What Does HTHL Stand For?

HTHL stands for Horizontal Takeoff Horizontal Landing

HTHL, or Horizontal Takeoff Horizontal Landing, refers to a type of aircraft operation where an aircraft is capable of taking off and landing while maintaining a horizontal orientation. This operational mode is commonly associated with certain unmanned aerial vehicles (UAVs) and advanced aircraft designs that utilize conventional runway operations, allowing for greater efficiency in flight operations and enabling the use of existing airport infrastructure. HTHL aircraft are characterized by their ability to transition smoothly between ground movement and aerial flight, providing versatility in various applications.
