Storing a HALO (High Altitude Low Opening) parachute requires careful consideration and planning. As an experienced skydiver, I’m often asked how to properly maintain, pack, and store these specialized parachutes to ensure they operate safely and effectively. In this comprehensive guide, I’ll walk through everything you need to know about storing your HALO parachute.
What is a HALO parachute?
A HALO parachute, short for High Altitude Low Opening, is a type of skydiving parachute that allows skydivers to jump from very high altitudes (up to 35,000 feet), free fall for an extended period of time, and open their parachutes at a low altitude.
HALO jumps are highly specialized maneuvers used primarily by military units for covert insertion into enemy territory. The high jump altitude and long free fall time make it difficult for ground forces to detect the incoming parachutists. HALO jumps also allow skydivers to cover long lateral distances to reach far away drop zones.
Unlike conventional skydiving rigs, HALO parachutes are designed to withstand the ultra-thin air and extreme cold temperatures at high altitudes above 30,000 feet. They are purpose-built systems with specialized features like directional glide capabilities that allow advanced maneuverability. The parachutes themselves are generally high-performance ram-air canopies.
Key factors in storing a HALO parachute
When storing a HALO parachute system, there are a few key factors to keep in mind:
– Temperature – Store parachutes in a climate controlled environment between 60-80°F. Avoid excessive heat, cold, or humidity fluctuations.
– Light – Keep parachutes away from direct sunlight or other UV light sources which can degrade the materials. Store in the dark when possible.
– Cleanliness – Always store parachutes clean, dry, and free of dirt, oils, or other contaminants. Don’t store on the floor.
– Packing technique – Properly packing the parachute according to manufacturer guidelines is critical for performance and longevity.
– Equipment orientation – Store parachutes with lines, risers, and deployment system accessible and not tangled.
– Container position – If storing in a deployment bag or other container, keep it positioned horizontally to avoid damage.
– Handling care – Avoid unnecessary handling and only touch parachute components when required to minimize wear.
– Insect control – Utilize sealed containers and insect repellent strips if needed to prevent insect damage.
– Tension – Avoid storing parachutes under tension, compressed, or stretched for prolonged periods.
Choosing the right storage environment
Choosing the optimal storage environment is the most important consideration when maintaining your HALO parachute system over the long term. Here are key guidelines for the storage space:
Stable temperature control
Aim to keep parachutes in a space with a stable temperature between 60-80°F. Fluctuations below or above this range, or rapid changes in temperature, can negatively impact parachute materials and cause them to degrade faster. Avoid direct contact with cold floors or walls.
Low humidity
Excessive humidity encourages mold growth which can stain and weaken parachute fabrics. Use dehumidifiers or desiccant packs to keep relative humidity below 65%.
Clean & dust free
Dirt, dust, and debris can bury into parachute fabric and abrade materials causing damage. Choose a clean, dust-free space such as a plastic bin or closet.
Dark storage space
Keep parachutes away from windows, skylights, and direct sunlight which emit UV rays that accelerate aging. Store in darkness whenever possible.
Good ventilation
Some air circulation will prevent excessive humidity build up while stored. Don’t tightly seal parachutes in airtight plastic with no airflow.
Free of chemicals & fumes
Avoid storing parachutes anywhere near fuels, oils, acids, or other reactive chemicals which can create contact contamination or off-gassing damage.
Elevated off the floor
Store parachute packs elevated off concrete floors, garage floors, etc. which can transfer moisture, oils, and dirt. Use shelving, pallets, etc. to keep packs off the ground.
Secure from pests
Rodents and insects can cause extensive damage if they start nesting in parachute packs. Use sealed bins and place insect repellent strips as needed.
Packing techniques
A properly packed parachute is vital for reliable deployments and to prevent unnecessary wear and tangling of lines, risers, and canopy fabric. Here are key packing guidelines:
Follow manufacturer instructions
Each HALO parachute system has specific packing procedures created by the manufacturer. Follow their instructions precisely each time you pack the parachute.
Take your time
Rushing through packing procedures is a common cause of problematic deployments. Work methodically and double check your progress.
Use packing paddles & guides
Specialized fabric paddles help position canopy sections neatly and avoid tangling or twisting of materials. Some rigs have built-in folding guides on the deployment bag.
Maintain symmetry
Pack each side evenly and mirror your progress to keep the entire canopy symmetrical and balanced inside the container.
Work out slack
Gently pull risers, lines, and fabrics taut to remove any slack before making each fold. Slack leads to entanglement on deployment.
Anchor slider correctly
The slider must be stowed upwards properly to allow orderly deployment. Follow instructions carefully for this key step.
Double check before closing
After packing the canopy, visually inspect from risers to skirt before stowing in the deployment bag and closing the flaps.
Log each repack cycle
Track the number of packing cycles and note any issues for your own records. Excessive repacking will necessitate professional maintenance.
Parachute orientation
Storing the parachute with proper orientation inside the deployment bag and in relation to other equipment is key.
Deployment bag orientation
Rest the packed deployment bag horizontally on its side. Never place vertical or upright for prolonged periods which can misshape packed materials.
Risers positioned outward
When sealed inside the deployment bag, the risers should face outward towards the side handle for easy access upon deployment.
Slider positioned upward
The slider must always be stowed upwards towards the canopy, away from the risers, to launch properly on deployment.
Lines free and untangled
Lines should drape loosely from the risers without any twists, knots, or tangles which could cause dangerous malfunctions.
Other gear neatly stacked
Pack away knee pads, oxygen system, altimeter, and other ancillary gear neatly so the full kit is organized for rapid access.
Flaps folded correctly
Fold protective flaps based on the manufacturer’s specifications to shield the deployment bag from abrasion or contamination.
Inspection & maintenance
Frequent inspections coupled with professional maintenance is essential to keeping HALO parachutes functioning safely and effectively over many years.
Monthly inspections
Every 30 days, fully unpack and inspect all components for any signs of wear, abrasion, damage, or deterioration issues.
Annual professional service
Have the entire HALO rig inspected annually by a certified parachute rigger to identify and correct any potential issues.
Full disassembly & cleaning
Take down the parachute completely about once every 100 pack cycles to clean every component before inspection and reassembly.
Line continuity checks
Use line gallery sleeves or other tools to verify line continuity from canopy to connectors before and after packing.
porosity tests
Fabric Porosity is tested using calibrated instruments to check for weak spots vulnerable to blow out at high speeds.
Control line strength tests
Test control lines and steering lines for minimum strength requirements using a tensiometer testing device.
Component replacement
Repack cycles, free fall time, and age will dictate replacement of worn components based on manufacturer guidelines to maintain proper airworthiness.
Storing in dry vs humid climates
Parachute storage procedures must be adapted based on the specific climate where they are stored. Here are key considerations:
Dry climate best practices
– Utilize sealed bins or wrapping to prevent moisture loss
– Use drying agents if humidity drops below 20%
– Gently flex fabric to avoid brittleness
– Check for static cling which attracts dust
Humid climate best practices
– Inspect for mold and mildew regularly
– Use wide swings in humidity
– Add additional exterior containment layers
– Deploy dehumidifiers or desiccants
– Pack loosely to allow airflow
Preventing degradation
To maximize parachute longevity and prevent material degradation:
– Maintain temperatures between 60-80°F
– Keep relative humidity around 50%
– Avoid direct sunlight exposure
– Use dark, sealable storage containers
– Repack at least once annually
– Perform regular inspections for wear and damage
Long term parachute storage
For long term parachute storage exceeding one year, extra precautions must be taken to ensure the system remains airworthy over many years.
Designate a secure climate controlled room
The space should maintain temperatures between 60-80°F with humidity around 50% year-round with no windows or direct light.
Thorough cleaning & inspection
Fully disassemble the parachute before storage and clean every component. Inspect for defects using porosity tools, etc.
Moisture barrier wraps
Wrap components in plastic sheeting or waterproof fabric bags as an extra moisture barrier. Avoid airtight packaging.
Cedar blocks in bags
Cedar’s natural insect and odor repelling properties help preserve fabrics when blocks are placed inside storage bags.
Desiccant packs
Several desiccant packs added inside storage containers will actively absorb moisture during the entire storage duration.
Log storage date & details
Document the storage date, inspection notes, expected removal date, and contact info for the responsible party.
Annual maintenance
Every 12 months, remove the parachute for a thorough inspection, cleaning, and repacking using authorized personnel before returning to storage.
Full inspection & test before reuse
After long term storage, perform a complete airworthiness inspection and a test jump before returning the parachute to active service.
