Avoiding Canopy Collisions

by Lesley Gale
by Lesley Gale

Canopy collisions are most likely to happen in two situations: on deployment, or during the landing pattern. Recognising these scenarios and taking preventive action is the best recipe to stay out of trouble. Avoid! Avoid! Avoid!

1 – Colliding on Deployment

Possible Causes Include

  • Poor exit separation
  • Poor tracking – leads to poor separation within a group
  • Poor knowledge or loss of awareness of line of flight
  • Loss of canopy control due to nuisance factors or malfunctions

Avoid by Good Planning

  • Exit Separation – know the upper winds to assess the correct exit separation
  • Jumper information – be proactive! Know the number of jumpers on the aircraft, the group sizes, and what the groups are planning to do.
  • Clear airspace – create good separation with effective tracking
  • Correct packing – to avoid malfunctions

Avoiding Actions

  • Rear risers – steer away from danger during and immediately after deployment using your rear risers
  • Head to head – if a head-on collision is likely, turn right
  • Side by side – if another canopy is approaching from the side, turn away
  • Communicate – shout and open/close your legs to get the other jumper’s attention
  • Avoid body contact – it is better to have contact with material than lines. Body-to-body contact is the worst outcome.

2 – Colliding During the Landing Pattern

Possible causes include:

  • Poor or no flight plan
  • Erratic canopy control (fast flight, spirals, S-turns)
  • Confusing patterns – no defined approach sides
  • High speed approaches in the pattern – leads to rapid altitude loss, overtaking and blind spots during a large turn
  • Target fixation – leads to tunnel vision and a lack of awareness

Avoid by Good Planning

  • Effective flight planning – predictable pattern and landing direction
  • Hold landing direction – do not chase the windsock
  • Separate landing areas – does your approach suit the chosen landing area?
  • Alternate landing area – don't be afraid to land alone

Avoiding Actions

Top Jumper If there is a canopy below you, exit above using brake input. Distort the canopy below by stepping on the top-skin, causing it to lose altitude. Extend your legs! You must stop the canopy approaching.

Bottom Jumper Exit below with outside front riser or double front riser input. NEVER APPLY BRAKES

A great article with some suggestions that could be taught as standard practice for what to do if the worst happens. I would have to say that the discussion on 'S' turns needs more comment. They definitely have their place in canopy control, particularly for beginners & low experience jumpers, to avoid overshooting the landing area, especially if overshooting involves a hazard such as an active runway!! 'S' turns, like any manoeuvre, need enough observation, height & space to be performed safely. The problem is that they can create chaos & confusion or even a collision in the landing pattern. So by the time jumpers are experienced enough to be pulling at similar altitudes as the rest of the load or joining in with groups & especially going to boogies they should have the ability to plan & fly a pattern that doesn't need 'S' turns.

Thanks for making safety simple Brian!
