What Is Tandem, Static Line, and Accelerated Freefall (AFF)?

Introduction
When you first explore the world of skydiving, you’ll encounter three main training methods: Tandem, Static Line, and Accelerated Freefall (AFF). Each offers a different experience, level of involvement, and path toward becoming a licensed skydiver. This article explains the differences, advantages, and requirements of each method to help you choose the one that suits your goals.

1. Tandem Skydiving

Overview: Tandem skydiving is the most accessible way to experience skydiving without extensive training. You are securely attached via a harness to an experienced instructor who manages all aspects of the jump.

Altitude: Typically 10,000 to 15,000 feet

Freefall: Approximately 30 to 45 seconds

Training: Around 20 minutes of ground briefing

Parachute Deployment: Controlled entirely by the instructor

Ideal For: First-time jumpers, charity fundraisers, and thrill-seekers who want a single unforgettable experience

Benefits:

  • Minimal preparation required

  • Safest option for complete beginners

  • Great for bucket-list experiences or gifts

Limitations:

  • No solo control or progression toward a skydiving licence

  • Higher cost per jump

2. Static Line Training

Overview: Static line jumping is a solo skydiving method that uses a deployment system connected to the aircraft. When the student exits the aircraft, the static line automatically deploys the main parachute.

Altitude: Typically 3,500 feet

Freefall: None (until progression to freefall stages)

Training: 6+ hours of ground school before the first jump

Parachute Deployment: Automatic, triggered by the static line

Ideal For: Individuals who want to learn skydiving gradually, with strong emphasis on safety and progression

Benefits:

  • Solo jump from the very first descent

  • Structured progression through defined learning stages (Categories 1–8)

  • Cost-effective training pathway

Limitations:

  • Initial jumps are lower altitude and without freefall

  • Takes longer to reach advanced skill levels

3. Accelerated Freefall (AFF)

Overview: AFF is an intensive, high-altitude training program that puts students into freefall from the first jump. You are accompanied by two instructors who hold onto you during the freefall and provide in-air guidance.

Altitude: 12,000 to 15,000 feet

Freefall: 40 to 50 seconds (from jump 1)

Training: A full day (6+ hours) of classroom training prior to the first jump

Parachute Deployment: Student deploys their own parachute under instructor supervision

Ideal For: Those serious about becoming licensed skydivers as quickly as possible

Benefits:

  • Rapid progression toward A Licence

  • Full freefall experience from the start

  • Personalised coaching from instructors in-air and on the ground

Limitations:

  • More expensive upfront than other methods

  • Requires physical fitness and strong mental readiness

Method Altitude Freefall Training Required Who It’s For
Tandem 10,000–15,000 ft 30–45 sec 20 minutes First-timers, one-off thrill seekers
Static Line ~3,500 ft None (initially) 6+ hours Beginners wanting gradual learning
AFF 12,000–15,000 ft 40–50 sec Full day Future licensed skydivers
