Point-in-Space Approach
A Point-in-Space (PinS) approach is a helicopter instrument procedure that involves flying towards a designated location in space rather than towards a runway or landing area. This type of approach is often used when helicopters need to land in remote or rugged terrain where conventional approaches may prove difficult or impossible.
In a PinS approach, the helicopter follows a predetermined flight path towards a missed approach point (MAP) which is located more than 2,600 feet from the landing area. The MAP is a virtual point in space that marks the end of the approach phase and the beginning of the missed approach phase, should the pilot decide to abort the landing.
During the approach, the pilot references a navigation aid or GPS system that provides real-time position information to maintain proper course and altitude. The approach is completed when the helicopter reaches the MAP, at which point the pilot will either continue with the landing or transition to a missed approach and climb to a safe altitude.
Overall, the Point-in-Space approach offers more flexibility and precision for helicopter operations, especially in challenging environments. It requires a certain level of skill and training on the part of the pilot to execute the maneuver safely and effectively.
