Bell 412EP Pitch / Roll and Heave Limitations

[EZY433]

Hi all, apologies if this is a guff question to you guys, however could you point me in the right direction to find out the P/R and Heave limitation for the aircraft when working offshore? Thanks in anticipation. SJ

It's whatever is written down in the Operators Operations Manual or Exposition or SOP or whatever the local document is that contains that information. For the B412 it's likely to be in the order of 2m heave and 10deg P/R.

and 10deg P/R.

That'll be an exciting ride!

....which is why I'd always take an S76 over a B412 for those jobs if given the choice

Ta for the info; you would like to think that this info is in the manuals you talk about GulliBell, however they are not for the operator I am currently working with. 10dgs P/R is warship flying Regards SJ

I don't even recall slope landing limits being mentioned in the B212 or B412 RFM. The landing limits info for ship ops should always be written in your local ops procedure, if you need to do that sort of thing....and as for the warship flying, I'd prefer to land on a warship any day over some of those smaller seismic survey boats in iffy sea state

p.s. I've seen 14degP/R in an S76 which I discovered is the point where it will slide backwards off the deck...if I saw that number in a B412 I think I'd be reaching for the HEEDS bottle

Bell 412 pich and roll limitation

I cannot remember the Bell 412 but the Bell 212 was 4 degrees pitch and roll and 5m heave (Bristow Ops manual Part A) and you needed a net on the deck or you would slide off.
Hope this answers your question.
