JOINT SERVICE PARACHUTE CENTRE NETHERAVON

1. JOINT SERVICE PARACHUTE CENTRENETHERAVON

2. CANOPY CONTROL

3. The Aim To teach you how to achieve a SAFE controlled descent and landing

4. Ram AirParachuteSystem(RAPS)

5. Ram Air Parachute Characteristics Highly manoeuvrable Rectangular in shape Forward speed of 20 - 25 mph (depending on body weight) Turns quickly Can glide long distances

7. How the CanopyWorks Aerofoil shape - wing design Open cell front allows air to be rammed in Produces a Semi-rigid wing Low & high pressure create lift

8. Ram Air Parachute - Modes of Flight Toggle Toggle Toggle Full Drive Half Brakes Full Brakes

9. How The Canopy Turns Toggles are attached to steering lines Steering lines are attached to the tail

11. Full Depression Turns Rapid loss of height Dangerousclose to ground Continuous turns cause fast spirals

12. Warning Don,t spiral below 1500ft

13. Any Questions?

19. ANY QUESTIONS?

20. Flight Drills 1. Check canopy 2. Pump brakes twice 3. All round observation

21. LOOK UP AROUND DOWN

22. 4. Locate the DZ Not necessarily over the DZ Depends on wind speed Use reference points to locate DZ Move to holding area

26. HOLDING AREA

27. 5. Assess Drift Over holding / play area Hold into wind Assess the wind strength

28. ANY QUESTIONS?

29. Flight Drills 1.Check canopy 2. Pump brakes twice 3. All round observation 4. Locate the DZ(move to holding area) 5. Assess wind

30. Experiment If the wind conditions are not too strong, carry out the following exercises (over DZ) 360 left turn 360° right turn 3 practice flares

31. During Your Flight AlwaysRemember:- • All round observation • Altitude awareness • Location of the PLA

40. Landings Smooth flare from full flight (10 ft, 2 - 3 sec's from the ground)

41. If you flare too high - keep the toggles depressed & adopt the PLF position • If you flare too low - flare quickly & PLF

42. ANY QUESTIONS?

43. Flight Drills 1.Check canopy 2. Pump brakes twice 3. All round observation 4. Locate the DZ(move to holding area) 5. Assess drift

44. Experiment

45. The Landing Pattern

46. Turbulence Causes: thermals wind deflected over buildings Effects: canopy buffeting Cure: fly on third brakes until through turbulence

47. Common Problems (Nuisance Factors)

48. Toggle Released Prematurely Release other toggle and carry on with flight drills
