
To help pilots know exactly where to land, helipads have special marks or symbols on them. Think of these marks as signs that tell the pilot what to do.
For example, the most common mark is a big letter 'H' painted in bright colors. The 'H' stands for helicopter. Pilots look for this big 'H' when they are flying because it shows them the best place to land.
Sometimes, there are also different colors or lights around the helipad that can help pilots see it better, especially when it's dark outside. This way, no matter where they are, pilots can find the helipad quickly and land safely.
So, these special marks are very important because they guide the pilots and make sure everyone stays safe during landings!
