  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

  6. 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

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

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

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

  10. Warning Don,t spiral below 1500ft

  11. Any Questions?

  12. WindDriftIndicator Length & weight Thrown from 2500ft Simulates a student canopy J/M can determine the correct opening point

  16. HOLDING • RUNNING • CRABBING • WIND LINE

  17. ANY QUESTIONS?

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

  19. LOOK UP AROUND DOWN

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

  21. HOLDING AREA

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

  23. ANY QUESTIONS?

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

  25. 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

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

  27. The Landing Pattern

  28. LANDING PATTERN (left-hand circuit) Play Area (up wind)

  29. LANDING PATTERN (left-hand circuit) Downwind Leg 1000ft _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Play Area (up wind)

  30. LANDING PATTERN (left-hand circuit) Downwind Leg 1000ft _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Base Leg 500ft _ _ _ _ _ _ _ _ Play Area (up wind)

  32. UPWIND HOLDING AREA 1000FT DOWNWIND LEG

  33. UPWIND HOLDING AREA 1000FT DOWNWIND LEG 500ft BASELEG

  34. UPWIND HOLDING AREA FINAL APPROCH 1000ft DOWNWIND LEG 500ft BASELEG 300ft

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

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

  37. ANY QUESTIONS?

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

  39. Experiment

  40. The Landing Pattern

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

  42. Common Problems (Nuisance Factors)

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

  44. SLIDER UP PUMP TOGGLES TWICE

  45. END CELL, CLOSURE & SLIDER UP PUMP TOGGLES
