Which type of helipad operates without hold lines?

Uncontrolled helipads operate without hold lines, as they are utilized in situations where there is no air traffic control present to manage the movements of aircraft. At these helipads, pilots are responsible for their own operations, including landing and taking off, and as such, there is no need for hold lines to signify a stop or waiting area prior to entering the active landing or takeoff area. This autonomy allows for more flexible operational procedures, accommodating various scenarios without the constraints of formal traffic management.

In contrast, controlled helipads are managed by air traffic control, which requires hold lines to ensure safe and organized movements of aircraft. Designated helipads also typically have defined operating protocols that may include hold lines to standardize operations. Emergency helipads, while they might be simple and less regulated than those that cater to routine traffic, generally have defined procedures in place as well. Therefore, it is the uncontrolled helipads that are specifically designed to function without these hold lines, emphasizing autonomy and direct pilot responsibility.
