Phase III the Sling load operation
A trained groundcrew will ensure phase 1 and two were performed correctly. A signal man will guide the aircraft using proper hand and arm signals. Once the hook up is complete the signal man will then signal for aircraft to take off ensuring the load is not suspended over anyone’s head
Three factors of in-flight stability
Proper weight minimum weight is 500 pounds and max weight cannot exceed aircraft lift or cargo hook capability
Proper drag surface- A nose down lift altitude is achieved by proper link called making load as aerodynamic as possible
Proper airspeed-determined by the aviation unit commander or the pilot in command
