General Guide • Intended to be deployed in event of a life threatening emergency • I.e., would you jump from the plane with a parachute? • Will most likely destroy the aircraft, may cause serious injury or death to occupants. • Hazards: • Ignition of rocket device • Lateral speed upon touchdown will equal wind speed • Aircraft may be dragged across ground after touchdown by wind • Chute may impede exiting aircraft • No control over landing site • Vertical speed equals vertical drop from 13’ • Irreversible!
Deployment Speed/ Altitude • Maximum deployment speed of 133 KIAS • At least one Cirrus accident aircraft deployed CAPS at very high speed, rumored over 200 KIAS, and chute separated from aircraft • If possible, slow as much as practical before deploying. • Do not delay if time or altitude critical! • No minimum altitude set • Demonstrated altitude loss: • In level flight <400’ • From entry into one turn spin, 1000’
Possible Deployment Scenarios • Midair collision • Structural failure • Flight control failure • Loss of control due to: • Wake turbulence • Severe turbulence • Spin • Landing in rough terrain • Pilot Incapacitation
Deploying CAPS • Airspeed Minimum Possible • Mixture Cutoff • CAPS Cover Remove • Activation Handle Pull Straight Down Clasp both hands around the T-handle and pull straight down with a steady force. Up to 45 lbs of force may be required. Do not jerk the handle, as it will greatly increase the force required to activate CAPS.
After Deployment • Mixture Confirm Cutoff • Fuel Selector Off • Bat-Alt Masters Off • Ignition Off • Boost Pump Off • ELT ON • Seat Belts Uncomfortably Tight • Loose Items Secure • Assume Emergency Landing Position Cross arms across chest and grasp shoulder harness. Hold upper torso erect against seat back.
Door Position • One or both doors may jam upon impact • May be advisable to open prior to impact • However, must consider: • Door may depart aircraft, • Head injury, • Injury from objects entering cabin • Exposed door pillar presents hazard
Deployment Above Water • Consider: • Exiting aircraft in water with jammed doors • Aircraft may sink quickly • Shock absorption of gear not fully available • In both CAPS deployment events into water, serious injury to occupants resulted.
Drift Considerations • If CAPS deployed from 1000’ AGL: • With 4 seconds to deploy, and 1500 FPM sink, aircraft will impact after ~45 seconds • Typical winds at 1000’ AGL are 20- 30 knots, or .3- .5 NM/ minute • So expect to touchdown approximately .2 to .4 NM downwind of deployment spot • If possible, take this into consideration when deploying, and/ or deploy slightly upwind of desired touchdown location.
