SHOLs

I am looking for a favour from anyone who is a bit (or a lot) more current than me on deck landings. I have been asked to do a trial/demo of a deck landing of a helicopter on a non-NATO warship. I don't think this ship will have an official SHOL, and certainly not for this helicopter. Can anyone please remind me if there is a standard generic SHOL to use in situations like this? And remind me of what "d" value I should have as a minimum? (Its been about 14 years, and I don't want to get wet!)

Thanks in anticipation!

If your client has the budget, you may want to do a short course first.

Two weeks with ETPS; https://www.etps.qinetiq.com/courses/Pages/hsit.aspx

Or five days with NLR; http://www.nlr.org/capabilities/helicopter-ship-qualification-training/

Nice idea, but I'm in-country and need to do the demo soon. I think the civvy equivalent requirements from CAP437 suggests landing area of 1 x D, plus obstacle free zone of another 0.33 D in front, so I am hoping the helideck will be at least 1.33 D long and 1 D wide (haven't got the dimensions yet!)

Caution: No previence experience

A Crab, interested by the question but only with a short detachment to the "Old" Ark (R08?) in the 70's, I comment only from the perspective of the technical issues surrounding the operations.

I dredged this up on the web and was fascinated by the degree of complexity in these operations...I cannot claim anything other than webcrawlers rights.

It gets interesting from around page 49.

IMAGEGEAR, many thanks - found what I was looking for on page 80 - a conservative generic SHOL for US Navy!
