? Limitations: engine and weight
? Route selection
Teaching Points
Show and describe the cargo hook fitted to the helicopter, together with the systems of arming, loading, release, emergency manual release, and emergency external release.
Show and describe the nets, straps, barrel hooks and any specialised equipment, together with the inspections for suitability and serviceability.
Describe, in detail, the procedures used in sling-load operations, including:
? pre-flight checks of the equipment
? briefing of ground crew
? hooking-up, with and without ground crew
? in-flight procedures, including emergencies
? release, with and without ground crew.
Students should be made aware of the possibility jettison the load and for this reason, routes should be selected over open country to minimise the danger of persons or property.
Explain that loads that are large in size relative to their weight can cause handling problems in forward flight. Describe the symptoms of load oscillation and how they can often be anticipated and stabilised before hook-up. Explain that should oscillations occur in flight they can often be minimised, either by an increase in power or a reduction in airspeed or by making gentle balanced turns.
If, despite all efforts to prevent or cure oscillations, they start to hazard the safety of the helicopter and crew, the pilot should be mentally and physically prepared to jettison the load before control is lost. This should also be an immediate reaction to an engine failure or similar in-flight emergency.
Explain the advantages of a well-sited mirror.
Point out the need for higher hover heights and modified approach and departure paths to maintain obstacle clearance, and the resultant extra power required.
AIR EXERCISE
Demonstrate pick-up and release procedures with ground crew.
Student practice
Demonstrate use of manual release, and external release by ground crew.
