• Landing net is tightened during installation to at least 2225N or so that any part of the net cannot be lifted by hand by more than 250mm above the deck.

Landing net are usually not supplied for fixed offshore platforms or rooftop structures. The following sizes are supplied depending on the CAP 437 classification of the helideck. Deck sizes are defined in CAP 437 Table1: D Value and Helicopter Type Criteria.

• Small landing net: 9m x 9m square of octagonal depending on the shape of the helideck.

• Large landing net: 15m x15m

Despite the CAP437 requirement for a landing net on some offshore helidecks, Helidex strongly advises against the use of landing nets on helidecks due to their inherent tripping hazard and the well documented accidents related to the tangling of helicopter wheels and skids to the net during take offs.
