To teach you how to achieve a SAFE controlled The Aim To teach you how to achieve a SAFE controlled descent and landing
Ram Air Parachute System (RAPS)
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
How the Canopy Works Aerofoil shape - wing design Open cell front allows air to be rammed in Produces a Semi-rigid wing Low & high pressure create lift
Ram Air Parachute - Modes of Flight Toggle Toggle Toggle Full Drive Half Brakes Full Brakes
How The Canopy Turns Toggles are attached to steering lines Steering lines are attached to the tail
Dangerous close to ground Continuous turns cause fast spirals Full Depression Turns Rapid loss of height Dangerous close to ground Continuous turns cause fast spirals
Warning Don,t spiral below 1500ft

ANY QUESTIONS?
Flight Drills 1. Check canopy 2. Pump brakes twice 3. All round observation
LOOK UP AROUND DOWN
Not necessarily over the DZ Use reference points to locate DZ 4. Locate the DZ Not necessarily over the DZ Depends on wind speed Use reference points to locate DZ Move to holding area
HOLDING AREA
Over holding / play area 5. Assess Drift Over holding / play area Hold into wind Assess the wind strength
ANY QUESTIONS?
4. Locate the DZ (move to holding area) Flight Drills 1. Check canopy 2. Pump brakes twice 3. All round observation 4. Locate the DZ (move to holding area) 5. Assess wind
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
During Your Flight All round observation Altitude awareness Always Remember:- All round observation Altitude awareness Location of the PLA

(10 ft, 2 - 3 sec's from the ground) Landings Smooth flare from full flight (10 ft, 2 - 3 sec's from the ground)
If you flare too high - keep the toggles depressed & adopt the PLF position If you flare too low - flare quickly & PLF
