How To Go Skydiving: Technical Guide To Tandem And Solo Freefall Jumps

Learning how to go skydiving requires choosing a United States Parachute Association (USPA) certified dropzone, completing mandatory ground safety instruction, and selecting between a tandem jump or an Accelerated Freefall (AFF) solo progression course. Standard civilian skydiving jumps launch from 10,000 to 14,000 feet Above Ground Level (AGL), delivering 45 to 60 seconds of terminal velocity freefall at approximately 120 mph before parachute deployment at 4,000 feet AGL. Successful jumps depend on maintaining proper body arch geometry, understanding canopy flight dynamics, and strictly adhering to federal aviation regulations.

Dropzone Selection and Pre-Flight Preparation Checklist

Before stepping foot on an airfield, prospective jumpers must verify dropzone credentials and prepare physically. Operating under Federal Aviation Administration (FAA) Part 105 regulations, licensed dropzones adhere to strict maintenance schedules and equipment standards. Ensuring your chosen facility is a USPA Group Member site guarantees that instructors hold active ratings and that aircraft maintain FAA airworthiness certifications.

Essential Gear, Clothing, and Documentation

• Government-Issued Photo ID: Valid driver's license, military ID, or passport proving the jumper is at least 18 years of age (USPA requirement).
• Athletic Footwear: Low-profile, lace-up sneakers with smooth soles. Boots with lace hooks, high heels, or sandals are strictly prohibited due to line entanglement hazards.
• Fitted Athletic Apparel: Form-fitting layers such as compression tops, leggings, or flexible jeans. Loose, baggy clothing creates drag and flutter in freefall, interfering with harness security and instructor grip points.
• Personal Goggles and Jumpsuit: Provided by the dropzone; clear, plastic goggles fit over prescription glasses or contact lenses to preserve visual acuity at high airspeeds.

Mandatory Prerequisite Standards and Health Benchmarks

• Body Mass Index and Weight Thresholds: Standard weight limits range between 200 to 230 pounds (including clothing) due to maximum operational weight limits on tandem canopy systems (typically 500 lbs combined user weight).
• Nitrogen Decompression Clearance: Zero compressed-gas SCUBA diving within 24 hours of flight. Flying to altitude with residual nitrogen in the bloodstream drastically increases the risk of decompression sickness (the bends).
• Cardiovascular and Joint Health: Full range of motion in shoulders, knees, and neck. Uncontrolled hypertension, acute epilepsy, or recent shoulder dislocations require clear medical clearance from a board-certified physician.

Budget, Logistics, and Operational Timeframes

• Tandem Skydiving Cost: $200 to $300 for the jump package, with optional $80 to $150 additions for outside video/photo media.
• Accelerated Freefall (AFF) Ground School Cost: $300 to $500 for First Jump Course (FJC) instruction and equipment rental.
• On-Site Duration: Plan for a 3- to 6-hour operational window at the dropzone to accommodate weather holds, aircraft fueling, air traffic control clearance, and manifest scheduling.

The Step-by-Step Skydiving Operational Workflow

Step 1: Dropzone Manifest and Paperwork Clearance

Upon arrival at the airfield, report to the dropzone manifest office to complete standard liability waivers, age verification, and weigh-ins. Manifest staff assign your flight slot on a specific aircraft load and introduce you to your USPA-certified instructor or AFF coaches. Use this window to hydrate, clear sinus passages, and ensure all personal gear fits tightly.

Step 2: Ground School and Body Position Training

Tandem students complete a 20- to 30-minute harness and positioning brief, whereas solo AFF students undergo 4 to 8 hours of formal classroom instruction covering single-harness operation, canopy flying rules, emergency procedures, and hand signals.

Master the primary freefall posture: the belly-to-wind "banana arch." Keep your head tilted up toward the sky, shoulders rolled back, hips pushed forward into the air column, legs extended backward at a 45-degree angle, and arms bent at 90-degree angles with hands level with your ears. This symmetrical, belly-down geometry creates maximum drag surface area, establishing a stable center of gravity directly over the air column.

Pro-Tip: Practice your arch on the ground by lying flat on your stomach and lifting your thighs and chest off the floor simultaneously. Muscle memory built during ground school prevents involuntary de-arching (curling up) during exit acceleration.

Step 3: Harness Fitting and Equipment Inspection

Your instructor fits you into a heavy-duty nylon harness system rated for excess G-forces. The harness connects securely via four primary load-bearing detachment points (two shoulder hooks, two waist snaps) to the instructor’s main rig in a tandem setup, or supports a standalone dual-parachute system (main canopy and reserve canopy) for solo jumpers.

Inspect the rig’s primary technical components:

• Automatic Activation Device (AAD): A computerized barometer (e.g., CYPRES or Vigil) that automatically fires a pyrotechnic cutter to open the reserve parachute if the jumper is traveling at high velocity below a critical altitude threshold (typically 750 to 1,000 feet AGL).
• Reserve Static Lanyard (RSL): A mechanical cable connecting the main canopy risers to the reserve pin, instantly opening the reserve if the main canopy is cut away.
• Dual Altimeters: Visual wrist-mounted analog or digital altimeters, paired with audible helmet altimeters set to chirp at key pull and decision altitudes.

Step 4: Boarding, Ascent, and Exit Execution

Board the jump aircraft (commonly a DeHavilland Twin Otter, Cessna Caravan, or Super King Air) and sit in reverse sequence to your exit order. As the plane climbs through 10,000 feet AGL, perform a final gear check: check harness tension, confirm altimeter zeroing, and seat your goggles over your eyes.

At jump altitude (typically 13,500 to 14,000 feet AGL), the pilot opens the door and illuminates the green exit light. Approach the door frame with your instructor attached behind you. Do not grab the external frame of the door; keep your hands tightly holding your harness straps. On the instructor's count ("Ready, Set, Arch!"), push off from the aircraft threshold into the slipstream.

Warning: Never reach out to grab the aircraft door frame or door frame trim during exit. The force of the 90-knot relative wind can wrench your arm backward, causing shoulder dislocation or striking your body against the airframe.

Step 5: Freefall Navigation and Canopy Deployment

Within 10 to 12 seconds of exiting, your body accelerates to terminal velocity (120 mph for a standard belly-to-wind profile). Tandem instructors deploy a small stabilizer parachute known as a drogue chute shortly after exit. The drogue slows the combined mass of two jumpers to a standard 120 mph terminal velocity and maintains vertical stability.

At 5,000 feet AGL, prepare for canopy deployment. Signal your intent by waving your arms horizontally (the wave-off signal to clear air space above you). Reach down to the bottom right of the main container, grasp the plastic handle on the throw-out pilot chute, and pull it cleanly out of its pouch, throwing it laterally into the air stream. The pilot chute inflates, pulls the deployment bag from the container, stabs the lines, and lifts the primary rectangular ram-air canopy into the air stream.

Step 6: Canopy Flight, Traffic Pattern, and Landing

Once the canopy fully inflates overhead, perform a control check: check that the parachute is square, stable, and steerable. Unclip the steering toggles from the rear risers. Pulling the left toggle down tilts the canopy left; pulling the right toggle turns it right. Pulling both toggles down to shoulder height slows the forward speed and descent rate.

At 1,000 feet AGL, enter the standard airfield landing pattern consisting of three distinct legs:

1. Downwind Leg: Fly parallel to the landing area in the direction of surface wind movement down to 900 feet AGL.
2. Base Leg: Turn 90 degrees perpendicular to the landing zone, descending across the wind pattern from 600 feet down to 300 feet AGL.
3. Final Approach: Turn another 90 degrees directly into the wind. Keep toggles completely up at full flight speed to convert maximum momentum into aerodynamic lift.
4. The Flare: At 10 to 15 feet above the ground, smoothly pull both toggles fully down to your thighs in one continuous motion. This levels the canopy flight path parallel to the ground, dissipating forward kinetic energy for a soft foot touchdown or a controlled tandem slide-in on your seat.

[Aircraft Exit at 14,000 ft AGL] | v [Freefall Arch / Terminal Velocity (120 mph)] | v [Wave-off & Pilot Chute Pull at 4,500 - 5,000 ft AGL] | v [Canopy Inflation & Control Check at 4,000 ft AGL] | v [Pattern Entry: Downwind (1,000') -> Base (600') -> Final (300')] | v [Two-Stage Flare at 10-15 ft AGL -> Touchdown / Slide-in]

In-Flight Complications and In-Air Recovery Protocols

Unstable Body Position or Spinning in Freefall

• Root Cause: Asymmetrical body posture—such as dipping one shoulder, dropping a hip, or unevenly extending legs—distorts the air pressure hit, causing rapid side-to-side oscillations or high-speed flat spins.
• Actionable Fix: Force your head back to look at the aviation target or horizon, roll shoulders backward symmetrically, and drive your hips hard into the wind column to re-establish the primary high-drag "banana arch." If spinning persists, reset entirely: bring hands into your chest for one second, then snap back out into a wide, symmetrical star position.

Canopy Line Twists Upon Deployment

• Root Cause: Body rotation during pilot chute extraction or asymmetrical packing of the main deployment bag causes the canopy risers to spin as they extend out of the bag.
• Actionable Fix: Confirm canopy is fully open and holding air overhead. Reach up, grasp the left and right riser groups above the toggles, push them apart laterally, and initiate a vigorous kick-cycling motion with your legs (like riding a bicycle) to spin your body out of the twists. Clear all twists prior to the decision altitude (2,500 feet AGL).

Main Canopy Partial Malfunction (Off-Heading / Celled Tensions)

• Root Cause: Slider hanging up mid-way down the control lines, or stuck end-cells preventing complete cell inflation.
• Actionable Fix: Grasp both steering toggles and execute two deep, full-arm control strokes down to your hips, holding for two seconds before releasing back up. This pumps air into the outer cells and forces the slider down over the line stops. If unresolved above 2,500 feet AGL, initiate emergency cutaway procedures.

Emergency Cutaway and Reserve Deployment Sequence

• Root Cause: Unrecoverable canopy malfunction (e.g., total line entanglement, high-velocity spinner, torn fabric) below deployment altitude.
• Actionable Fix: Execute the primary USPA two-step emergency procedure prior to reaching 2,500 feet AGL:
  
  
  1. Look directly down at the red fabric Cutaway Handle located on your right chest strap, grasp it with both hands, pull it downward to your hip, and peel it clear from the Velcro. This mechanically disconnects both main canopy risers from the harness.
  2. Look down at the metal Reserve Handle located on your left chest strap, grasp it with both hands, pull it forcefully downward to your hip, and throw it clear. The reserve canopy will immediately open into clean air via spring-loaded pilot chute deployment.

Frequently Asked Questions

How high do you jump from when skydiving?

Standard civilian skydiving jumps take place between 10,000 and 14,000 feet Above Ground Level (AGL), offering optimal freefall times while mitigating high-altitude hypoxia risks. Specialized high-altitude jumps using supplemental bottled oxygen systems can ascend up to 18,000 to 30,000 feet AGL.

What happens if the main parachute fails to open?

If a main parachute fails to deploy cleanly or experiences an unrecoverable structural malfunction, the jumper disconnects the main canopy using a quick-release cutaway handle and pulls the reserve deployment handle. Modern jump systems are also equipped with an Automatic Activation Device (AAD) that automatically deploys the reserve parachute at a preset safe altitude if speed thresholds are breached.

Can you breathe normally while freefalling at 120 mph?

Yes, you can breathe normally during high-speed freefall. The high air pressure moving across your face actually offers an abundance of oxygen; however, first-time jumpers often experience a gasping reflex due to adrenaline. Focusing on exhaling deeply through your mouth during exit relaxes the diaphragm and returns your breathing cycle to normal.

How far in advance do I need to clear SCUBA diving before skydiving?

You must wait a minimum of 24 hours between your last SCUBA dive and any skydiving flight. Ascending rapidly to altitude with residual dissolved nitrogen in your body tissues drastically accelerates bubble formation, inducing severe decompression sickness (the bends).

What is the difference between tandem skydiving and solo AFF skydiving?

Tandem skydiving secures a student directly to a licensed master instructor using a shared dual-harness, requiring minimal ground instruction before jumping. Accelerated Freefall (AFF) involves an intensive multi-hour ground school course where the student wears their own dual-parachute system and jumps alongside two free-flying instructors who monitor control without being attached.
